Do not make the mistake some people make by thinking that commercial AV programs are somehow magically better because money is involved. The money only really means they have a motive to give you false-positives.

They want you to feel afraid about the multitude of possible virii and malware they detect. ClamWin has no motive to deceive you with false-positives or to try to scare you into buying more garbage.

I set ClamWin to not run at startup and not scan things in the background. Sometimes that may help avoid a problem, but I scan things manually by using the integrated (And optional) right-click menu.

Another great thing you may want to look into is Spybot: Search and Destroy. Again it is freeware and works wonders. Google will again tell you where to find it.

It will prevent and/or remove most malware just as easily and effectively as the for-profit programs that will try to scare you into purchasing.

Both are essential to a secure computer in my humble opinion.

Again, thanks to DarkKnightH20 for this thread. (These may also be worthy additions to your “Securing Your Computer” page, if not already there. I have yet to reach that one at this point)
