I have been getting a lot of spam from this company telling me that they have my account (which I don't have after searching my computer) on hold and needs to be renewed by paying them money now if I want to continue using their software. This has been going on for over a year so I wrote them a letter about the extortion style of advertising. The weird part is when my real security software is due to be renewed, this company sends me renewal e-mails which look very much like it's from the real company I use. I told them to provide proof that I bought their software and have been using it. They wanted me to go to a paypal account or the account they say I have, but I have not given them money or installed their software. I told them to do their own work and send me the PROOF. They wanted me to provide the numbered account which would be impossible since I don't have one. So far, nothing. Beware.
