I think I have a virus: Norton isn't helping
So, I believe I have a virus of some type. I think it might be a trojan/keylogger, so I am typing this up on a separate computer.
I downloaded a game from this link (thepiratebay.se/torrent/7071588/Empire_Earth_2_Gold_Edition_[GOG]). I know it is TBP. I try games out, if I like them I buy them (being serious). It had reviews and many seeders, so it seemed fine. But that is not the point of this thread...
So anyway, I downloaded it, and it seemed fine. Passed the scan and whatnot. I open to try and install it, and a screen pops up saying "Checking File integrety". Right when the progress bar loaded, my computer got a blue screen. The error was long, and I believe it was a memory error. It said something about a required system file, although I don't know exactly what it said. My computer has a history with blue screens, so this is nothing new nessarily. I restarted a few times, it seems a bit slower, but still OK. later, I started getting random errors in other programs. I tried to run an install program, and got a memory error stating that an address was invalid. A few minutes later, I got an error in Norton Internet security, stating an unknown error happened (it was 4 numbers, might have been something like 3058). I thought maybe the program wasn't a virus, and instead was just a bad install program that caused a chain-like reaction and messed up my RAM. I tried to do a system restore to 1 month ago, but I got an error near the end of it, saying that it had failed with an unknown error, which was the same error the blue screen gave me. Very strange. The system restore did restore my registry and files, so I think it might have failed when it got to that bad system file.
I decided that this might indeed be a virus because it could be preventing a system restore, so I did a full system scan using Norton. 90% through the system scan, I got another error involving I/O in memory. My desktop only had the background picture, and all the other programs seemed to quit. I tried to start task manager, but when I did Ctrl+Alt+Del, it said it couldn't do it, and I should restart the computer. I did, and once again it just seemed a bit slower than normal.
I downloaded Norton's Power scan tool, but that didn't find anything either. I looked through all the processes and services, and didn't find anything strange (I keep note of what normally runs). I didn't see anything that suggested memory injection into something like windows explorer (I keep track of how much programs normally run in terms of RAM).
So I decided to look at the logs in Norton, and Low and Behold, I find the logs for the Firewall- Netowork/Connections filled since I started installing the game. Most of these logs just say "Protecing your connection to a newly detected network on adapter 'Teredo Tunneling Pseudo-Interface' (IP address: fe80::837:3fa8:9d23:49e4%22)." One of the logs says: "Connected to a shared network. (20 4E 7F 97 8D C8 is the Gateway Physical Address).
This has raised my suspision that it is indeed a virus.
Any help is welcome. I don't care what it is. Any questions are welcome.
TL;DR: Basically I have a virus that I don't know how to get rid of, and I need help.
