Okay... the porn pop-ups are a pretty sure sign of infection.
I would recommend going to the
virus and malware removal forum, and carefully read the four stickies at the top.
After doing so, if you decide to proceed, please follow
the 8-steps carefully, before making your post there.
By the way, Spybot alone is not enough security.
The team there will help you get secured, with top notch (and free) security software.
Meanwhile, may I suggest that you have your friend take immediate steps to secure her business affairs.
The reason I say this is, much malware today is designed to covertly steal logins and passwords, focusing especially on banking information.
If your friend has done
any business on line, her accounts should be considered "at risk" and all log-in's and passwords changed.
Please note also... one of the worst vectors for malware today is file-sharing... including music, but also "warez/cracks/etc".
Torrents sites and music sharing sites are notorious in the anti-malware field.
This may well be the source of the apparent infection.
Note also, malware is capable of hiding in your "restore to an earlier date" mechanism, as well as other places.
At this point, my bet is, when the malware issue is resolved, most other problems will be as well.
If you still have things you want to address after you are through in the malware forum, come back and repost.
I will be notified when you do.
