how to remove a malicious script

I have a malicious script file that prevents Adobe flash from opening Youtube or browser sites that need flash to view.

This is the script file:
Script: file:///C:/Program%20Files%20(x86)/M...DBFlush.js:235

I have uninstalled IE 8 and IE9 tried Firefox. Still I have this problem.

Any help appreciated. Now have IE 8 running.

Thanks

Hello there.

Run a Malware Scan with Malwarebytes' Anti-Malware.

Malwarebytes' Anti-Malware: Malwarebytes

Boot into safe mode with networking (F8 on BIOS before startup) and perform a full scan, after done, reboot and perform another scan to ensure that every single thread is now gone.

Oh, I made an error. I uninstalled IE8 and reinstalled IE8' Firefox and back to MS8, the problem with "not being able to used Flash programs. When i try to 'see" a Youtube clip or web site, it says install Adobe flash. I do and the problem is still there as per Youtube. I just mistakenly thought that the script file was the root cause of the problem. now i guess it is a virus of some sort aimed at adobe flash programs. Still MS security and malware, nortons, JV16 did not find anything. Thank you for your insight.
