Still stuck and not enjoying ICQ, then go to Step 3.
Temporarily disable your antivirus or firewall running in the background. Now if you can access ICQ, be aware that your security software is causing problems. Try adding ICQ in the set of trusted sites.
DNS is a service that translates ICQ into a machine-readable address called an IP address. In most cases, this work is done by your ISP. If only specific sites are not opening, it is likely to get corrupted.
