Your system probably is infected with a wild trojan horse which you invited while browsing on the web.

Please try this:

1) Browse your PC and find your "regedit.exe" file (usually in C:\Windows)
2) Right click on "regedit.exe", copy, and then paste to your desktop
3) Go to the new "regedit.exe" file on your desktop, and rename it "regedit.COM"
4) You should now be able to douleclick on that file and open Regedit


Navigate to


expand that (click on the + sign) and scroll down to ".exe" and click on it

The bar at the very bottom of the window should show that you're on the location:
My Computer\HKEY_CLASSES_ROOT\.exe

The first value for .exe should be the follwing:

Name___________________________Type _____________________________Data

If it says anything else under the data column (for example "secfile" instead of "exefile"), you need to change the value back to "exefile"

You can change it by right clicking on "(Default)", selecting "Modify", and then deleting the incorrect data, typing in "exefile" and clicking "ok"

This will renable all of your .exe files.

Once you have done this, close out of regedit and delete from the desktop so it can't be altered accidentally.

There will be cleanup that still needs to be done, but unless you're very familiar with the registry, it's best to use software.

The free version of Malwarebytes is always a good start.

Download, install and run Malwarebyte which you can find on this site: es-anti-malware

Ensure you make an update.

Boot your computer in safemode

Please request a FULL system scan, which may take from 20 minutes to hours. Do not interfere no matter how long in takes. The creators of Malwarebyte recommend that while the tool is running that you go do something else, such as watching a rerun of Gone with the Wind or read Tolstoy's War and Peace.

If Malwarebyte restarts your system, launch it again to finish the Full scan.

When the scan is completed, delete all items found.

Once your computer is clean and working normally just to be on the safe side
*Turn off system restore and wait 30 seconds,
*Turn it back on and create a new restore point.

This way it gets rid of anything bad that might have gotten saved in a restore point and you have a clean restore point to use in the near future if needed.
Do not turn it off until your computer is clean and working normally because you might need to use it if something goes wrong during the clean-up process.
It is better to go back to an infected restore point if something goes wrong then to not be able to undo changes that were damaging.

Hope this helps :)
