Hi everyone at proxy2.de,
I have your guestbook application in my site and have had the same type of multiple url links dumped into it at times as well.
The similarity with the type of multiple url's being added by someone to your site prompted me to send this.
I'm sure you may have extensive AV security in place but these groups of links can catch you out when going to check them. So beware.
This is what I got loaded into one of my machines:
Downloader.Tiny.fl
Hijacker.Agent.hz
Logger.BZub.hg
Backdoor.Ncx.a
Worm.Warezov.jq
So others are aware re: be careful because some of these multiple links maybe are - malicious and redirectors.
Thanks for the guestbook application which I have found useful and challenging having on my website.
