My computers been a bit odd lately, closing programs randomly and just generally being slow and useless – it was running fine up until a week ago. It started playing videos in the background for a few seconds at a time – which freaked me out because I didn't have anything open when I first heard it.
So I ran a scan with Malwarebytes, and the noises stopped. It found something and dealt with it (I guess – it restarted itself). When the computer woke back up it was ridiculously slow, and Norton was panicking in the right hand corner repeatedly telling me about “suspicious clouds” and "svc-something" (Sorry - it closes before I can read more than two words). Then it asked me to restart again so that it could install updates, but when it turned on again it told me that the updates didn't install properly. Nothing about the cloud though, but it still takes like, ten minutes from waking up to even be remotely useful.
Anyways it was too much weird in a short space of time - but nothing’s shown up in the scans since then. My computers still lethargic though, and has a bad habit of closing random programs if I leave them open when the computer hibernates.
Thanks for the help!
