Virus versions

Hello,

I know I have asked this question before, however, due to certain new issues I would like to find out again from you which option is the best.

I have three(3) antivirus softwares:

- Mcafee enterprise 8.5
- Panda 2008
- Kaperskey 6.0.2.614

The issue I have is that I currently use the Kapersky 6.0.2.614. However, I don't have Internet access and the latest date of the Kapersky signature dates is 1/29/2007.

I assume this means its the 2007 version.

I regulary download images and pdf files and web filesfrom the Net for studies and pleasure.
I am worried cause I think my antivirus may not be of a good standard. I know you said that Kapersky was the best of my options but do you still think that it is so after my explanations.

Please comment on this quickly cause I need your assistance since I currently download picture files and pdf fils often.
