how to remove a malicious script

[dendingo]

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 Files (x86)/Mozilla Firefox/components/nsPlacesDBFlush.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.

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.

Go to this site:

Find Flash Player version

Does it find you have flash installed?

Here is a copy of what happens on a website:

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

Thanks for help. See you tomorrow. I had better go upstairs and join my wife to watch a DVD. It is 7:20pm here in Brisbane. (Sunday).

OK, the Flash page does not show you have flash installed. When you try to install, does the installation complete and say it was successful? Because indeed it doesn't appear that Flash is installed. Were you doing the online install? If so, d/l the 2 files I posted from Filehippo, and run both one after the other and let me know if that flash page still doesn't detect flash, you should get a confirmation:



Also, again, do both FF and IE give the same result when testing ion the flash page?

I've been through this issue before when i was using XP back then. I followed the instructions HERE. Well it worked for me at least. You should give it a try.

I'm just curious as to what version of Java you have. Look in Programs and Features. The lastest is JRE 6U24

Copy Of Flash Player install from Adobe Site

Thanks . Here is the copy of the page:

Sorry i forgot (old age)! Running IE8

Hi All,

I tried to view Youtube and a webpage catalogs using MS IE8 32bit. Yes it works. So my problem is/was with the 64bit Adobe Flash (?). With luck the 64bit Flash will work before we have Win 128 bit!!

Again thank you all.

Adobe Labs - Adobe Flash Player "Square"

This in reference to browsers not the OS. The OS has to be 64bit to have this to begin with. Which yours is 64bit according to your specs.
You need the Flash square for 64bit browsers. This works with IE9 I'm not sure about IE8 64bit.

It is a bit confusing with I beleive 4 different versions of Flash to know which you need.

Thanks Mike,

All was well for a while, then being a bit careless, I had a popup saying update adobe flash. In a flash (a pun) I clicked the popup and too late it was not from Adobe. I do have a recollection that I did indeed download the 64bit flash from a non adobe site. Now I have reverted to IE8 32bit and all is well. It is frustrating to revert to a lesser system but there you are. I did dl IE 9 and had the same problem. I feel it is with Flash not intergrating (64bit).

Thank you for your response.
