Top 6 antivirus

1 - Kaspersky - I use the internet security suite, and am able for $60 to use it on three computers without cheating
2 - Avast - For a free for home use once registered this software is great. I really like the boot time scan feature.
3 - AVG - Although not free anymore, unless you have sources, this software is good for the price.
4 - Malwarebytes - Not really sure if this should be on anti-spyware or antivirus since it does both. But this program has fixed many a computer by itself.
5 - ComboFix - You need to make sure you get this from the right place and that you know what you are doing, if not then you may cause more harm than good. Luckily it asks to install MS recovery console and creates a restore point if it does.
6 - ESET NOD32 - This is what I see the machines at school running, and I do not see many problems as far as viruses.

Please note that these are my top 6, and based upon my opinion or experience. You may have your own, and you may want to know why Symantec <aka Norton> or McAfee are not on this list. Again like a previous post, I will go into that at a later date.
