This is my aunt's computer, so I don't know all that details behind what's on it. (I don't remember iExplore, MBAM or COMOD being on the PC when I used it on Tuesday.)
It appears that she caught something (it appears to be Antivirus Scan based on the new bookmarks). It looks like she followed some instructions, used iExplore, then scanned with MBAM. But it still has the problem with Google links being redirected, and random tabs opening with ads or saying "Download Registry Cleaner". This is happening while using Firefox, as Internet Explorer is not used. It also looks like she downloaded COMODO Internet Security Premium after she used MBAM and Iexplore.
I ran MBAM again today and the results said nothing is infected. Here is the top part:
Malwarebytes' Anti-Malware 18.104.22.1680
Database version: 5604
Windows 5.1.2600 Service Pack 3
Internet Explorer 8.0.6001.18702
Hopefully this is enough to begin the helping process. I appreciate any and all help.
