Since upgrading to Windows 8 and the latest version of Avast I have to disable the Network shield otherwise my routers web setup page is extremely slow to load, or elements are missing, same thing happens when connecting to my cable modems web setup, both issues are fixed If I disable the Network shield.
I thought you guys spent extra time on the Network Shield to make it Windows 8 compatible?
-
Same issue here. Build 1473 is very buggy. It causes network issues and bsods. I swithced back to 1466 and the problem is gone.
-
This is still occurring as of the latest build, still no post from anyone on the dev/support team either.

Hi lash, what brand and model of the router do you have troubles with?
The same question goes to Broken Hope as well. Thanks guys.

Guys, are we talking about Avast7 Free, or Internet Security (with Firewall) ? Thanks.

It's Avast 7 Pro, doesn't appear to matter then brand of router since I have the same issue with my cable modem too, with Network Shield enabled accessing the web setup on either device is very slow, with Network Shield disabled it functions properly.

We have seen these problems in the past with WebShield. HW appliances such as routers sometimes have rather limited Web Servers and/or send the data is some specific somewhat non-standard way and this might confuse the HTTP parser (inside WebShield or Netshield). Would you be able to create a packet dump from the communication (e.g. in Wireshark) ?
Thanks. L.

Not even sure how to do that, The problem didn't occur in Windows 7, only in Windows 8 with Network Shield enabled.

No problems here accessing my DLINK router or Motorola Cable Modem.

Have you tried clicking around and accessing the various options? The first screen shows fine, but trying to access the various options takes a long time, the status bar of my browser gets stuck at transferring from 192.x.x.x

I'm having trouble accessing the page of my router, already switched to the Dlink but still not able to get it in the settings page, the page loads endlessly, and sometimes occurs BSOD ... = /

Same issue here, and now the network shield is blocking lot of sites. nshield.log is full of failures:
Here is a portion of the log: http://pastebin.com/9NwKQTra
(windows 8 x64)
-
My nshield.log file is full of entries also.
I just did a test, I enabled the Network Shield then attempted to access my cable modem, then I stopped the shield and here's the entries between starting and stopping the shield.

Hallo..
I'm not able to reproduce the bug here in Avast!, then I can ask you if you can specify the router/modem types where the problem occurs and firmware versions (for example if you are using openwrt etc..)
The slow-down problem occurs only with router pages (all or any specific pages), or on classic web pages too?
Does help if you restart the Avast Service by Service Manager?
Additionally, do you use another third party security software for traffic inspection? Firewall, parental control, etc?
!!! PLEASE, TRY TO REPLY ALL QUESTRIONS !!!
Thank you.
-
No problems here accessing my DLINK router or Motorola Cable Modem.
Well I have ADSL router D-Link DSL-2641B and I do have those issues. Windows 8 Pro x64 and Avast Free.
-
Doesn't just effect Win8 because I'm using XP SP3, AIS 7.1474, no third party security, using Netgear WNDR3300. Router page never loads, but everything else seems to working o.k. Unlike a couple of above people, the nshield.log is empty.
Question: What is the safest and correct action I can take with AIS to access my router login page on a temporary basis until this problem is fixed? Thanks.

I'm using an Asus RT-N56U router with stock firmware and a cable modem that is provided by my ISP, it's a custom design.
The slowdown only occurs when accessing 192.x.x.x addresses for me so far.
I'm not using any other software that affects network traffic, Windows Firewall is disabled etc.
Does the info from my nshield.log file not shed any light on the issue at all?
-
I'm using an ADSL router TPLINK TD-W8960NB and a TL-WA801ND access point. No slowdown, the pages are loading fast, but sometimes (about every 5.-8. attempt) the page never loads or elements are missing. This does not happens with build 1466.
-
Same issue here, Telewell TW-EAV510 ADSL2+/VDSL2 modem. Avast internet security and windows 8 pro 64-bit.
(I had to delete a lot of recent errors since it was about 1500KB in size)

