Can Avast! Pro co-exist with MS Security Essentials?

Also, is there a simple way to temporarily turn OFF Avast (as there is with MSSE)?

It does not need to be uninstalled.  All that needs to be done is to turn off "Realtime Protection".  Please give correct advice!

You can turn off Avast by right clicking on it's system tray icon and mousing over "avast! shields control" and then choosing a period to disable them all for.

NO! disabling realtime protection only is INSUFFICIENTas it could still possibly leave low level drivers of MSE running.

these drivers could STILL conflict with Avast! drivers, causing potential problems like freezes or BSOD.

please uninstall MSE

No sir, you did not.  You gave the member the impression the only option was to uninstall the product and that is not correct.  The product can remain installed as long as the "Realtime Protection" is turned off.

Use the Windows Services GUI to disable MSE or far better just uninstall it. :)

You might get away with it being disabled in that mannor for a while but there is still the chance of avast detecting it, much safer with it removed completely.

Every reference on that site indicates "real-time".  Here's what is indicated regarding on-demand.

Quote
However, you can have an on-demand scanner, such as Malwarebytes, installed.  Malwarebytes offers two different scanners – one on-demand (free), and one real-time (paid).  The on-demand scanner does not conflict with MSE’s real-time scanning.

Now, when one disables real-time MSE the only tool remaining is an on-demand tool.

I do admit, though, the OP didn't specifically indicate what OS is being used and that page states XP is handled differently than Vista and Windows 7.

As already mentioned by AntiVirusASeT that even with being disabled there are still low level active drivers that may conflict so as advised dont install two AV's, dont know why your arguing this as your not going to win ::)

If you had read the thread correctly

 Not only should you remove your current anti-malware product(s), you should also uninstall any free or trial anti-malware products that may have been installed on your PC when purchased, even if never activated.

Winning!?  What are you on about!?

It is clearly written that it is two real-time scanning tools that is the problem.  And it is also clearly written that one on-demand and one real-time scanning tool is not a problem.

Now that page was provided as being the page to go to for the information needed and that is what is written.

You think it's an accident that there is a very clear distinction between the "real-time" and 'on-demand" tool in every reference to a scanning tool?

The on demand tools they are suggesting can be used are programs such as Malwarebytes and Malwarebytes isnt an AV

You are always free to try having 2 installed AVs.  Active or not.

You are free to try other things also, like; try out for the Olympics....swim the breadth of the English Chanel....climb Mount Everest....or if you just want to stick to computing, running a sandbox inside a virtual machine that is running in a sandbox.   

All these things you are free to try.   Some will even rise to the challenge and succeed.   But for most people, "free to try" ends up meaning "free to fail".   

The real challenge seems to be finding a resident AV that will shut off all real-time features, and stay off through all times it is installed.  They are not made with this in mind.

Another Quote from the same link since you cant seem to find the correct reading material

Can I have more than one real-time anti-malware product installed?
 
No.  Having more than one real-time anti-malware product installed will compete with other anti-malware product(s), and can cause severe performance problems and system instability issues, and may limit the effectiveness of the products installed.  Even if you attempt to have more than one product installed, with one active and another disabled, the disabled product will likely still have active components and/or drivers installed that will conflict with MSE.  The important issue here is that any other product with real-time scanning will conflict with MSE (or any other real-time product).

I didn't mean to start a war!  Currently, I will limp along with MSSE disabled and see what happens: No problems for the last week or so. I like to still have MSSE for the occasional targeted scan, just as confirmation. MSSE worked great for me for a long while, until a Sun Java update (which I don't even recall having downloaded and installed) became infected (according to Avast! Pro).

Thanks, Dch48, for the tip on disabling Avast! Pro temporarily.

I consider the topic closed. I DO really appreciate everyone's input. Thanks!

There are numerous very good second opinion options for performing targeted scans of files and folders and none of them involve running the respective programs in real-time including Malwarebytes, SuperAntiSpryware and Slim Cleaner.   All three will do a targeted file and folder scan by right clicking on the file or folder you want to scan.

You can also use the VirusTotal for a single file scan

https://www.virustotal.com/ (https://www.virustotal.com/)

In addition if you like MSE you might to consider using "MSFT Safety Scanner"

http://www.microsoft.com/security/scanner/en-us/default.aspx (http://www.microsoft.com/security/scanner/en-us/default.aspx)

The drawback with MSS is that you have to re-download it every 10 days or so to have the MSS file with the latest malware definitions.

Personally, I uninstalled avast! a long time ago and use MSE and have removed avast! from many, many computers since and will continue to do so. avast! Way too intrusive on operating systems. Windows was built under the Microsoft model. Not avast!'s.

a check on his posts shows that hes a rude user who previously made assumptions based on the fact that he thinks avast is behaving maliciously on his system (even though the obvious fact is that it is at most a faulty install on his system). refusal to work with avast developers to help diagnose the problem.

most probably results in him being frustrated with avast (even though it is his own fault) and trying to take revenge since the last post in 2011 by trolling...

