Norton Internet Secutiry crazy. First asked for permission to defend Facebookagainst spam, and then he himself had spammed my wall in facebook that say he scanned my wall and I am protected. That is, software designed to protectme against spam - started spamming myself for my money.
Contacted the support service, said that want clean up NIS from my system and demanded my money back. Support said happily that he understands my anger and in compensation.... offered me an extra month subscription.
How many years did not know any problems with antivirus and you do not understand what to put instead of Norton.
