Do you mean you have two AV installed that is not recommended. Even if not running the real time scanners together having two AV installed can cause problems. If you want to do an AV scan with more than on AV try using the online scanners or use the Portable Apps version of Clam Win which will not interfere with any installed AV.
Hi Anthony,
I have WinXP Pro, Home, and Media Center PCs that I maintain for friends.
They are all set-up with IE7 and IE7Pro with Ad Blocker enabled.
The AV programs or security products I have installed are Avast! as "real-time" scanner. Also installed, up-to-date, and used as desired are Malwarebytes, AVG 7.5 Free Edition, SUPERAntiSpyware Free edition and SpywareBlaster. These identified and removed several pieces of malware over the last year. Personally I run Malwarebytes "quick scan" daily.
I have experienced no conflicts between any of these products. I normally update and run these even with Avast! Free still running. Of course, I don't have more than one scanner running "real-time". Every now and then I even use ESET or Panda on-line scanners just to keep up-to date on their use. This is also with Avast! still running "real-time".
Best wishes,
