Windows 7: how to remove a malicious script

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.

Post back with your results

I'm a bit confused, how have you determined this is a malicious script? You say it is C:/Program Files (x86)/Mozilla Firefox/components/nsPlacesDBFlush.js:235

C:/Program Files (x86)/Mozilla Firefox/components/nsPlacesDBFlush.js is a legitimate name of a .js that FF installs to that location.

Navigate to that location and delete the script and replace it with this clean version.

nsPlacesDBFlush.zip

I think we need more info about your problem, and how you determined you have an altered .js file. Replace it and do the MalwareBytes scan. A Guy

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.

Does it find you have flash installed?

Can you post a screenshot of the flash test page I posted? Also, which browser were you using in the screenshot you posted?

Also, there is a flash for IE, and a flash for non IE (Firefox, Opera, etc.)

Download Flash Player 10.2.152.26 (IE) - FileHippo.com

Download Flash Player 10.2.152.26 (Non-IE) - FileHippo.com
