i just formatted my machine and installed all the drivers. I then downloaded anti-virus software(panda). However there is this symbol on the taskbar that looks like the "help" symbol for windows. blue sircel with white boundaries and a white question mark inside. It flashes to a red circel with a diagonal red line, like in "stop" or so. And it constantly keeps popping up a message about antivirus programs and what I should buy and so on.... it all ends in alot of adds on the internet. could someone please help me get rid of it? ive scanned my pc with panda but it doesnt find anything.....
