Can't access several sites

Hi,
new member here

My problem is that I can't access some websites on the net that I've been able to before today. I can see some websites like this forum and google fine, but some others it just says navigation was canceled or can't find this page, etc etc. I really don't know if it's being caused by a spyware/malware of some sort. I've scanned my pc with Spybot, AVG, SuperAntiSpyware and treated the items they found, but the problem is still there. I hope there's someone who can help me out, ty.