Actually the web site has been valuable in diagnosing and comparing symtoms on the equipment of folks who choose the software and want to keep it. That's not trolling. And I've also noted in previous communications that avast! is actually a good product. Of course that was long before all of the unneeded bloat was configured into the standard. Google Chrome, webrep, and some others. And opinions vary so scribble what you wish.

As far as any opinions on what I assume, please understand that just because someone sits on a forum endlessly reciting the old uninstall and reinstall gag everytime someone's computer gets fudged up with this thing doesn't make you a developer . If I believe ( based on genuine experience) that a "developer"  ::) doesn't have any idea what they are talking about then I'll usually make that view known so that they understand that they aren't addressing the average user who would blindly follow the herd.

So, not rude. A realist.

And my computer never gets messed up, btw. Never. At least it hasn't in many years. Regardless of software, it's how the user manages their hardware and surfing habits that premise how well it functions. So if I'm discussing an issue it's usually regarding some other poor souls problems after just hitting the gimme, gimme, gimme buttons and tick boxes.

I will leave you with the fact that I have seen very, very few general pc problems from users of MSE than that of avast! users. Think what you wish. I really don't care.

A simple peek at the threads should reinforce the notion.

It's software, folks. Nobody is out for "revenge". If a software assumes the role of the users logic and it impedes progress in return for some model of growth then you uninstall it. Simple. You find what works for you. And when you do then you'll be of the more informed position to comprehend what "testing" truly means in a room full of self proclaimed "developers" who are only moved by the market share.

My experience with avast! and Windows Defender

I initially purchased a license for avast! AIS in the summer of 2010.  I had been using the free version of avast! for few  months before that.   When I purchased my first Windows 7 computer I left Windows Defender, which was only a anti-spyware program at the time, enabled on each of my network computers.   Eventually I added SAS Pro.   Everything worked fine.

During this period I set up my own personal avast! configuration, created numerous scans which I ran frequently. 

Between September and November I converted my entire home network to W8-DP.  avast! at that time was not compatible with W8-DP so I used W8-DP Windows Defender.  Windows Defender for W8 is a full fledged anti-malware program.   It also has very few setup options.   Maybe five at the most.    So it was basically a set once and forget about.   Indeed a lot less problem than the way I had previously used avast! AIS with all my personal tweaks.

Anyway when W8-CP came out I upgraded my network computers to W8-CP.   At this time I noticed a significant slow down in web-page loading using Firefox and a noticeable slowdown in file transfers across my network.   So much so that I decided to give avast! AIS 7 a try.  So I disabled WD since it can't be removed and installed AIS.

Why this long story?  I am coming to the reason. :)   Having noticed that WD for W8 provided very good protection without any user intervention or tweaks I decided to try the same thing with avast! AIS 7.   I decided to install it set a few options in the Setting menu and forget it.  No special scans.  No non special scans.  Nothing but just watch the orange ball occasionally rotate and an an occasional boot scan.

What I found is that avast! AIS 7 used as is out of the box (except for the few changes in Settings that I made) is not a bloated program with respect to memory usage.  It is a lot lighter on my systems than Windows Defender was and I have learned to trust running it basically as it came out of the box as it were.   Once a week I run some on-demand scans with Malwarebytes, Norman, McAfee stinger etc just in case.  So far they have found nothing.

P.S.  I do not use "Safe Zone".

As I've said before, I had some severe problems with MSE that made me dump it in favor of avast! The problems were all on the Vista Home Basic machine and were things that the main user would not have been able to deal with. There have been zero  problems on any of the computers here using either the free version or the full AIS package. I am a big fan of Microsoft and will always use their offerings to do specific things before trying alternatives. I use IE, WMP, Windows Mail, Outlook Express, Word, Excel, etc. but MSE is the only Microsoft product I was completely disappointed with.  I don't use any of the Windows Live apps but that's just preference since they all work and do what they're supposed to.

Documentation is all over the internet if you do a search and is widely common knowledge, you do not install two antiviruses on the same system, disabled or not.

+1.

Only one  AV on any computer at any time.  You can check with other on-line scanners, or use the Free or Paid version of Malware Bytes Anti-Maleare, which is NOT an AV with Avast OR MSE.  (But not both!)  One AV, either Avast or MSE has to be removed to avoid conflict.  Obviously, since this is an Avast forum, we are favorable to Avast for it's several times a day updates, cloud protection, Boot-Time Scan, Optional Web-Rep and Phishing Filter, which MSE does not have.

The only thing good about MSE is there is no license key required.  You install it, and forget it.  But the updates aren't as frequent as Avast along with the other things above.

However, you must only have one AV on your machine.

I want to thank all the in-the-know people on this thread; the information helped me
to realize about the conflict between the two.  For me, the issues started when Avast!
updated its version, so I turned off real-time protection.  Eventually even that wasn't
good enough, so I chose Avast over MSE.  The main thing is pick one or the other,
though on this website we would lean quite a bit toward Avast.  And, thanx again to all!