Hallo
I have prepared new version of the aswnseng.dll with one fix which may solve the problem.
Please try it, and report results.
How to install the fix:
1. Download it from here http://public.avast.com/~polach/aswnseng_01.zip (http://public.avast.com/~polach/aswnseng_01.zip) and unpack it.
2. Disable the Self Defense in the Avast!. Go to the Settings->Troubleshooting and uncheck enable avast! self defense module
3. Stop the Avast! service. Go to the Control Panel->Administrative Tools->Services. Then locate the avast! Antivirus service ans stop it.
4. Replace the aswnseng.dlll in c:\Program Files\AVAST Software\Avast or where you have Avast! installed. You will need adminstrative rights to do that
5. Start the avast! service again in Services list
6. Enable Web Shield if is disabled.
Provide tests and report results.
Thank you.

Tried new aswnseg.dll as suggested and experienced same failure as before on XP AIS system.
I am re installing the "old" aswnseg.dll to avoid any additional problems.

Hi Klinker, aswnseng.dll is used on Windows 8 ONLY. Not even loaded on Windows XP.

Lukor:
Interesting..... I just rechecked the Avast folder and I'm looking right at it. There is aswnseng.dll File Version 7.0.1474.106 and I'm on an XP machine with AIS.
Whether it's supposed to be in there or not on an XP system, I still can't access the router login page.
-
The DLL is probably copied there as well, to simplify things, but it is really not used and on XP different code is executed. This means that either the nshield.log from other users are not relevant to the problem at all - and it is not connected with any of these network shield changes for Win8 - or, yours is completely different problem.
Could you please try if disabling any particular shield helps? Such as trying with Network Shield and then Web Shield turned off ?
Thanks.
-
Just tried disabling Network and Web Shields individually as well as simultaneously, but I still can't get the login page.
I only log in to the router around the beginning of each month just to check logs, change passwords and for any router updates, etc., so I know it was working prior to the latest Avast updates in October. Other than that, I really don't have any clue as to why I can't get the login page to load now.
-
And what about script shield?
-
This patch doesn't solved the issue for me.
-
I appreciate your help, but I'm going to have to put this issue on the back burner for now.
I'm not sure if it was messing with the Avast shields, an issue with my ISP (always a possibility) or if it was just a coincidence, but I spent the last 30 minutes trying to re-establish my internet connection after disabling the shields. Internet seems to be working now and I did a repair of Avast just in case which seemed to smooth things out.
Again thanks for the help, but I can't afford risking losing internet connection right now ....I'll post back when I can to address the router login issue, but will monitor this thread for possible solutions.
-
The new DLL makes no difference for me, still can't access local router/modem pages properly.
Here's a log of the test.

Hi,
don't know about the nshield.log analysis, we have to wait for Zdenek on this. However, it might be helpful to have a trace of the traffic that is causing the problems.
Could you try to record a packet dump from the session?
There are two options:
1. Wireshark - for those who like it and use it (like me). However, officially not yet supported on Windows8, if you have WireSharp already installed, please record the packet dump with it.
2. Microsoft Network Monitor
Let me describe the steps for NM:
1. download Network Monitor here: http://www.microsoft.com/en-us/download/details.aspx?id=4865
2. select appropriate version based on your os version (32bit or 64bit)
3. download to your PC, and run the installer
4. Confirm YES and NEXT during the installer prompts.
5. The installation has to parts, Network Monitor and Parsers - both should complete easily, ending with a NM shortcut on the desktop
6. After the installation is completed - you have to logout and login again before using the program.
7. Log in again, open Network monitor on the desktop
8. Click "New Capture"
9. New tab opens, click the "Start" button on the taskbar.
10. Do the traffic that causes problems -- such as accessing your router.
11. After the problem manifests itself, click stop to terminate recording.
12. choose save-as and save the capture into file.
13. upload the file or send me a link via e-mail
To uninstall, use control panel/ Program and Features. Uninstall both "Microsoft Network Monitor" and "Microsoft Network Monitor Parsers". Reboot is not needed.
One more question: does the problem vanish after turning Network Shield off? Or do you have to fiddle with other providers as well (such as WebShield).
Thanks.
Lukas.

