This is a warning because of the current IE bug, I had that in mind for soem time but forgot to inform you guys, sorry. SENuke uses IE, I don't know about other popular tools but I am sure many use IE as backend. Using such a tool on the wrong page will get you infected with a trojan. I mainly think about wordpress sites and similar ones. The IE bug triggers when you enter a website that is infected and alone in UK I heard > 10,000 infected sites are currently known. If you work with a tool that's using IE as browser you can try run it through sandboxie Code: http://www.sandboxie.com/SandboxieInstall.exe That's a free tool that mainly seperates your real harddrive from the programs used through it. It can not stop a trojan/virus but it will be installed in the "sandbox" and not in your real windows root.
