Chances are someone has hacked in, they will not have used your computer to do it though so you should be safe enough.
No, nobody has access to my computer but me, so it should be safe.
CHECK YOUR COMPUTER FOR NASTIES. Its unlikely but they may have managed to install a keylogger on or similar software and grabbed your login details.
I run Windows Firewall, AVG, Spy Sweeper, Spyware Doctor, and Spybot (all at the same time), so hopefully they keep the nasties away between them. I will scan though.
Also think if you have allowed access to anyone else. Occasionally friends do stupid things like post your stuff on the internet.
No one has ever been given the passwords for the control panel or the FTP access. One person has access to a subdirectory, but she cant access anything but that, and only knows how to put pics in it.
my guess is the chat thing you installed wasnt kept upto date and someone found a flaw in the php
allowed them to write their own code to the site
That may be - I never went back to it after we decided it was rubbish. What I cant figure out is how a hacker even found my site, I have the robots.txt set to no robots, so it shouldnt be listed anywhere.
happens with large scale stuff like blogging sites and bulletin boards quite a bit
That must be why Invision keeps releasing new patches for their IPB boards, I guess. I dont remember seeing any for the PHPBB boards though.
Thanks very much for your help and advice, both of you. I will now go and scan my computer...
