My rig: Windows 7 Proffessional 64 bit, everything with latest updates.
I will start by saying that I do not know if this is an internet problem, avast! problem, a virus, or just a system problem. Hopefully I can get some tech support help here.
So randomly, my internet stops working. I am still connected, however I have absolutely no internet capability. Over the network signal on the tray, I have either the yellow triangle ! symbol overtop or no symbol at all (indicating a healthy connection). Either way, I can't connect to anything whatsoever. I can't even access my router through 192.168.0.1.
I also get an error through avast on startup:
avast! will not be able to protect mail/news (error 10044)
Please check that the avast! service (AvastSvc.exe) is not blocked by your personal firewall.
I also cannot activate the avast web shield. No matter what I do, I cannot activate it, no matter how many times I try. It tells me to activate the Avast! service, but I don't know how to do that, and either way I still see the AvastSvc.exe process active in task manager (which I assume is the Avast! service).
I am using Comodo Firewall and defense+ security. I have tried a variety of solutions, from disabling any combination of the two, to rebooting/resetting my router, to even system restoring, and nothing seems to work. I confirm that only my computer has this problem, as the other computer, my xbox, and the iPad (which I am using to type this) works just fine at the very moment. I have also done a full system scan and found no threats.
Is there any advice you can give?

Sounds to me like Avast is being blocked by Comodo. Keep in mind that Comodo is not only a firewall its a complete HIPS. Seems like Comodo and Avast dont play nice together. Lets try this. Completely uninstall Comodo and reboot. You will need to delete all the left overs from Comodo also. I believe they have a clean up tool in there forums. Reboot and see what happens. You are also on Windows 7 64 bit and you dont need a 3rd party firewall. Avast has a behavior blocker and Comodo has a HIPS. Both of them can conflict.

Try opening command prompt and running
ipconfig /release
ipconfig /renewand see if that fixes anything

If that's true, then how come Comodo is only blocking right now? Keep in mind I've disabled COMODO entirely at some points and that didn't solve this. (Did not uninstall, though)
and what does having a 64-bit system have to do with not needing a third-party firewall?

I get this error:
An error occurred while renewing interface Local Area Connection: unable to contact your DHCP server. Request timed out.
I'll uininstall comodo, and tell you my results.
Also, remember that the web shield doesn't work either, I don't even know what could be causing that.
-
I've tried both solutions mentioned, and nothing has changed.

Windows 7 Firewall has made leaps and bounds over XP and Vista firewall. With Windows 7 there is no need to use a a 3rd party firewall. Disabling Comodo does not do anything since the drivers are still there. Disable it and you will see its actually still running.
-
You FULLY uninstall Comodo? That was too quick. So now you have Windows 7 firewall enabled correct? Now try uninstall Avast. Here is a link of what Comodo leaves behind.

WAs it too quick? Is it supposed to be a long and painful process or something?
I am using windows 7 firewall, now.
Is what Comodo leaves behind so harmful? I don't remember ever installing a safe surftoolbar.
I'll post back after I've uninstalled avast and rebooted.
-
Rofl.
-
Well I guess I've uninstalled Avast!, as well, and I still can't connect to the internet in any way.
-
Revo Uninstaller in Advanced Mode is the best method. You need to remove ANY and all files and folders. Also remove any registry entries. Most good companies have an uninstaller.
-
his dns cannot connect.
-
Well this is where you start. So its not Avast and its not Comodo. Lets try flushing your dns. Go to CMD and run it under Admin. Then copy and paste this.
ipconfig /flushdns
Unplug your router. Unplug your modem. Shutdown your pc. Wait 5 minutes and reboot your modem. Then reboot your router then finally your pc.
BTW derry...................Unless you have some advice to add stay out.

Sorry i was just implying that his DNS could not connect sorry if i intervened.

