"Trojan.VBS.StartPage.bv" this virus cant be fixed by clamwin-0.93 version. this virus affect folder option and hide file extension and create a text file.It also shut down PC after a certain period of time.

Do you mean that ClamWin can not identify the virus? If that is correctn, then, if you have a copy of a file containing the virus, please go to the Clam virus submisson form at https://cgi.clamav.net/sendvirus.cgi on the Web and upload the file to them and fill out the form. They will work up a signature for the virus, and Clam and ClamWin will then be able to identify it. You will be helping to make Clam and ClamWin a better antivirus.

When it finds a virus, ClamWin can only Report, Quarantine, or Delete the file containing the virus--depending upon what you have told it to do in the General Preferences. I choose to Report--in case there is a false positive on a system file, which might kill the system if it was put in quarantine.
