PC Tools detects but cannot get rid of the Tdss virus. I have run the scan in normal mode and safe mode with networking.

It shows the threat as Rootkit.TDSS!sd6 and claims to block the problem every 10-20 minutes. Neither IE or Mozilla will function properly. The following is the activity history in PC Tools. I am using the most current version of PC Tools with Antivirus.

All of the system event blocked messages refer to the same threat with the same information at the bottom.

I have downloaded Malwarebytes Anti-Malware and installed it, but it will not open for use. It may not have installed properly. I assume this is due to the infection.

Additional info:

Internet Explorer is the main browser I use and is not working properly due to infection. Mozilla is also not working. Netscape is currently working correctly.
Window XP service pack 3
currently running Windows Firewall
was infected with Virtumode about a month ago, supposedly PC Tools fixed that. (that is when i started using PC Tools) I have had no real problems between the Virtumode infection and just a few days ago when this problem started.

Not sure what other information you need.

You might try renaming mbam.exe in

C:\Program Files\Malwarebytes' Anti-Malware
Chewy

No. Try not. Do... or do not. There is no try.

Just tossing in some more ideas.
Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the

.exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above.

Then double-click on it to run..


***
Another work around is by not using the mouse to install it, Just use the arrow keys, tab, and enter keys.

I renamed the files as you suggested and was able to run MBAM. It found and cleared 23 infected files. Thank you for your help.
