Norton Anti-Virus won't work after System Restore
So my HP Pavilion/Windows 7 has been freezing during shut down the last 2 days and starting last night I was having problems launching certain software programs on my desktop. I assumed that I'd gotten some kind of virus and opened Norton up to do a full scan. However, like my other programs, it froze and after about 20 minutes and the screen read that it had only scanned 130 files. I made the mistake of then trying to do a system restore from that stage in normal mode, but since my computer froze during shut-down, the system restore didn't finish correctly. I think that's the point that Norton Antivirus turned itself off and now I can't get it back on. Everytime I open it, I get a little white window about 30px high by 100px wide. I'm given the option to turn it on in the taskbar, but clicking on the icon doesn't do anything. I re-open my computer in normal mode, tried to revert the system-restore point since it didn't go through correctly, but that one failed also - no doubt because the computer froze shutting down.
Since that stage, I have opened my computer in safe mode and done a system restore from even further back. That went through fine. I restarted my computer, ran a full scan with MalwareBytes (nothing), updated and ran a quick scan with Windows Defender (nothing), and then through Windows 7 Help forums determined that my internet connect was preventing my computer from shutting down. If I disable the internet connection, it shuts down fine now (or at least it has the last 2 times I tried it). My software seems to load okay, but I still can't get Norton back on.
