Hello friends. My first posting tonight - usually my computer works well for me so I have never had to seek help.

I have come down with 1 virus that is very apparent - Malware Defense Virus is what I call it. It appears to be an unregistered Microsoft product that has found ten or twenty viruses on my PC and asks that I register and pay for the product. It prevents me from running McAfee or Norton in regular mode (Safe mode runs fine from command line and does not find anything) - the services/applications won't start.

Additionally, there appear to be a number of trojan horses and viruses that constantly pop up in Microsoft Security Center Alert. They are listed below:

McAffee's online free scanner found the Malware Defense files in C:\Program Files\Malware Defense (3 to 5 files), but did not find any of the other infected files associated with the list of viruses and trojan horses above.

It appears that 2 iexplorer.exe processes run even after I stop them in taskmgr. Additionally I have stopped/disabled a number of services that don't seem to doing much to try to isolate these viruses. I can restart them as needed.

Taskmgr will not start from te control/alt/delete window - instead I need to start it from the command prompt.

Please advise on how I should proceed.

Thank you!

So I made progress by getting rid of the Malware Defense virus/trojan horse by reading through the common malware issues and remedies on the homepage of this discussion board. However, now I am having issues getting Norton Antivirus to start up, run a complete scan without freezing and start up when I boot the computer up. My sense is that something is disabling it or has messed with the exe files so that it won't start up.

Since I was able to install Malwarebytes Anti Malware, I can run that scan after running rkill (provided in the Malware Defense fix) and it finds two issues repeatedly: Rootkit.TDSS and Trojan.DNSChanger. Does this mean I keep getting reinfected by these viruses after they are quarantined and deleted by the Malwarebytes Anti Malware?

Could not wait for a response as time is critical for me here, so I searched on Trojan.DNSChanger and Rootkit.TDSS in the forum and found instructions to go into safe mode and run ATFCleaner and SuperAntiSpyware, which I did. Here is the log file from SuperAntiSpyware:

Happy New Year friends! The problems are not solved - none of the antivirus software gets rid of the problems and after a reboot or two the anitvirus software won't work (except MBAW after running Rkill). When I log in regular the desktop does not come up unless I hit Ctl-Alt-Del immediatly after logging in. Task Manager does not start from the Ctrl-Alt-Del box, only from the command prompt. Please let me know if you have any ideas or suggestions on how I can solicit a response (am I being ignored?) Thank you.
