Hello, My wife has infected her laptop (Windows7 Home Premium 64 bit) with Win64/Sirefef.Y I've seen several other topics regarding this issue. In my case, I cannot get the computer to stop automatically restarting once logged in. I've tried normal startup, last known good configuration, and in safe mode (with and without networking). At this point it appears I need to create some sort of CD/DVD/Flash drive boot disk but I'm not sure how to proceed. I'd really appreciate any help I could get. Thanks in advance!
