Skype steals port 80!

I spent about an hour this morning trying to fix someone's PC that was behaving very much like it had malware, running really slow and their local copy of Apache wouldn't run..

Turns out that it was Skype port-hogging, stealing port 80. Killed the process and took Skype out of startup so it only gets run when it needs to be - problem solved.

Apparently it does this to "get around firewall issues" - presumable with the whole grid-networking nature of Skype it needs to be able to get access to a node, and port 80 is the easiest way to do it.

Anyway, rant over.   Just thought I'd mention it as a heads-up so that hopefully people don't waste time like I did.
