My laptop computer was attacted by amvo.exe (together with amvo0.dll). I tried to follow the steps from http://digitalpbk.blogspot.com/2008/02/amvoexe-virus-usb-memory-stick.html, but everytime the virus just come back. In one of the step above, i was supposed to install the sw from www.bpftp.com, to list all the hidden files. Using the sw from bpfpt, i can find amvo.exe and amvo0.dll. I can delete the amvo.exe, but cannot delete amvo0.dll. Does anyone knows better way to remove with amvo.exe ? How to prevent the viurs from coming back ?
