Up until this morning, I utilized AVG free virus protection. Now I'm back with Norton. Here's the story. Last week I detected that I had contracted the Ransom Virus upon two occasions. Likewise, the AVG isolated the problems. To further, this morning I got a phone call from a Arnold Katz at 718-763-0616. He said that he was aware of my computer having a problem, and if I would turn on my computer (and it was off), he would explain how to fix it. I responded by telling him that I was not interested and hung up the phone. I don't know if this issue would qualify as an 'Alert', but it sure spooked me.
