Good Afternoon, I apologize that i dont know very much about computers so I may not be the best at describing my issues. I use an HP Pavillion dv6700 with Windows Vista. Last night I was at the movies 25 website where I have streamed a movie before. I was sitting on the district 9 page for a couple of minutes and all of the sudden I started getting messages from Security Center saying I was being attacked by a virus and telling me to install block scanner to get rid of the viruses. A window also popped up that looked like the "my computer" window and under the C drive it said I had 8 viruses, 1 in the D drive and 9 in the E drive, which of course doesnt make sense. I was repeated prompted to run the block scanner program and asked if I would allow the program to run. I have Norton Antivirus so I ran a full scan, and when I woke up this morning it had come back with nothing but a tracking cookie. I am still receiving a popup window telling me im being attacked by a trojan blocker, except with a spelling mistake 'Troyan' and asking me if I want Block scanner to remove the virus. I click no but it just keeps coming back every 5 minutes or so. If i click yes it takes me to a website where i can buy block scanner. Last night I noticed that when the security center icon popped up at the bottom (red shield with white X) if i clicked on it i couldnt actually go to any of the things outlined in the window. for example "help for using Windows Security Center" would just send me to the block scanner webpage. Also the window that comes up from clicking the red icon is different than the security center window that comes up when i open it from my start menu. What is going on?
