I have only been using my new Windows 8 computer for a couple of weeks and now it appears to have a very serious virus. Windows security essentials continually detects a problem which it says it quarantines and removes, but it doesn't seem to actually work as the alert keeps coming up every couple of minutes. I've tried running scans on Malwarebytes, and it finds the Sisrefef virus. It removes it then says it has to restart the computer. After I've restarted the virus appears to be back. It seems to be affecting my Internet connection as well. Sometimes it says I'm connected and Internet just doesn't work, other times it disconnects me frequently, other times it just says there are no networks. Or the Wi-Fi doesn't work at all.

I would use the recovery disks but all my files are on the computer and I'm afraid of losing them. I have them on a separate partition on the same laptop, but I'm not sure if it will be affected or not.

Please help!

Before I got your response, I tried restoring the computer to a previous time. It caused the computer to go all weird on me, and the wifi stopped working entirely. After another restore attempt, the whole computer crashed, and continued crashing with a blue screen over and over and over, sometimes before I could even log in. I decided to do a restore from the factory discs I made when I got the computer. Now it went through the whole recovery proces (6 discs) and says it was not successful. So I am trying it again a second time... if this doesn't work I am going to be very mad!
