Sophos, a world leader in corporate anti-virus protection, today announced that Sophos Anti-Virus (3.74) has been awarded the VB 100% award in the November 2003 edition of Virus Bulletin. This is the 22nd time Sophos Anti-Virus has won a VB 100% award, confirming its position as one of the most powerful virus protection products available.

Virus-Bulletin tested 21 different anti-virus products for their detection rates, lack of false alarms and speed of scanning. Sophos outperformed a number of competing products, which missed some of the commonly encountered in-the-wild viruses.

All Sophos products use the same virus-finding engine, ensuring consistently high detection rates across all platforms.

About the Virus Bulletin 100% award The Virus Bulletin 100% awards recognise those products best able to detect viruses known to be 'in the wild'. Unlike some other similar-sounding schemes, Virus Bulletin uses the most up-to-date WildList in its tests. This means that products that are 'up with the game' are the ones most likely to be granted VB 100% awards.
