However one of them seems to have been my winlogon.exe
Google redirect virus tend to infect the driver files in computer and there is no definitive answer to this problem. in my case, atapi.sys file was infected and as soon as the infection was killed using tdss killer, my search results stop redirecting. Also check dns settings, proxy and host file. This virus is now spreading in new ways and my all antivirus software failed to detect it. I was able to follow this Google Redirect Virus Removal method and got rid of the problem.
I'm willing to buy mcafee If it can deal with such problems. can anybody confirm this for me?
