Comment I got lucky, but it's a disaster! (Score 2) 36
This problem affected my company, fortunately, I don't have too many staff (about 20). Apparently somehow defender is detecting both Start Menu links and Quick Links as a virus and disabling or deleting them. The quick fix to stop it from spreading is to shutdown the "Block Win32 API calls from office maco" features in endpoint protection. It doesn't fix any links that it screwed up thou. Considering most staff don't know how to go directly to executable to launch it, I feel bad for anyone who's in the thousands of staff. It knocked out Chrome, Edge, Outlook and the entire Office Suite... Well good luck to anyone dealing with this!
