What does "quarantine" mean to a computer-virus? Well, I get a message that my laptop has spywhare on it. Suspecting I've a virus. I loaded up Norton and scanned. But after detection of a virus, Norton was unable to delete the file. Instead it allowed me to quarantine the virus. 1) Is "quarantine" the same as disabling a virus? 2) Is there a manual way to delete a virus?
