Located in beta version and free to download (free. For tests), Windows 7 seems to have attracted the attention of companies producing software anti-virus, who want to prepare in advance for the launch of the final version.
In principle on Windows 7 should work all programs that are compatible on Windows VistaHowever, three anti-virus companies have already prepared software dedicated to the new operating system.
1. Of course the first anti-virus program compatible on Windows 7 is Norton 360 3.0 Beta. I would not recommend this anti-virus to anyone. I have old sequels tied to Norton. You can download this product after filling in the form from the address here: download Norton.

2. without doubt AVG is one of the most popular anti-virus programs used on Windows XP. It seems he does not want to lose any user and brings two products for Windows 7. AVG Anti-Virus and AVG Internet Security (with built-in firewall and anti-spam protection).

3. Kaspersky Lab have announced the launch of an anti-virus prototype for Windows 7. Kaspersky anti-virus 7 promises to be much more efficient in combating viruses than its predecessors. Careful scanning of files, increased scan speed and “Heuristic Analyzer” Improved are just a few new Kasperky Lab novels for Windows 7 users.
