Two AV programs running affects computer performance?

post #1 of 5
Thread Starter 
This is the "evidence" this guy from another forum posted for my question for his statement saying, "Running two anti-virus programs at the same time will cause conflicts."

However, I've never had this problem in my life. Not while running AVG Free and AntiVir at the same time, that is.

Also, this statement from the link, I think, is bologna:
Quote:
One side note: Anytime you install a new program or game on your computer, please deactivate your anti-virus program. Forgetting to do this can cause system instability, crashes or freezes.
I strongly doubt this because I've never seen it happen, nor have I seen anyone having this problem.

So my real, more direct question is... will running two anti-virus programs on the computer at the same time really degrade the computer's performance along with the effectiveness of the AV programs?

You might not notice if you're not using proc-intensive programs, but it will slow down your computer as you have two programs scanning every bit of data that you access. If you're running AVG that's all you need really...

Actually, it can cause problems. And its not just the fact that each program will be eating up memory.

Basically, if youre actively running twp separate antivirus programs, they arent just taking up additional memory but also searching the same files as the other, checking file integrity while the file may already be open in the other program, possibly cleaning/ modifying files, etc.

Most quality antivirus programs can do things at a driver and kernel level, the most basic level between your hardware and software. And you do not want something to go wrong or it can mean a format and reinstall is necessary.

As for disabling antivirus programs when installing a game or program, thats a valid concern. Games can also install things at a driver and kernel level, especially copy protection measures such as Starforce, and if you have your antivirus automatically protecting things, it can sometimes cause the game to stall, the install process to crash, the computer to restart, etc. Basically, the installer doesnt have the access it needs because the antivirus program can actually do too much.

I noticed the system slowing down in the Safe Mode, but would running both programs affect the effectiveness of the programs in terms of detecting virus?

Speed will certainly be affected because two programs are trying to index your hard drive and eating up memory. Effectiveness could also be argued because one program may detect that the other is editing/ scanning a file and report it as a false positive.
