hahaha ... seriously if you keep your defence active which includes AV programs with up to date definitions, adware, spyware utilities, etc. then you should be ok. See
WARNING: Viruses on network you should be aware of! where you'll see a link to many of these utilities which are FREE & also some free AV programs. There's a few viruses reported in that link. But considering that's all that's been reported, that's not too bad considering how many viruses, etc. are out there. Everybody needs to keep their guard up against such things.
