That was a silly thing to do!! Seriously though, NOD32 is one of the best virus killers on the market, however it sounds as though the viruses have disabled access to certain update servers such as the servers NOD32 would use to update, these modern viruses are getting really nasty.......
Here is what I suggest you try: Download & run combofix from here
http://www.combofix.org/ MAKE SURE YOU FOLLOW THE INSTRUCTIONS, or you will break your OS

When combo fix has finished download & run Malwarebytes Antimalware free edition from here:
http://www.combofix.org/malwarebytes.php This whole process may take some time, but between them they should clean your system up nicely, polish off with a NOD32 scan as well just to make sure & make certain you delete those old system restore points or you'll be back to square one!
