Okay so I didn't bother with this issue because whatever it is that's messing up my laptop never caused a huge amount of problems for me. However I do realize something is wrong with it, and I'm suspecting a virus. I think this has been going on for maybe a year, I just thought it was hardware related. But looking at window's update I realize my laptop hasn't updated since 7/31/2015 and that last attempt failed.
Here's what's generally going on:
-CPU will spike to 100% usage randomly and remain that way. This happens no matter what programs I'm running. Looking at the resource monitor, svchost will randomly start using up to 50% of my cpu. Far as I understand it shouldn't do that.
-Windows update will search for updates forever but it won't find any. It should be updating though
-Microsoft security essentials will not update. I had to manually install a new version a few months ago
-Games which used to run fine on my computer will now freeze up entirely not too long after I start them, despite there being little to no lag in game
-Antivirus/antimalware programs can be installed for some reason
-I vaguely remember being redirected to websites I have never seen before upon opening my browser a couple times. This doesn't happen often
-Other resource-heavy programs such as photoshop and firefox will freeze up for several minutes and crash occasionally. Again, this wasn't happening a year ago.
Here's what I've tried so far:
-Multiple attempts to scan using microsoft security essentials in safe mode with networking disabled
-Scan using emsisoft antivirus today because i couldn't update my regular antivirus. It turned up with some results for some type of ad/app installer. it was listed as no risk
-Scan using malwarebytes - nothing turned up
-Scan using spybot search and destroy - nothing important turned up
-Attempt to update windows again - all it said for multiple hours is searching for updates
-Attempt to address issues with my games and programs - all that lead me back to is that there aren't enough resources for them and that's why they freeze
The last three scans were done outside of safe mode because I'm working on something
Yes I know I should've addressed this earlier but my laptop was not important to me last year. Now I do lots of art with it and play games on it often so I'd rather not lose all my data :( any help would be appreciated
