Hi,


Whenever I open an MS Office application (Word, Excel, etc.) a few command prompts open and close rapidly, one after another. The title bar on the command prompt says:

C:\PROGRA~1\McAfee\MfeAV\MFEAvSvc.exe


There is no text within the command prompt that I can see.


I don’t recognize “PROGRA~1” and the capitalization for the exe file looks odd. This only happens when I open MS Office apps.


This only started happening a couple days ago, and first popped up when I opened an excel file that I downloaded for school. I ran a full scan using Microsoft Defender and an offline scan, but the problem still occurs.


I don’t know if this is relevant, but I did a factory reset of my laptop a couple weeks ago because I clicked a phishing link the month before and was worried there was a virus (but scans using McAfee found nothing). This problem with the command prompt wasn’t happening before the factory reset.
