Hi. I was on the internet the other day and i was trying to watch a video on a website and it told me I had to download Active X. I did and then my computer went crazy. Two programs downloaded themselves onto my computer. They are security troubleshoot and online security guide. I cannot access the internet at all on my laptop. I have run scans on Norton twice and half way through them a blue screen pops up say window has had to shut down to prevent damage to my pc. I have two icons on my toolbar. One of them is a shield the turns blue and red and the other is a yellow triangle. If anybody can help I would greatly appreciate it.
