I have Norton Internet Security 2007, and when I look in the History section, I can see a few "medium risk" intrusion attempts coming from the same computer (named as Daniel) with the same IP address. Norton calls them "HTTP Apache Redundant Slashes DoS". Daniel Whelan
This is a denial of service (DoS) attack on very old versions of the Apache web server, and works by repeatedly requesting addresses that contain ////////////// to overload the server. You're not running Apache 1.24 or older so it won't affect your PC. However, you could search a Whois service such as DNS Stuff (http://www.dnsstuff.com/ and scroll down) for the IP address, find out who registered it, and report it to the abuse mailbox.
Backchat: Unlike me, Karl Wilcox, a lecturer in computer science, noticed that the attacking computer was also called Daniel. He deduces that Daniel "has loaded a page containing a link (probably an image link) which contains lots of slashes, something like .../images//////picture.gif. You get these sometimes from generated page links or sloppy editing. Daniel's PC loads the original page, then tries to load the image which Norton Internet Security interprets as an attack. Same thing happened to me!"
Many thanks, Karl!