Are you connected via wireless or ethernet? Are you sure that all your modem and router lights are on? Are you sure its not your ISP?
-
Hope your problem is solved sorry i could not be of more help. ;D
best wishes
-
Are you connected via wireless or ethernet? Are you sure that all your modem and router lights are on? Are you sure its not your ISP?
Well realize, for what it's worth, that my modem and router are the same device, in a gateway. Probably means nothing, but may as well clear that detail.
I'm connected via ethernet, with all other devices except my xbox connected wirelessly. All of them can connect successfuly, pretty much ruling out that it's the ISP. All the necessary lights on the gateway are on.
After trying what you said, I am still unable to connect.
-
Ok lets check this. Open up the Control Panel and click on internet options. Once there click on connections/LAN settings. Be sure that "automatically detect settings" is checked off and not proxy.
So you cannot connect to the internet using with IE or FF?

Yes, "automatically detect" is checked and proxy server is unchecked.

Did you see my last edit?
-
Did you see my last edit?
Just saw it. No, I cannot connect with anything. Not with FF, MSN, my email, or any update programs. I don't have internet explorer (deleted it a long time ago), so I can't check that in particular.
-
Of course you have IE. You cannot delete it. Its part of Windows unless you did a slim install. Lets check your host file.

Nope...this hasn't worked.

Maybe its possible your NIC is no good. Is this a laptop or desktop? Is your ethernet cable in good shape? So was your host file normal?

It's a desktop. It could be your idea of a hardware fault, but this motherboard is only about a year and a half old, and yes my ethernet cable is fine. IT's only 4 feet long, anyway.
The host file had a few entries in it, but nothing out the ordinary, just stuff for adobe updaters and the like. I've had corrupted host files before, so I know what to look for.
However, it might be worth noting that in the microsoft page you sent me, I had to use the regular root to access my hosts file, not the one suggested for 64-bit systems, as that one did not work.

Doesn't matter if the mobo is only a year old. I have seen them bad only after a month. The one thing you can try is buying a usb wireless adapter and then seeing if you can connect. If so then your NIC is no good. Did you try running a ping/trace route?
How to run a ping, if your computer is Windows Vista or Windows7:
Click on the "Start Orb" and then type "Command Prompt" in the "Start Search" field.
From the search results, click on the "Command Prompt" icon that's listed under "Programs."
After the "Command Prompt" window is open, type: ping -n 500 [hostname] > ping.txt
(without the brackets)
Example: Example: ping -n 500 YourHostedDomainName.com > ping.txt
Depending on the network speed, this command will run for several minutes. Once the diagnostic is complete, the results will be saved in a filed named ping.txt.
How to run a traceroute, if your computer is Windows Vista or Windows 7:
Click on the "Start Orb" and then type "Command Prompt" in the "Start Search" field.
From the search results, click on the "Command Prompt" icon that's listed under "Programs."
After the "Command Prompt" window is open, type: tracert [hostname]
(without the brackets)
Example: tracert YourHostedDomainName.com

I agree. I've had gigabye boards die in months, they're no good.
I have, actaully. I've done tracert to a few websites, and it worked fully.
Well I am upgrading my rig within the month, so I won't spend money on a usb wireless (I hate those personally, anyway).
-
Wireless usb was just an idea. You can try running a scan with Dr.WebCurit. It does not need updating. A new version comes out about twice a week.
So you can ping out yahoo?

Also run a rootkit scan.

Indeed I can ping yahoo. It works fine.
Well, I'll do those, is that for the error 10044 and my web shield being deactivated? Because there was also that problem as well.
-
I am just trying to eliminate everything. If you can ping Yahoo then your NIC works. I take it your typing off a working pc. Just download those two items and put them on a usb stick. Then plug them into your broken pc and run them.

As I said, I'm typing off an iPad. I just put in a wireless USB and I will get the files through it. I'll post back after I have run them both.
EDIT: Well, looks like I can't even access anything through the wireless, either. So I don't know what to do, as I can't access anything through network, and I don't have a USB drive.
-
You will need to get a usb thumb drive or else burn them on a cd with another pc. Maybe a families pc. Does Windows see the wireless usb and is it
configured in your gateway properly?
Out of curiosity does Windows Update run?

I managed to transfer through the network. Apparently my computer is still on the LAN even though it can't access the internet.
I configued the Wireless USB properly. I've worked with it before on other computers and I know it's working. My gateway is awesome in that the uPnP can basically auto-config for everything, so I never have to worry about any errors.
As in, when I boot up? No. But I do have Windows Update enabled, if that's what you were asking.
-
Most newer pc's have a recovery partition to boot into. Sorry but this is not what you want to hear but its always a good idea to keep a system image stored on an external drive for when problems arise like this. Windows 7 even tells you this and has its own backup imaging program. Why in the world would you disable Windows Update? Can you open up Windows Update and run it?

