Malwarebytes was not updatede when you did the scan…always hit the update button before you start a scan

I’ve been out of town for a while and hadnt had time to run the scans on my mom’s computer but now I have and here are the logs. She described her computer as running pretty normally except for those popup warnings

essexboy · July 14, 2012, 11:31am

Could you run a fresh OTL scan please and let me know the current status

system · July 14, 2012, 8:00pm

Those scans were fresh from a few days ago, does the virus change that quickly? I’ll tell my mom to run the scan on her computer, do you want it to use the same custom fix code you gave me before?

Also she says her computer is running a little bit better than a few weeks ago but the pop up errors still bugging her

essexboy · July 14, 2012, 9:31pm

Yes please, also what are the popups ?

system · July 15, 2012, 9:07pm

Heres a fresh OTL scan. The pop ups arent ads or anything its the messages from Avast saying that it blocked a Trojan and another one saying it blocked a rootkit happening every 3 mins. They both say its coming from services.exe

essexboy · July 15, 2012, 9:33pm

Yep sirfef is back
