After previously struggling with the PUM.bad.proxy virus I've become very paranoid. After updating Java on both my computers, I noticed the port box in lan settings being filled with the number 80. The address box is empty and I am not being forced to use any proxy. I've researched a bit and port 80 looks safe but I didn't have it in the LAN setting window prior to updating Java. So my question is, is port 80 suddenly appearing on the LAN settings safe or is this a virus?

Thank you.

http uses port 80. You're going to be fine with this enabled. Protect yourself locally and anything that comes through port 80 is going to be stopped.

 

Firewall

Anti-virus

Regular scans 

Router Security setup

etc.

BTW, using Java is an unnecessary security risk...especially using older versions which have vulnerabilities that malicious sites can use to exploit and infect your system.Although, Java is commonly used in business environments and many VPN providers still use it, the average user does not need to install Java software.I recommend just uninstalling Java if you don't use it.

If you're going to use Java, many security researchers and computer security organizations caution users to limit their usage and to disable Java Plug-ins or add-ons in your browsers.

If you need Java for a specific Web site, consider adopting a two-browser approach. If you normally browse the Web with Firefox, for example, consider disabling the Java plugin in Firefox, and then using an alternative browser (Chrome, IE9, Safari, etc.) with Java enabled to browse only the site(s) that require(s) it.

To defend against this and future Java vulnerabilities, consider disabling Java in web browsers until adequate updates are available. As with any software, unnecessary features should be disabled or removed as appropriate for your environment.