I think you misread my comment. I do have it enabled and active.
Yeah, I would truly do backups, but the problem is I'm money tight and don't have the funds to support a drive large enough to do it (right now I'm still using old drives from like 5 years ago, one is 80 GB and another is 200 GB for personal affects/movies/video games.)
-
Money is no reason when you consider loosing precious memories and photos. Heck you can get a 1TB external drive for $100.
-
Well I ran the anti-rootkit and antivirus programs you sent me. The doctor found nothing, but the tdsskiller found a threat in c:\windows\system32\drivers\sptd.sys. Is this genuine, or too risky to delete? Or should I delete it anyway?
-
That usually is a drive related to Alcohol l20 or Daemon Tools.

Hmm. It's clean then, in that case. I guess that doesn't fix anything for me either.
-
How far back do you have fro using system restore?
-
Actually, for some reason, I only have this morning; about 10 minutes before this happened. I've restored to that point and nothing has changed.
-
Run a HiJackThis log and post it here.
http://free.antivirus.com/hijackthis/
-
Okay. I attached the log to this post.
-
This is not good.
R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyOverride = *.local
-
What should I do? Delete it? What does it mean?
-
Click on then select "fix". Reboot.
-
I've done it. No dice.
-
When you run another HiJackThis log does it still show up?
-
just throwing out a shot in the dark here:
did you happen to install comodo secure dns? maybe your router dns and the one on your machine do not match? its worth lookin at anyway, since the other steps havent seemed to help so far. ???
-
That's actually a very good idea: In fact I have installed Comodo Secure DNS. I considered that, but the problem is I don't know how to get rid of it, and I'm not sure if I still have it since I've switched ISPs after I've installed it.
-
Switching ISP's does not switch your DNS. Your dns settings are in your pc.
-
Alright. Good to clarify that. How do I reset my DNS, then?
-
in the network and sharing center on the left pane it should say "change adapter settings" right click on an adapter and choose "properties" highlight the ipv4 then press "properties" again.. tick the radio button to "automaticallly detect dns settings" or whatever it says.. you may need to do it for ipv6 also
-
Ahg unfortunately, both of the DNS settings were already set to automatic. I had a feeling that I got rid of Comodo's secure DNS a while back, and I guess I was right.
-
When you run another HiJackThis log does it still show up?
Sorry. I missed this post. No, in fact, it does not.
-
Mmmmmmmmmmmmmmm. Sorry running out of options besides doing a reformat. Have you tried doing a system file checker? Open up CMD and type:
SFC /SCANNOW
-
Okay, I need admin priviledges though. How do you run a command in cmd with admin priviledges (yes my account is an administrator).
EDIT: Never mind, I had a herpaderp moment. I'll post back wehn it completes.
-
Right click on command and select "run as admin".
-
Well, finished the scan, no errors detected.
-
Well honestly ..............Since I am the only one nice enough to help you out I am at a loss. The only other thing to do is reformat your drive.
-
Well, alright then. I'll just reformat when I upgrade my rig this friday, then. I was hoping not to have to re-install Windows 7, but oh well.
-
Flyboy, just want to double-check that you have thoroughly removed all previous security software?
If you have then please try this. It has helped in the past. Not everyone but it has helped some.

Fix Winsock Manually on Windows 7
1. Open up the command line utility and enter:
netsh winsock reset catalog (resets winsock entries)
netsh int ip reset reset.log hit (resets TCP/IP stack)
2. Reboot your PC

Good idea. Haven't thought of that since XP.

Just did it using the .BAT on the website provided ran as administrator. Nothing.
-
Did you download the file and run it? Looks like its time to wipe the slate clean and start all over. BUT..............This time do it right. Get an external HDD and make weekly backups using a system image. Windows 7 backup is good but Paragon Home and Recovery Free is better.
-
I'll see about the backups. But either way, thanks for the help.
