That is the troubling part for me, that's way too long for a newer machine imho.
TDSSKiller is a very fast running scan, takes less than 5 minutes on my old clunker.
Good to hear that it found nothing because I was suspecting a *root kit* virus screwing up the registry.
Maybe you need more RAM memory, but I think 3 Gb just running Malwarebytes should be adequate and not require 7 hours of run time.
I’m still not sure what’s wrong. There is clearly a lot of junk in the system, as I was observing the scan. The problem, too, is that the computer is acting no different than before. The slow loads, the getting knocked off log-ins. I had to borrow the old computer (which has its own problems and is almost 5 years old) and the websites were loading like lightning by comparison (although the substantial downside is that it has a nasty habit of “blacking out” while in the middle of doing something — and the history cache from the time it was turned on, all logged-in websites, are dumped from the memory. This was one reason I stopped using it in favor of the newer computer in the past several months). If it costs more than a few hundred bucks to correct the problems, it’s simply better off buying a new machine.
