- Cannot connect to the Internet
- Disabling of firewall during virus attack
- Web pages do not load completely
Cannot connect to the Internet
After upgrading to Windows XP Service Pack 3 on your computer you might not be able to connect to the Internet. In order to resolve this issue you need to turn off the firewall and then test your Internet connection again. In case if you are able to connect run the connectivity troubleshooter of your antivirus product and then turn on the firewall again. If you are again not able to connect to Internet you need to download latest virus definitions on a computer that can connect to the Internet. Now, update the virus definitions on the computer that cannot connect to the Internet. Run a full system scan and try connecting to the Internet. If the Internet connection still does not work reinstall your antivirus and firewall programs and connect to the Internet.

Hence, to avoid this issue you need to run an antivirus scan on your system and turn on the firewall.
