Title: Win32/Sirefef on my PC
Post by: japhillips on July 30, 2012, 04:30:46 PM
Hello, I am new to this form. My computer too is infected with the win32. Alerts kept popping up, I have ran malware scanners and removed it but it keeps coming back.

 I have downloaded Combofix but have not run it because I dont want to do any additional damage? Any help would be appreciated

Thanks

At the moment no.. I have seen all infected, but and here is the bonus.. Avast blocks it and lets you know until you get it fixed..  Several AV's just report on boot.  Then if you do not reboot for a week it has a wonderfull time doing its thing