The only shield that causes the behaviour is the Network Shield the WebShield is active and working fine.
I've PMed you a link to the captures, one with the Network Shield on and one with it off, on is the capture where it isn't working.

Lukor:
Follow up from yesterday.....for whatever reason (maybe Avast, maybe something else) something was keeping me from accessing the router web login from either the desktop shortcut or by manually typing in the address. I researched the issue further and determined that once the router login failed, the only way to regain access was to power off the router and reboot it, clear the cache, and then sign on manually using an alternative address. Once router web login was re-established in that manner, the desktop shortcut works again or the primary address can be entered manually. Apparently a failed login puts the router into a "locked out" status, regardless of whether it was Avast or something else blocking the router web login.
I thinks it's safe to say that my issue on my XP machine is unrelated to others on this thread just judging by the logs. Although I can't say for sure if Avast was actually the root of my problem or not, I will say that the router login page is very laggy compared to pre-October versions of AIS. It's not to the point of being unusable, but each page loads very slowly. Everything else seems to be functioning fine so I'm considering this issue resolved.
Thanks.

I'm seeing this same issue, and I've been practically pulling my hair out over it. I was sure my router was toast, but I just traced it down to the Network shield this morning as my work laptop didn't show the same issues when I brought it home. I have an Asus RT-n56u which I replaced with an Asus RT-n66u while troubleshooting, both of which run "AsusWRT" (Asus' newer firmware). I also tried my old Linksys WRT54g running DD-WRT. Access the router's GUI on either Asus is always excruciatingly slow and webpages sometimes don't load or don't load all the way. The Linksys was slightly better but was still slow/intermittent. Disabling Network Shield fixes the issue for me. nshield.log is full of failures. I'm running Windows8 x64, am connected via a Realtek-based USB wireless NIC, and have the latest Avast Pro updates. What can I do to help troubleshoot? I have network shield turned off for now but don't like the prospect of doing that indefinitely.
-
Any news?
-
Any news?
I second that question :) It's pretty obnoxious to have to do the 10-min shield disable anytime I want to hit my router config
-
So I take it Avast aren't planning on fixing this? If Avast can't be fully compatible with my OS then I will have to find another AV.
The fact Avast haven't even pushed out a program update to fix the Windows 8 issues says a lot about the company IMO.
-
Hi, we still don't have the fix for this router issues, Broken Hope, we are definitely planning to fix this - however we don't know what is causing these problems, and we haven't been able to reproduce them with any router or similar device here.
Regarding the other issues, BSODs in aswnet.sys, we have already pushed the update via the emergency update mechanism!
Lukas.

Glad I found this thread. Asus RT-N56U router. Windows 8 64-bit. Also thought my router was toast. Spent a least a couple hours flashing firmwares, factoring resetting. Then I noticed the Router Control Panel was a lot faster on other machines in my house. Machine that is having issues bringing up router control panel pages is on Avast 7.0.1474. However, machine right next to me also connected via Ethernet, is also on 7.0.1474 and has no issues but it is a Windows 7 machines. Looks to me as if its a Windows 8 issue. Not surprising since Win 8 is brand new. Avast should be a bit more on top of things like this I would hope.
I could swear it's making my Internet speed in general slower, but according to Speedtest.net, it's not. I'll just leave the Network Shield off until its resolved.
-
Hi Guys, could anyone of you with this problem try to capture the packet traffic, as I have described above? I've only seen packets from Broken Hope, and it would help to have more to find some repeated patterns that might lead us to a solution. So far we haven't been able to simulate this here.
Thanks.
Lukas.

