Possible virus??

Question

Today I was searching through my files and found a .jar file named "i left this for you.pdf". Considering it wasn't a .pdf file but in fact a .jar file, I assumed it was a virus and deleted it. Then the file reappeared in the same spot in my hard drive (This PC/New Volume (D:)). This had me extremely concerned and I do not know the origin of the file. How do I remove this file permanently? Has anyone had similar experiences?

EDIT: I have run 3 different anti-virus/anti-malware programs on this file and the programs declare it safe, but it seems way too unnatural with how I cannot delete it.

             but I cannot remove the file. 

Zachary,

Try restart your PC and boot into Safe Mode and then try to remove the file.

Also in Safe Mode, I would advise you to run <<Disk Cleanup*>>*and delete (at least) Temporary files, Offline webpages and Temporary Internet Files as this will reduce scanning times by security software – .

You may want to scan with the

RKill <<https://www.bleepingcomputer.com/download/rkill/>>

along with <<JRT (Junkware Removal Tool)>>

and finally, <<AdwCleaner>>

Start your PC in safe mode in Windows 10
