Laptop running too slow with Avast antivirus
Avast antivirus is running with my laptop. The current configuration of my laptop is 64-bit Windows 7 Home. It has been serving for a long time without any problem, but at present, there is a problem with my laptop. It is running slow. I scanned fully with Avast and found a DLL file. It found several files, but whenever it has to delete them, it throws an error message regarding running that file with other programs. I think, I need to delete those corrupted files for fast operation of my laptop.
An error message regarding this issue is given below:
Can anyone help me?
Thank you so much.