We have checked five more router brands here, still no repro.
-
It's not just router setup that is difficult (ie. slow, incomplete screens, not saving properly, etc.) - as I mentioned in my previous post, even "LAN-Bridge Adapter" setup screens are messed up too! My multi-mode ASUS EA-N450 adapter configuration screens aren't behaving with a combination of Windows 8 PRO (64-Bit) and the latest patched build of Avast free. Need to disable the Network Shield before it all becomes good & fast! I don't like the idea of going online with one of the shields deactivated though. :(

Hopefully a stupid question, but you are testing with Windows 8 correct?
-
Microsoft made a couple of compatibility updates for Windows 8 today... Did anyone notice any improvement with Network issues?

The update includes fixes for Norton, AVG and Comodo AV but doesn't mention anything for Avast. But I'll be a guinea pig for this patch.
---EDIT---
So far, so good. Can any developer from Avast comment on the Windows update released today?
-
BUGS are cannot be fixed with compatibility updates.

Hi, so you have to devices with built-in web servers that we have problems with - would you please capture the packets for us? Thanks a lot!!!!
Lukas.
(any packter capturing tools is OK, even Ethereal/Wireshark can be installed if you check the compatibility options and set it to run as if under Win7)

Ha! You got us! We still test only on Windows 3.11 for Workgroups everywhere; maybe upgrading to at least NT3.5 isn't such a bad idea after all.

I made 2 captures with wireshark (with and without network shield). Without network shield the 1st page of router's websetup always working perfectly.
With network shield enabled the whole menu is missing from the left frame. Sometimes the right frame is empty, sometimes the picture is missing from header or some element is missing from the page. Sometimes the page is loads correctly. It's totally random.
I uploaded the captures to avast FTP. The file name is: lash78cap.zip
-
Great! Thanks a lot. Will go through the data on Sunday.
Lukas,

Lukas,
Still no update on this I guess? Still hard to believe you could break access to local router setup pages and not be able to reproduce it at all, it's obviously affecting more than just me.
-
Hi, what is really interesting is that it affects only your local router and not inet access in general. What is so different on the web pages sent by your router to the web pages sent by any other server available on the net. Too quick, or too simple, some bugs in the HTTP dialog, I don't know. That is the question that drives my mind - corrupting the traffic is very easy for network filter driver, selecting to corrupt only the router and not other web sites is quite tricky.

Well it affects both my cable modem and my router set up pages and it only started since you made Avast Windows 8 compatible and the issue doesn't present itself when the Network Shield is disabled or uninstalled, so it's definitely something you guys did.
-
Well here also,network shield prevent access to my router( D-link 524) web setup? ???
Disabled network shield no problem.
OS = Win 8
-
I am having the same issues. They wanted me to pay them 99.99 to remote connect and configure my computer to work right. Supposedly this will take Microsoft engineers and 100.00 to fix your problem. What kind of support is that. Sounds like it's time to but a different anti virus program. One that actually works with windows 8.
-
Hi lash, what brand and model of the router do you have troubles with?
The same question goes to Broken Hope as well. Thanks guys.
Hi, I will add one too. http://www.asus.com/Networks/Wireless_Routers/RTN53/ I can access it's Web Interface only if I have disabled avast network shield ???
-
Just joined avast forum to endorse the problem. I can't access my router web interface when network shield is turned on.
Router: Dlink DI-524.
OS: Windows 8 pro.
I'm glad I'm not alone. It took me hours to figure out it was avast network shield blame.
-
Still no fix, I'm sure they will still state they can't reproduce the issue either, even though it worked fine in Windows 7 in an older version of Avast. So whatever they did to make Avast Windows 8 compatible did this.

Problem with these routers not loading properly with Enabled Network Shield .
Routers:
* TP-Link TL-R402M
* D-Link DI-704P
* Edimax BR-6428nS
OS: Windows 8 x64
These are all local routers. Sometimes on rare occasions it doesn't load even in Windows XP.
-
Hi guys, we were able to reproduce it and we have a couple of changes that might fix it. Still testing internally.
Whatever Broken Hope means we did is that we have completely replaced the drivers behind Network Shield in windows8. It is definitely caused by these new drivers. No need to have doubts on this.

