Question Question about AV and Conflicts
Hi all,
I know anti-viruses such as McAfee, Avira, and other ones will conflict with other anti-virus programs on the same computer, but what I'm not completley sure why AVs and anti-malware programs can be installed on the same computer and there are no conflicts. Right now I have McAfee and Malwarebytes installed, and they do not conflict, but if I had McAfee and Avira, they would, since that's 2 AVs. So why question, is how different is the scan of anti-malware programs compared to anti-viruses that an anti-virus and an anti-malware (or spyware) program can be installed on the same computer, but not 2 AVs and no anti-malware programs? I think it has something to do with the fact that an anti-malware program like MBAM scans for all infected files, not just viruses, but then, it includes viruses right? And the confusing part to me is that my McAfee also scans not only for viruses but other types of malware as well, like MBAM.
Thanks, Jason

Jason:

If you have multiple antispyware programs installed that have "real time" scanning, that's where the conflict comes in.

I personally use the free version of Malwarebytes and SUPERAntiSpyware, which don't have "real time" scanning, therefore I don't worry about a conflict.

Dear Jason08,
There is a very bad press about Spyware Terminator,mainly because it installs"Trawler tool bar". ST is one of those few free anti-spywares that has "real-time"protection. The Trawler can be totally disabled.

On my PC, even if i try to install another A-V, KIS 2009 will not allow it! I don't know how a-squared anti-malware and MBAM (real-time) co exist.

Now, this post in pcreview.com takes the cake! " Hi, I use three anti-virus programs together and they don't conflict with each other. I use Avast, Antivir and Avg, these are all free and don't slow down or freeze your system like some of the others do. I admit I nearly always delete or heal a detected virus because if you quarantine a virus one of the others will detect it somewhere later down the line. You must install Avast first then the other two in any order. When you install Avg you must click on advanced install and uncheck e-mail scanner. I set antivir to medium detection level in configuration, if you set it to high you get a lot of false positives. I set Avast on high sensitivty and leave Avg settings as they are. Antivir also has an anti-rootkit built in so this is handy. I hope this is some help to you."---

I usually think of it as when anti-spyware programs first came out it was different from an AV they detected different things AV caught viruses, AS caught spyware, AT (anti-trojan) caught trojans so they wouldn't conflict since they all detected different things,

But now they're all catching the same things now SAS and MBAM are both actually anti-malware programs as well as usually all AV's are now AM,

So I suppose there could be conflicts but because programs like MBAM and SAS are meant to be used as additional scanners they probably make sure to program them to work along with AV's and if any conflicts are found they try and fix them.

Dear Gizzy,
I now have SAS,MBAM sitting in the system-tray working in real-time along with KIS2009!Which program will over ride the other? won't there be a conflict there? Any suggestions? Will be gleefully accepted!

Malwarebytes Anti-Malware and SUPERAntiSpyware do not provide "real time" scanning unless you've converted from the free version to the pay version.

Update them and then do a quick scan with them about once a week.

So you have Kaspersky (paid), Malwarebytes (paid), and SAS (paid)?

@perfume - It's usually not good to run too many scanners in real-time,
It can slow down the computer and possibly cause conflicts which may not be noticed until all three detect the same piece of malware and fight over who gets to block it.

I'm not sure which program would override which, most likely KIS first.

more than one security program with real time protection are bound to conflict, if you use mbam free, you're completely safe. Conflicts lead to your computer getting vulnerable to viruses, malware, hack attacks since these programs with real time protection 'Kill' each other off

Dear Gizzy,
This was the exact answer i needed. Thank you. What i found was MBAM's response was faster! Anyway I have no choice,but to remove MBAM from the sys.tray. I did not notice any change in MY computer's speed as it has a 4Gb RAM, but your point is well taken. The lesser the RAM, the slower the comp. Thanks again!

Hello there blitz,
Nice seeing you back. Your assumptions are in sync' with Gizzy's. Thanks to you too!

If I had malware on my computer, and I ran a manual scan with McAfee, and simultaneously ran a manual scan with MBAM (free version), couldn't there be conflicts there? If so, then even without any real time protection it seems like if scans aren't timed properly there can be conflictions.
