Have you tried opening those sites with another browser? If not, try that once. If it works, it's your browser that's the problem.

Are you having problems opening any other sites or is it just the AV sites?

Try to scan computer by using antivirus/anti-spyware with latest signature, afraid it's caused by virus/malware.

If it's not virus/malware problem, ensure there is no problem on DNS server, you should be able to use nslookup to resolve domain name without problem if DNS servers work well.

Hope this helps.

Ok, this sounds like it may be a DNS issue. Which is to say, your computer may have the wrong DNS address.

How does your PC connect to the internet? Is it directly connected to the modem or is there a SOHO router in between?

Are there any other computers in your network that don't have a problem that you can use to compare TCP/IP settings with the problem computer?

Open a command prompt window (Start >> Run >> type cmd and hit Enter) and type the following command:

ipconfig /all

Post the results in a reply in here. Since you're connected directly to your modem, just post the first two octets of your IP and use x's for the rest (ex: It's always best not to post your complete external IP address. There's no point in asking for trouble right.

Just an FYI, you might want to consider buying a SOHO router. They're relatively inexpensive (around $40 - $50 US) and will provide a firewall, NAT and DHCP so you can connect multiple computers safely (the firewall right) to the internet.
