You're welcome, Harry. I've just added it to my Bookmarks in Firefox. I was using Maxthon when I bookmarked it yesterday. I read the bit about rootkits (typo: essenitaly should be essentially), they're scary, but not entirely new. I found a couple of things about them on the Symantec website. I Googled rootkits and found a couple of interesting things. This from Wikipedia and a free program from Sysinternals to find rootkits here. I don't know anything about this program, but you might want to check it out.

To err is human; to foul things up totally, you need a computer.
