The computer was slow, so I started Task Manager to see if something was draining the resources. An svchost.exe process was maxing out the resources. I installed and ran CCleaner, Super Antispyware, and Malwarebytes. Super AntiSpyware found Trojan.Agent/Gen-Iexplore(fake), and Trojan.Agent/Gen-PEC. Malwarebytes didn't find anything. I rebooted after each process and nothing changed, still slow, still high memory usage by svchost.exe. Stopping the svchost.exe process solves the problem of high memory use, but it comes back when rebooted.
I recalled hearing about HijackThis, so I signed up for an account and downloaded the program. I ran a scan and got an error message - "...your system denied write access to Hosts file...click Start, Run and type: notepad C:Windows\System32\drivers\etc\hosts...delete these lines...". There were no matching lines to delete, so that didn't fix the error. I seen the fix for Vista - "...right click and run as Administrator". I right clicked and there was no option to select "Run as Administrator."
I went back to Hijackthis home page and read through tutorials and tried some of the other suggestions. One suggestion was to run "sfc /scannow" which I did and it found errors that couldn't be fixed because of corrupt files. I tried to look at the log but couldn't because "access was denied."
What can I do next?
Thanks for your help,