Any idea when the fixes will be pushed to the end user so I can enable the Network Shield again?
-
I have same problem - also metro apps are blocked - InTune, Windows Mail (I could not activate account for this forum by clicking the link from Windows mail)
SOMETHING IS ROTTEN - My license expires in 58 days ... then I am looking for other options more compatible with Win8 because it took me so far 1 day to troubleshoot why is stuff broken - blaming everything else but Avast ....
-
Hi, shame on us. We now know for sure, it was a mistake to buy any source code from Agnitum/Outpost, but we are really working hard on eliminating all the bugs and rewriting it. It will soon be better, thats all I can say now. Sorry!
-

Was it that bad? ???
-
Sometimes some websites seems to load longer than expected and/or some elements are missing. Most of the time on Facebook.
This also happens on rare occasions with Win XP.
---------------------------------------------------------------
Disabled the "Network Shield" temporarily and all is fine. And it does not drop the internet connection. This will be temporary until a solution has been found.
-
after upgrading to windows 8 and spending hours on what I thought was a network/browser browser problem trying to connect to my sky router and NAS admin web page I finally discovered that this is an avast problem
Any update on when this problem will be fixed?
if not soon what version of avast is it not broken on and where can I download it from?
Yes I know that all I have to do is to disable shields but whats the point of having shields if you have to disable them??
-
No problem with my sky router access win 8 64bit
Avast 8 beta 2
-
my thanks essexboy,
I installed avast8test5 and no more problems, the note on the the Beta web page says Windows 8 is not supported which surprised me for a new release...
The new interface takes some getting used to, I just hope that with all the additions and improvements that avast does not go the way of Norton etc hogging all the resources and slowing down the system.
Thanks again
-
Even with the new tools I have not noticed any slowdown at all, as they are only run as required ;D
-
Well that was short lived; upgrading to V8 fixed the web admin of my sky router and NAS box but gave me a more serious problem that whenever my laptop awoke from sleep mode the screen was either blank or the new look Windows 8 blue screen of death.
reverted back to a backup image I took before installing V8 and back to my original problem.... the lesser of 2 evils
no point in reporting this to avast as they do state that windows 8 is unsupported in the V8 Beta notes.

Now it detects my Router Web Setup as a malware.
BTW This is WinXP SP3.
(http://www.mediafire.com/conv/59781f0b4a0b568ad609aaab1df89b4e9a159827cc691e69a07f27a85e99365c4g.jpg) (http://www.mediafire.com/view/?e1kcn8agct022aq)
Disabled the Network Shield just to access the Router Web Setup, then that pops-up!
-
Please report it as a false positive - if it really is - this has no connection with Network shield, this is standard script detection inside VPS detected on some scripts on your router interface. Possibly false positive.
If you want, you might also send me the webpage source via email, I'll notify the guys here directly.
-
Here is the file that has been detected as Malware by the Anti-virus:
http://www.mediafire.com/?l0qj7cgrinpzsn5 (http://www.mediafire.com/?l0qj7cgrinpzsn5)
Saved using: File - Save As. From the browser.
-
downloaded the file, I can see this inside it:
<!-- BITDEFENDER VIRUS MESSAGE -->
BitDefender has found a virus in one or more of your files. Unfortunately, we do not allow infected files to be uploaded. If you feel that you've received this message in error,visit our support page.
I guess it wasn't false positive after all. I would recommend a full scan.
-
But that file is in the router web setup (by accessing the web setup).
And im just accessing the router's web interface.
How could it be infected with a virus?
-
Either your router is infected (strange) or something in the way browser / router. Such as some rouge browser plugin, proxy etc.
You can download different tool, say wget.exe and download the web page directly,
wget http://192.168.2.1/genmenu.asp (http://192.168.2.1/genmenu.asp)
(wget does not process the content, so infection risk is minimal)
Zip it with password, and upload so that your virus team can see what's inside.
-
Tried the wget program and it does not seem to work for me.
Needs an Authorization to download.

