Trojan.Kovter found


Recommended Posts

Hey, good afternoon.

I have some concerns about a Trojan that a recent scan with Malwarebytes found in my system, I've attached the log from the scan to my post for reference. I'm not sure if this is the actual Trojan or just a false positive.

It seems that a file in my download folder contained to the Trojan Kovter, which has me extremely worried that I've been infected. I have scanned an additional time after it has been quarantined and it has not returned as of yet. My PC is also not displaying any obvious symptoms of being infected as of right now. I am aware that this is an extremely difficult Trojan to remove and did end up using Syamatec's removal tool just in case, but the tool gave me the "Trojan.Kovter has not been found on your computer" message.

What are the next steps I can take to ensure that the Trojan is fully gone? As a precaution, I've already changed all of my passwords.

Thanks.

While I was in the middle of applying the fix with FRST, my monitor shut off like it had fallen asleep. But any attempts to wake it back up haven't worked, I can still hear my hard drive working inside my PC tower, so it's obviously still running.

I don't feel safe shutting it off, what should I do?

Thanks for those logs, if no remaining issues or concerns lets clean up:

Download and run the following to uninstall Zemana and Sophos AV:

Download GeekUninstaller from here: http://www.geekuninstaller.com/download (Choose free version) Save Geek.zip to your Desktop. (Visit the Home page at that link for necessary information)

Extract Geek Uninstaller and save to your Desktop. There is no need to install, the executable is portable and can also be run from a USB if required.

Run the tool, the main GUI will populate with installed programs list,

Left click on Program name to highlight that entry.

Select Action from the Menu bar, then Uninstall from there follow the prompts.

If Uninstall fails open the "Action" menu one more time and use "Force Removal" option

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…
