Symantec has been bending over backwards to reassure AOL users
after the Intrusion Detection signature that was loaded with the latest update prevented people from logging into the ISP. As a result of the problem, which affected both Norton Antivirus and Norton Internet Security and Norton Personal Firewall, traffic coming from AOL was deemed to be malicious and was blocked. Ultimately, the bug was traced to the area that prevents hackers from entering a computer through open ports.
Symantec says it fixed the bug within seven hours but was forced to publish a fix for people who continued to have trouble. If anyone cannot get onto the Internet because AOL is their ISP, Symantec recommends disabling the security software to fetch the patch.
