Last night a hand full of my Microsoft apps started acting very odd. Out of, seemingly, no where my Skype stopped working and would simply switch, rapidly, between 3 different conversations over and over and over. My emails were unusable and just went straight through them to the Archive tab then just sat there. There was a strange flickering on the page tabs for Windows Defender Security Center but this was ultimately useable. The Windows app store just went into a melt down if I tried to get in. It would just start refreshing like crazy, every second.
I did all my scans with defender and Malwarebytes which returned 0 results.
I had just installed a new driver update so I rolled that back. Nothing.
In the end I bit the bullet and decided to just do a full restore (I'd been considering doing one anyway so this was by no means the end of the world) and reinstalling Windows. But when I did this and got back in it was still doing it! Only now I had to use Windows Edge and this was totally unusable, again in a constant state of refresh. So I shut it all off for the rest of the evening.
I had another look about an hour later and it was all fine, back to normal as if nothing had happened.
My housemates think I was hacked but I'm skeptical of this. I'm more inclined to believe in was something going spoony with software or something (I dunno, I'm by no means an expert!). I was just wondering if there's anything I can do to see if there is anything suspicious going on with my machine now? As I said, I did the usual scans and they returned nothing.
Hoping to hear from one of you lovely lot soon!
