I have a really strange one here that I hope you can help me with. I just bought this Dell M5110 laptop that has W7 64 bit. It seemed to be working ok and I went ahead and put all of the minor programs I want in it and I added AVG antivirus and Zone Alarm firewall. I had done some maintenance tasks also. I use downloads only from where I have gotten these before and am careful. The only thing that may be likely suspect is a program called OfficeAdRemover. I have uninstalled it but it may have left changes of course. Somewhere along the line it seemed to get kind of lame in its response. I thought wow I guess some of these programs I use must be slowing it up. Then when I tried to check and do windows update pretty soon I started getting processe(s) with max ram usage and it would nearly freeze up. Sometimes this starts right from startup, sometimes it takes opening a browser. Checking for windows updates always starts the svchost appetite.
I tried to find out why something in one of the svchost processes would go crazy and I also started doing virus/malware scans. Ultimately I came to the conclusion that it has contracted something as it is doing some of the really strange actions like erratic operation, no or slow response and even the internet connection being stopped at times.
Since the problem started I have run Malwarebytes scan, Superantispyware scan, AVG scan, ESETand MS security scanner, Adwcleaner, JRT, Rkill and TDSSKiller. Some things that seemed minor were found but nothing ever helped.
I have had two other groups look at this. One seemed to think that it was not infected and seemed upset that I had tried combofix several times with no results. I think that since this may not be an “easy” one they give up. The last “tech’s” statement was that it was a low power, small ram laptop and “it is inevitable to choke sometimes.” Running up the svchost to near freeze up when there is not even any browsers open and just sitting on the desktop doesn’t seem like “choking sometimes”. This acts exactly how other pc’s have acted with malware.
Do you have a scan or other investigations I can do to fix this? Thanks for any help.
