Try "Malwarebytes" - Anti-Malware, you can download it for free. This cleared up my problems...and I had some nasty stuff.
If a program was downloaded on your computer, you might have to manually remove it from "add/remove programs" in your control panel.
I usually get my problems checking sigs on GYF, it seem their website is safe, but once you start clicking on their Photo Galleries..."it's like a box of chocolates...you don't know what your going to get." The pain in the ass spyware/virus lately is a PDF pop up...you just visit the infected website and it just pops up. I avoided it a couple more times by quickly hitting CTL ATL DELETE...and ending the process.
Hope this helps...
