I was browsing a news website and the computer froze after I clicked on a link. I waited about ten minutes, still "processing" and decided to restart. After restarting, I got the same problem within a couple of minutes of restarting, this time while trying to open a PDF file. This happened several times, but when I restarted in safe mode with networking, everything works great.
I ran Malwarebytes anti-malware and it found a few things, but restarting in normal mode I got the same problem again. I ran Malwarebytes again in safe mode, and even more stuff was found, but again, restarting in normal mode the freezing issue reoccurred. I have tried a bunch of anti-Virus scans from safe mode, since running Symantec in normal mode does not work (it starts, but then a few minutes later when the freezing happens, the scan cannot continue) with a few different companies, but either nothing is found, or a few things are found, deleted, and then restarting in normal mode does not show any improvement.
I am convinced there is a virus lurking but I can't seem to clear it out. What should I do?
