Hello helpful people!
Please bear with me, I know little about computers. I'm writing about a laptop that is a Dell with Windows 7/64 bit. It seems that my system has some type of virus in it. Last week I ran a full scan with my McAfee Security Center since I had noticed that it hadn't updated in a while and I found a Trojan and it quarantined it. Then after I deleted it when I rebooted there it was again in the quarantine folder but from a different location and file. This happened three times. After I deleted the Trojans (I thought) and rebooted there was another one with a slightly different numerical sequence (same first letters FCMG!) and it appeared under two separate locations and files as well (System files: C:\Windows/Sys\WOW64\TrustedInstaller.exe and also C:\ProgramFiles\HijackThis). So I deleted those trojans from the quarantine folder. When I rebooted after that nothing shows up in the McAfee quarantine folder anymore.
However though my computer runs fine and I can use it I'm concerned that I may have spyware or something in there and it's only a matter of time before things will get worse. I can no longer update windows or use the action center on my Dell. The buttons on the Control Panel page don't work when you click on them individually and I am limited as to how much I can scan the system. The windows defender doesn't work, PDF or Word preview doesn't work in Outlook.When I do sfc /scannow it goes through the verification phase and then says everything is fine. The Dell Center Scan showed everything passing. And when I reboot the computer now McAfee shows nothing in the quarantine folder and the full scan shows no infected files. Still I cannot use Windows Update or click on other system links in the control panel.
I also noticed today when I looked at some event logs in the safe mode a MediaFACE installer (MsiInstaller) that had tried to change registry settings in the system around the time of the trojan discoveries many times over. Don't know if this is anything but I do remember a box asking me about MediaFACE as I was dealing with removing the trojans. Since I had MediaFACE I thought it was an update and clicked on it. Is that something?
Can anyone please help with this?
Thanks so much!!
