Helping a friend try to clean her computer and it's the most generically infected machine I've seen in a while.
It is a eMachine EL1852G running Windows 7 Home Premium.
Upon booting it up, it had the usual suspects, Optimzer Pro, SpeedUpMyComputer, etc. and her 2 browsers (IE and Chrome) both opened to the Trovi "search" page.
I've managed to remove the bulk of the spyware/adware and infections and after resetting the Proxy settings, I'm back online and all three browsers (I installed Firefox) are up and running with no pop-ups and/or redirects. I checked all three browsers for extensions/add-ons and have removed and/or disabled all of the ones that were there.
Initially I ran a Full Scan from MBAM (Free) which found well over 20 infections and a bunch of PUP's and PUM's. A couple of reboots later and things started getting better.
I removed all the other out-dated AVs that were on there and installed Avast (Free) which ran it's Quick Scan. That found several other items and also recommended running a Boot Time scan, which I did (moving everything to the Chest) and that helped also.
After that I ran another Full Scan with MBAM and that found less items than the first scan, but I was startled to find that there were still infected items on the computer.
As it stands now, I've run another Full Scan with Avast which came up with a "some files could not be scanned" message and currently my Chest is chock full o' items.
I also went ahead and ran my 3rd Threat Scan with MBAM, which came up with a message "656 non-Malware Items detected."
Each time I run MBAM it seems to be coming up with less and less items but they are still there, so...
I was going to go ahead and also run the ESET Online Scanner, but at this point it feels like I'm in the weeds and need to reach out to the Professionals.
Another item to note, the machine itself is running fine (not slow) and as I mentioned previously, all three browsers are not redirecting or subject to the pop-ups.
So, there you go.
My guess is that I need some more investigation and possibly some deep cleaning but do not know where to start.
I'll be in and out all day and work in the afternoon, so if I don't get back to you today, I'll be back logged in early tomorrow morning (U.S. Eastern Seaboard Time).
