I recently attempted to torrent Nero software and I ran into a virus in the process. After finishing the download I ran the Nero setup and everything went as expected, this is until I tried to open the key generator. After I attemped to open the key generator I started to get hit with numerous pop-ups. I quickly realized I had turned off my McAfee firewall earlier and then re-enabled it. After doing so it brought up a warning that keygen.exe was trying to access the internet, I blocked all access as soon as I was able to. After this I restarted my computer and erased the folder that contained the file containing the virus. After erasing this folder I ran McAfee Virus Scan and came up clean, but the thing is I'm having problems with my computer. On startup I get a "45 runtime error." I also cannot right click on my desktop or folders in my documents. The only other strange thing I've noticed is I cannot run msconfig. Any suggestions would be greatly appreciated.
