If you're currently trialing the latest public BETA of Windows 7 and want some good anti-virus support specifically suited to it, Kaspersky have just released a new anti-virus suite for it which although is described as a "Technical Prototype", is promised to be a reliable fully functional piece of software which is built on a completely new anti-viral engine.

Kaspersky Lab's technical preview is a comprehensive solution, including not only an antivirus pattern-recognition component but also a heuristic analyzer which can detect and block as-yet-unknown malicious programs based on their suspicious characteristics, a firewall and an anti-spam filter. The prototype is intended to provide effective protection from all types of Internet threats - viruses, worms, Trojans, spyware, hacker attacks and spam.

Further information about it can be found within the official PR here. You can download a copy of it for both 32 and 64-bit variants of the Windows 7 BETA here.
