While we are on the subject of personal computer security software, from time to time a malicious program may succeed in corrupting your security software. One of the results of this corruption is blocking of ports by Norton Internet Security. It appears that when Norton Internet Security is corrupted it goes into a “emergency mode” and blocks several ports.


Every so often a malicious program/virus/etc will damage the Internet Security installation. When this occurs, sometimes the internet security software such as Norton Internet Security will block ports( in this case it is port 110).

The solution to this problem is to uninstall and reinstall your Internet Security software.
