Yesterday I went to the site supposedly operated by the gov't to scan computers for the dns hijacker malware, and my system hasn't functioned properly since. Has anyone else experienced any problems after going to that site? I can't access my hard drive in regular Windows mode (XP, SP3) but everything seems to be functioning in safe mode. I did a scan for malware, went into msconfig and disabled all the extraneous start-up items, and did a system restore, and still no progress. Any suggestions would be welcome.
If you have the installation disc, you can run "SFC /SCANNOW" with disc inserted. It will look for and replace/add damaged/missing files. Also you can check Services in msconfig, hide all Microsoft services and sift through the remains. Then you can run services.msc and look for services belonging to a particular software, stop and disable when found. Run CCleaner and uninstall the malicious software, add the Documents and Settings\<user name>\Local Settings\Temp, Temp Internet Files, History folders to cleanup.
I do a lot of gaming and I replaced my Avast with Comodo. AVG is easily disabled by porn websites.
Otherwise, you can run a secondary install of windows, to keep or backup files and data, then reformat and reinstall windows if all else failed.
