I recently was the lucky recipient of the old "klez" worm. It came to me through a friend who had just downloaded Kazaa. Took us three whole days to get rid of it. The keywords in that virus are "I hope you would enjoy it" or variations of that.
Use
AVG Anti-Virus. You'll never have another virus again. I found and got rid of my klez worms using AVG. (Sounds like a weird commercial, doesn't it?)
AVG just added the Fizzer virus to its database today. So, thanks for alerting me to the virus. I'll update today.
AVG has a free version, which is what I use. I think the only difference between the paying & the free version is, with the free version you have to remember to go to the website & download the updates yourself, whereas with the paying version, it does it automatically. (I could be wrong.)
I just got the Klez Virus in an email attachment. Norton "quaranteened" it, said it couldn't eradicate it. [Didn't use that word, exactly]
