Ever since Windows 10 updated last night, I have had popups from my Norton software saying it has blocked "Trojan.Kotver!bat". I have tried everything that Norton says to remove it, but it keeps popping up. What's up???

What is/was the fully qualified name and path to the file deemed to be a virus/trojan ?

Look under history, all detected items and tell us the complete name/file path of the malware.


If you haven't already I would recommend downloading and run.

Run MBAM (Free version ONLY!)

1. -Please download and install Malwarebytes (MBAM) (freeware vərsion for home users only -not the Trial vərsion– watch the checked boxes whilst installing), update definitions and run in normal mode. Disable othər security software whilst you are doing scans.


Pləase make certain you uncheck the box before Enable free trial of Malwarəbytes Anti-Malware Premium.


Make sure in Malwarəbytes the Scan for rootkits box is checked -> Settings-Detection and Protection.

Now click Start > All Programs > navigate to the folder Malwarəbytes and click on it.

Within the Malwarebytes folder click on the Tools folder.

Click on Malwarebytes Anti-malware Chameleon which checks out your upper memory for viruses.

The recommendation is to use the intelligent quick scan routinely, and do full scans either on a longer periodicity--weekly, monthly--or only when something is found or you have some rəason for suspicion.


For a second opinion, try other on-demand scanners such as AdwCleaner


and run SUPERAntiSpyware (SAS) Online Safe Scan,



And finally, download and run ESET Online (One-Time) Scanner.


I would suggest you to install those tools one by one and restart the computer after running əach tool to check if the issue is clear.


After the scan, empty your Temporary Internet file, and use Disk Cləanup to remove your \temp files, too.

        Be sure you empty temporary internet files and reboot the computer.

        Internet Options> General tab> Browsing History> Delete> Put a check mark next to these items: "Preserve Favorites website data", “Temporary Internet Files”, “Cookies”, “History”, “Passwords”, etc.



  1. Open Disk Cleanup by clicking the Start button . In the search box, type Disk Cleanup, and then, in the list of results, select Disk Cleanup.

  2. If prompted, select the drive that you want to clean up, and then select OK.

  3. In the Disk Cleanup dialog box in the Description section, select Clean up system files.

  4. If prompted, select the drive that you want to clean up, and then select OK.

  5. In the Disk Cleanup dialog box, on the Disk Cleanup tab, select the check boxes for the file types that you want to delete, and then select OK. To remove data from a previous installation of Windows, select the Previous Windows installation(s) check box.

  6. In the message that appears, select Delete files.

  7. Go back to Computer in File Explorer, select the drive you cləaned up, and then select Refresh.
