I still haven't downloaded the newest updates - is this true? I don't have a high opinion of Microsoft but I strongly doubt that MS distributes virus-infected software. Here's the Symantec worm description: W32.Welchia.B.Worm securityresponse.symantec.com (Nachi.B is one of the aliases) Welchia exploits the XP RPC vulnerability on TCP port 135. This means that if somebody goes online with a XP PC which is not patched against this vulnerability it can be infected without the usual way of infected emails or downloads. Instead the transmission occurs by a direct connection from an already infected system to the XP operating system. A friend of mine recently had a similar experience: he went online with a brand new PC, didn't patch it - and was Blaster-infected within two hours. Blaster exploits the RPC vulnerability as well.
