can anyone figure it out..
I'm using Mozilla Thunderbird 1.5.0.4, a couple of days back I noticed that all attachment like *.doc *.xls got changed to *.bin *.dat after they were sent to a recipient.. Avast scan found Win32:Sality-W in updater.exe file, but couldn't remove it. Currently none of the virus scanners, including avast, can find anything... however the problem still exist..
any idea what's up
