I've been noticing some strange behavior on my PC lately. When I leave it alone, it randomly locks the Windows OS, or it opens web pages like Twitter and Reddit without me clicking anything. I've already done a virus scan with MalwareBytes and Windows Defender, but they didn't find anything suspicious. I really don't want to be paranoid, so how can I ensure my computer isn't being accessed by someone else?

First off, check your Task Manager, Task Scheduler, and Event Viewer to see if anything unusual is happening. You should also look into app permissions and see if there are any unknown users logged in. If nothing pops up, consider doing a deep or offline scan with your antivirus. Remember, if you find any weird names during this process, Google them to avoid jumping to conclusions!
I did everything except the deep scan, which I’m running now. In the Event Viewer, I saw some warnings linked to 'hznucmon,' but couldn't find much info on it. Any idea what that is?
