Hi SDur,


Have you made any recent changes on the system?


Method 1:

I would suggest you to rebuild your icon cache by following the steps below.

Before you start rebuilding your icon cache, I’d suggest you to unhide the system files by visiting the link below.

a. Open Folder Options by clicking the Start button, clicking Control Panel, clicking Appearance and Personalization, and then clicking Folder Options.

b. Click the View tab.

c. Under Advanced settings, click Show hidden files and folders, and then click uncheck the options Hide extension for known file types and Hide protected operating system files (recommended).

d. Click on Apply and Ok.

How to rebuild Icon cache?

a. Click on Start; in the start search, type the following.

Go to C:\Users\Owner\AppData\Local folder

b. Delete the hidden IconCache.db file.

Close all the windows and restart the computer.


Method 2:

You may also refer to the following article and check:

When you run an .exe file on a Windows Vista-based or Windows 7-based computer, the file may start a different program.


Method 3:

You may also refer to the following article to run the Microsoft Safety Scanner and perform a full scan on your computer.

Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.