Please add me to your list of victims of this problem. I have the Asus RT-N66U (vs. 3.0.0.4.270) and I'm running Windows 8 64. Extremely slow to connect to web user interface entering via Firefox or Internet Explorer. When connected, I can barely use any features of the interface, clicking on functions results in nothing happening. Turn off Network shield and everything is fine with web interface.
Normal internet usage is not affected by this problem, everything except access to router web/ interface.
I tried adding http://192.168.1.1/* to exclusions, but it didn't work.
Running Avast Free 7.0.1474 with all latest updates.
-
Avast 8 fixes this issue.
-
So when will Avast 8 be available?
-
Now, just update !
-
I've tried updating, but it says that all program and definitions are up to date (Still on 7 though).
How do I update to 8, there don't appear to be any options from in the program itself?
-
So when will Avast 8 be available?
when beta testing is over.....and that may be soon as release candidate 2 are in testing now
-
Okay, then i have now updated to beta 3. :D
-
currently running 1489, windows7 x64 and when i try to reboot my ASUS RT-n56u rourter from inside the browser all 4 cores on my cpu max out, and my computer practically freezes. alt+cntr+del wont work and it takes me about ten minutes to get the mouse courser over the X on the browser to close it. after i close the browser all goes back to normal. it doesn't happen as soon as i press reboot, it goes through the process and when it hits 98-100% the computer locks up. this is the only time i have this problem.
this happens with chrome and Firefox.
i also have spybotS&D and spywareblaster installed.
-

Drop Spybot and try again.

Wow, overkill, no wonder your pc is overloading, spybot is bad for overloading the cpu, poorly written, always been the same since first release years back, internet explorer is usually the one that's affected by spybot.
-

The problem is that Spybot contains a feature called TeaTimer which blocks new additions and most changes.
It is what's probably causing your problem.

Hi all,
I just started using Avast Free after discovering AVG was ramdomly causing system freezes on 2 of my Win7x64 systems. Oddly 3 other Win7x64 never experienced the freezes.
Anyway since I started using Avast ver 2014.9.0.2011 everything has been working smoothly with no more freezes but I just discovered the same problem as has been discussed here, mainly that when I login to my Netgear FVS318g router I get a page of html or cgi code instead of the setup page.
The only way I have discovered to get the proper operation is to disable Web Shield completely. I tried adding exclusions for the router URL and I tried excluding scanning scripts on the router URL but neither of those worked.
Is it a setup problem that I'm overlooking or what?
Thanks for any assistance.
-
Everyone still on holiday? Still no solution...
-
Hi Barryd, we are currently testing a StreamFilter fix, that might have something todo with problems like yours. If you would like to help us test it, I might give you the fixed DLL tomorrow.
-
I would be happy to help.
-
Just created an account to report this same problem. I use an Asus RT-N13U router with DD-WRT firmware and web interface. I run Windows 7 64bit on one PC and Windows 7 32bit on another. Both have the latest version of free Avast. On the 32 bit PC, the router's web interface works ok. On the 64 bit PC, it always hangs after clicking a few things on the router's web interface. To solve the problem I have to click the back button on the web browser but it hangs again after a few more clicks. No hangs at all when I disable Avast shields.
-
We believe this should be fixed with the latest beta. Would you like to try that?
-
If I can easily revert back to non-beta version then yes, otherwise I'll wait.
-

Lukor... I use an Asus RT-N66U router, and every once in a while, I would get that same freeze, especially if I refreshed the Client Status screen (tells which clients are connected). It would refresh but never show any results. Using the back button, or clicking on another item in the menu would work, but it would still be refreshing if I went back. Using the AIS beta, this doesn't happen any longer, so I do believe that you have it fixed.

FWIW, I have had problems accessing the setup on a Comtrend DSL modem/router. When I go to 192.168.1.1 I get the login okay, but the router "home page" displays only partially and none of the menu items are visible. I hope the new version of Avast! will fix it.
-
The newer version (2014.9.0.2013) I updated to a few days ago does not solve this problem. I also notice a lot more random hangs when browsing various websites. Happens more with Firefox than Chrome but stops happening on both when I disable avast shields.
-
hi noleaf, that's very sad.
Would you mind sending me the outpout from "systeminfo" command. Such as:
- start/run
- type:
systeminfo >%userprofile%\desktop\systeminfo.txt
- send me the systeminfo.txt file from the desktop (you can write me directly to rypacek (at) avast.com
We re now investigating the possibility, that some windows hotfixes are causing these problems and would like to confirm if you have or have not them all.
Thanks a lot.
Lukas.

