What is Win32/Sirefef.EV? How do i remove it from my computer?

Win32/Sirefef.EV is a dangerous Trojan horse detected by MSE or NOD 32 ESET. Once your computer has contracted with this virus, so after one day or two, and not long after seeing your computer slow down then many users ran online antivirus as per the virus removal guide and found nothing. You have Kaspersky installed and it didn’t detect anything until recently where it showed: “Generic Host process for win32 services is trying to access malicious software. Trojan programs: Trojan.win32.small.bmph and Win32/Sirefef.EV”. It showed users the same message for two other Trojans: trojan.win32.small.bmpi and trojan.win32.zapchast.acao. At that time the avp.exe process associated with Kaspersky was running at 99% CPU making it extremely difficult to run the tools on user’s computers. Win32/Sirefef.EV might spread from some false webpages, and an expected file attachment could still be infected with a virus, without the sender knowing it. You will need to deal with such annoying issue to keep your computer free of viruses.
