I have a Panasonic toughbook. I had NOD32 antivirus checker on it. One day when I was connected to the internet, I got the message "Virus xxx detected. Do you want to Delete or Quarantine it?" I said delete and NOD32 said it had been done. But the virus was still there. I disconnected from the internet and removed the virus from my windows registry after getting into the Safe mode. The moment I connected to the internet the virus was back. If I load Norton or something else, the antivirus checker goes to the internet to get the latest update and automatically gets infected. Is there any way of getting rid of a virus without having to reinstall XP?
