Of those, I've personally used Trend Micro (terrible), Norton 360 (caught stuff, but overloaded my PC), ZoneAlarm (would recommend) and AVG (highly recommend).

I've used many of the top ones on various computers - each has their own special features that I like. McAfee is OK, Norton is good but a memory hog, TrendMicro I disable on ANY computer I sit down on, AVG I've used for years, and my personal favorite is Spyware Doctor. While not necessarily an AntiVirus product, it detects many trojan's and is a required product on any of my comptuers (even on employee computers).
Use AVG Free. 100x better compared to McAfee IMHO.
And less resource/cpu consumption.

AVG does the job great for us, not that we really put it to the test very often. If you know what sites not to visit and what attachments not to download you are usually pretty safe...
1. Kaspersky Anti-Virus
2. ESET NOD32 Anti-Virus
3. ZoneAlarm 2009 Anti-Virus
4. Panda Antivirus Pro 2010

I think it is safe to assume that Trend Micro is what was causing all my issues then. I think I am going to try AVG thank you for the reviews. I hadn't considered that TrendMicro was what was messing with my speed and such! UGH!
I also run Spyware Doctor on my workstation daily - I hate adware.

Just thought of another program I routinely run on my workstation weekly - Malwarebytes Anti-Malware.
