I just downloaded Windows defender after battling all weekend to rid my system of a Malware trojan that my up to date McAfee Antivirus found, but would not fully clean as I'd rebouut, rescan and there it was again. I went through the painfully time consuming removal process described at: http://forums.mcafeehelp.com/showthread.php?t=227241 including having to rename everything before running the suggested packages. I was 99.9% sure it worked because I rebooted, and a McAfee scan founnd nothing, and mu browsers behaved as expected. This trojan would redirect you to random links after clicking on a link from a Google Search and I had none of that. Less than 30 seconds after starting my first Windows Defender Scan, Mcafee finds the same trojan, and it says it found it in winidows defender. Details: Name: c:\windows\system32\gaopdxardpayglmkuoecuirmayoeyquqkqrimh.dll In Folder: c:\windows\system32 Source: Detected As: DNSChanger.r Detection Type: Trojan Status: Cleaned (but I doubt it) Date ant Time: 4/9/2009 10:55:01 Application:C:\Program Files\Windows Defender\MsMpEng.exe Username: NT AUTHORITY\System Client ID:0(my pc name) Any thoughts as to what might be going on?