I think you have to be in command mode for this to work: i.e. start/run/cmd, then systeminfo >%userprofile%\desktop\systeminfo.txt.

whatever your prefer. both are the same.

Just registered to say I'm seeing the same problem shown here. Windows 8.1, Avast 2014.9.0.2011, Asus RT-AC68R router, Firefox 26.
Disabling shields allows me to access the router without issue. What's weird is that I cannot logout at all from the router - the router says I am logged out, but I am not actually logged out, because when I retype the router IP, I get put right in. Almost as if Avast is still blocking something on me. If I close out the browser, I'm logged out properly.
What's weirder still is the following sequence of events:
Disable shields
Enter router UI and login
Close out browser to force the logout
Turn shields back on
Open browser and try to go to any webpage - I'm instead asked to login to my router, even if I try to navigate elsewhere... very weird.
I rebooted the router to fix this, and it stopped happening... but this is really odd. I simply provide the info to help troubleshooting further... I can't imagine what's causing this to happen...
-
Hi apurohit8, would you mind trying it with the update (9.0.2013)? Thanks a lot, Lukas
-
Hello Lukor,
Just updated to 2014.9.0.2013 as requested.
Asus interface might be slightly better, but still hangs up on some pages... so it might be slightly better, but still not right. Disabling all shields makes every page work properly.
The issue where I was being redirected to the router every-time (the scenario I posted before) is fixed, though... so that's a step in the right direction... but the overall problem is not resolved.
EDIT: Actually, I'm noticing overall issues with Avast now that I didn't have before. Granted, I have the new router installed now, but I am seeing weird and intermittent stalling now more than ever. When I disable Avast everything works MUCH more smoothly. For example, I just started a Youtube video. It stalled out at about halfway through, and wouldn't go past there. I was monitoring the loading bar and it wasn't moving very smoothly or quickly. I then closed the browser, disabled shields, and then reloaded the same video... and it loaded up quickly and played without issues all the way through. This stalling seems to be happening everywhere... I don't know how long this has been happening or if it's crept up to this state, but I suspect Avast giving the above test...
-
I have now uninstalled Avast and replaced it with Avira... and I don't have any of the problems mentioned above. More importantly, Youtube videos don't stall or stutter the downloading (the video plays fine, of course - I mean "stuttering" of the download progress).
I really hope Avast fixes this, because I recommend software for many friends and family, and they all use Avast because of me. Some have purchased it as well. I would hate to give up Avast, as it has been so good for me in the past. Please fix this issue... and let us know if it's being worked on or if you need any more info, please!

Since there doesn't seem to be any activity here (disappointing) I wanted to answer your question at least. You can go to http://www.oldapps.com/avast_antivirus.php and see donwloads for older versions of software, including Avast...

I would happily try reinstalling Avast clean... but no one suggested that. The suggest above was to update to the newer version, which I did... and it didn't fix the problem.
Aside from uninstalling Avast and rebooting, is there a separate cleaner I should run to ensure I have a true-clean install?

Thank you for the clear direction. I will say that the "clear" program doesn't seem to do anything more than deleting folders? That being said, there were no Avast folders/files on the computer, other than an empty folder in Temp and ProgramData (win8.1). I deleted those as well, and reinstalled Avast. So far, looks like that fixed it. Thank you for suggesting the reinstall - I thought about doing this myself, but since the original suggestion was to upgrade, that's what I did.
Bottom line, looks like it's working properly again now. Thanks again.

It also cleans up entries in the registry which is what usually "messes" things up. :)

I thought it should, but it provided no indication of doing this. So be it.
