May have been infected with Firefox Patch js


Recommended Posts

Hello, yesterday while on a website a popup came up saying urgent Firefox patch.  Normally I don't click on things like that, but I foolishly did, downloaded the .js file, clicked save which at first appeared to do nothing, then Adobe Dreamweaver opened with some kind of text on it, which I didn't take time to read, I closed it wondering why it had opened.  I soon had an uneasy feeling so started researching and learning that javascript files are being used now to infect computers.  I deleted the downloaded file, did a system restore, went back to about a week before, uninstalled Java, found another site where it said to remove suspicious add ons in Firefox, checked for files it said to check for and suspicious changes in the registry that it had listed.  I didn't find anything out of the ordinary.  Also ran scans of Malwarebytes, Spybot.  which found a few minor things, but didn't find anything relating to it.  I had started a scan with Eset, which is still ongoing and paused for now, it indicated it found a couple of things, I don't know what yet.  In the meantime I wanted to check further.  Thanks for your help.  I have attached the scans as mentioned.

I did a clean install and updated Malwarebytes, ran the scan per instructions, it found 0 threats.

Then I installed AdwCleaner and it found 13 threats.  Not sure how serious they were, but I cleaned them all.  Some are related to a program I installed, but don't really use any more any way.  I have attached the logs.

I tried to install Sophos, but kept running into error 1327 invalid Drive I:\ and couldn't install it.  Not sure of the problem, might have something to do with mapping drives?  Tried the SUBST command in the command prompt, but made no difference.  I have no idea what drive I would be.  I'll keep researching that, in the meantime thought I would post the logs.  Thanks again.

When I download from the link, I'm not given an option which drive to install it on.  It downloads, then when I click on it, the only option is 'Run' and then I get the error message.  I'll try it with a different browser or see if I can figure out somehow to get it to install on C:, I have no idea why an 'invalid' I drive comes up as an error.  Thanks.

Hello phgray,

If your PC is responding as expected and you have no remaining issues or concerns continue as follows to clean up....

Uninstall Sophos AV http://www.askvg.com/how-to-completely-uninstall-remove-a-software-program-in-windows-without-using-3rd-party-software/

Next,

Download "Delfix by Xplode" and save it to your desktop.

Or use the following if first link is down:

"Delfix link mirror"

If your security program alerts to Delfix either, accept the alert or turn your security off.

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

Make Sure the following items are checked:

 
  • Remove disinfection tools <----- this will remove tools we have used.
  • Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created.
  • Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection


Now click on "Run" and wait patiently until the tool has completed.

The tool will create a log when it has completed. We don't need you to post this.

Any remnant files/logs from tools we have used can be deleted…
