Sophos finds three of top 10 malware threats can bypass Vista security
Security firm Sophos says three of the top ten malware threats in November are capable of bypassing Microsoft's Windows Vista's security defences and infecting users' PCs. The Vista-resistant malware - Stratio-Zip, Netsky-D and MyDoom-O - comprise 39.7 per cent of all malware currently circulating.
Sophos tested each piece of malware in the top ten on the operating system that was released yesterday, to establish whether users running Vista without any third-party security software would avoid infection.
The results showed that while the Windows Mail email client (Vista's upgrade of Outlook) could identify and halt all of the threats, Stratio-Zip, Netsky-D and MyDoom-O - each of which are commonly disseminated via email - were able to bypass the defences when accessed via a third-party web email client.
