This was confirmed by Microsoft after a report by Sophos (UK). The US software group also said that, in fact, they have not been able to do anything with viruses like Stratio.Zip, Netsky.D and MyDoom.O because they use social engineering to trick the computer.

The three viruses alone account for 39.7% of the total number of malicious software currently distributed, Sophos noted.

' Based on preliminary investigations, we confirm that the Stratio.Zip, Netsky.D and MyDoom variants do not attack by taking advantage of a software vulnerability that spreads in a way that deceives users as a distribution agent. ', a Microsoft text wrote. Sophos said Vista's built-in Windows Mail Client system could block all of the top 10 viruses in the list they recorded in November, but the three viruses could spread when the computer used the part. 3rd party mail browsing software Stratio.Zip is the most dangerous virus of last month according to Sophos statistics, accounting for 1/3 of the total malicious code.

British security firm also said there are currently no specific viruses targeted at Vista, but they will soon appear, either completely new or modified from older variants. 'For example, Stratio.Zip is constantly being revised code and therefore always ranked No. 1 in terms of dispersion, and making prevention systems constantly updated to detect changes.' Sophos expert Ron O'Brien said.

Windows Vista was officially released for businesses on November 30, but so far only two Sophos and McAfee have antivirus software specifically designed for Microsoft's new operating system, while other big names like Symantec, TrendMicro and CA are still under construction.
