Our computers at home have gotten the old "come on" for a virus fix. Please send off the debit card number. The alert flashes on your screen. I creates foreboding of possible loss of the hard drive within a millisecond. The debit card is whipped out in a nanosecond. Eradicating the offender can be done without opening up the checkbook. Sometimes it takes some time to do it. The virus will block your antivirus and other programs that protect the computer. One virus my daughter picked up proceeded to hide all her pictures and desktop icons. She was frantic. After some searching the cure was found. Computer set straight. The key is remaining calm. When a "virus" program you did not install pops up with warnings it is a red flags you might be had. Remain calm. Close down each program through task manager. Note the name of said virus scanner. Begin the search for the cure. You will not be the first that has picked up a damn nuisance.
