After several hours of trying, I think I got Spyware Doctor 2010 to remove these trojans. However, I faced some re-start issues after that (blue screen on restarting PC). I ran the Spyware Doctor Full Scan a few times and tried disabling Spyware Doctor Automatic start-up while booting the PC...and was somehow able to overcome the re-start issue. (was unable to start up the PC in Safe Mode no matter how many times I tried).
Right now, I ran the Vvundo Fix, Spyware Doctor, Eusing Registry Fix and TFC they all return NO malware/virus errors. However, the two problems I am facing are -
1) Malwarebytes still will not launch. I tried the trick of changing the name of the installation .exe as well as the application file name. However, the software still does not launch and I get a "mbam.exe file not found" error inspite of renaming the file.
2) Internet Explorer does not launch. i tried re-installing, however IE crashes immediately on launching sometimes with the "memory not read" error.
Because of the above, I am nervous that there are some remnants of the Trojan that are still lying around and might become active again. I am able to connect to the Internet and Wireless without any issues.
I will appreciate any guidance you could give on this.
