Thanks, I'll be sure to give them a whirl.

I've been pretty happy with AVG. I had used Avast! previously, but read some article that ranked virus scanners on their resource usage and decided to switch. 

To everyone saying that AVG "isn't the best": please recommend some alternative FREE, off-line virus scanning software that you think is better.

M Smythe already answered this question, although Trend Micro is slipping somewhat.

I use primarily Kaspersky and Nod32. Small and fast, and also far more thorough than most of the other options.

I saw guy who paid ~100euro more for his 3G data traffic just because of this AVG "fake" traffic behavior which was indeed very real problem in his wallet.

Turned it off after a day. Slowed my "Internet Experience" right down, with web pages pausing before loading. 
Pointless, AVG, pointless.

I have found that V8.0 is a backward step compared to the previous versions. I don't believe it is what customers want.

@ Alexander Holland. Haven't had your experience, but we all know that software often does odd things on different computers, even between ones that are running same hardware and same disk images.

While AVG is less resource hungry than Norton or Mcafee, ive also noticed it detects far fewer infected files and can almost never disifect them, it can only delete or quarantine them. There are far many far better and even less resource hungry AVs available, Kaspersky and Trend Micro to name a few

Would you care to advise us of what "GOOD" memory resident antivirus programs you're comparing?

nobody here knows NOD from ESET? nobody checks VirusBulletin? OMG

Back when Virus Bulletin was ad-paid-for ( now it's a Give Us All Your Information, Maybe Pay Too, THEN we'll perhaps permit you to see our results... )

There was one anti-virus software that always topped 'em all with the 100% awards
( VB's 100% awards were simple: any AV software that caught 100% of all in-the-wild viruses, got it: any that didn't, didn't )

Eset.

was where they were at.

I don't know if they're still the best, nor do I know if it's still the same company

( lived in Linux for so long, without Wine, too, that I only get reminded of what price Windoze users pay when I'm working on their systems -- which I don't bother to anymore, since there isn't any hope of winning )

It was also, btw, either the quickest or very nearly the quickest.

AVG is crap anyway, does anybody still use it?

I used the 7.5 for a while, then they released the v8 update, I started the install but read the new EULA.. let me just say that I use viruskiller AGAINST such thing as they give themselves permission to do, not to have it actually become the malware.

If we're saying AVG is the best by comparing it to NAV and McCrappy, then sure, it's fantastic. When you compare it to GOOD antivirus programs, it's not bad, but far from the best, and far from the least resource intensive.

They are unfortunately leaving their great roots and turning into terrible bloatware. The new Resident Scanner (avgrsx.exe) every now and again takes up 99% CPU time for about 30 seconds. Unacceptable.

Sigh, too bad.

For what its worth, AVG still is the least resource intensive and buggy software in the security space that I know of. They are the most responsive to problems, unlike our friends at symantec and mcafee that consume all CPU and memory, as well as destroy entire systems.
