Press Ctrl + Alt + Del, click processes and see if any processes are there that are abnormal. If so close them down, if no more pop-ups etc open, then go

Start --> Run --> type "msconfig" no "", and click startup and remove the entries that refer to those process(s) being run. Be careful, and if you don't feel confident/ haven't done this before then don't do it.

Note that is, only a shortterm solution.. it should stop it happening but the files will still be on your computer.

Also, if you've installed anything lately i'd suggest uninstalling that, or even using system restore to restore your system to a date before this started happening.
