We have 3 computers on a wireless network, so I scanned mine with AdAware, SpyBot S&D, and AVG 7.1, all of which produced clean results. Then I downloaded the free version of Spyware Doctor 4.0, and it returned 82 infections, of which several were high threats. The most disconcerting to me were Trojan.Dumaru, DSS Agent, and Bargain Buddy. Are these actually malware, are they real threats, and why didn't the other programs catch them? I am considering purchasing the full version of Spy Doctor to fix the infections, but something doesn't feel right about this. I also ran Hijack This v1.99.1, but the results are jibberish to me. I haven't been having major issues with my computer, so I'm not sure what to think...
I appreciate any advice you can offer.
