Hello. Last Thursday I was infected with what Symantec called a Trojan.Gen.2. Since that time my computer has been slow and crashing. I have run symantec and Avast and Malawarebytesa among others but they are all coming up clean. MBAM keeps blocking ingoing and outgoing IP's of malicious sites. Neither GMER or DDS will run properly. DDS doesn't complete within 3 minutes and GMER options are greyed out. Please help.
