trojan? how?

[dapslyrics]

Ok I do not know how this is happening. I'm getting emails saying that my site is dishing out "JS/Nezew" trojan on every page of my site. I went to [vil.mcafeesecurity.com...] it says "This threat is detected as JS/Nezew. This short, encrypted JavaScript trojan does not function due to a bug in its code. May arrive via E-mail Spam messages." I've contacted my webhost and they say there's nothing wrong with my box. Contacted my webdeveloper and he says it could be my pop up ads. I don't run any gator, or any installer pop ups so I don't know how that's possible. Adtegrity of course says the ads do not have viruses on them. I've tried going to my website with my firewall & pop up blockers turned off and I didn't catch anything. I don't know.. it's driving me nuts though. I get about 5 emails a week saying that they got that trojan from my site. Can anyone answer this?

check all your asp, html, htm and js files. I remember reading an article that said hackers were breaking into some websites and appending malicious code into existing web pages. this could be your problem.

Thought I would share a possiblility with you.

It may very well be that the "virus" is NOT being generated by you directly in any way what-so-ever.

It may be caused by someone else "hotlinking" your page.

This is also common with today's email viruses. They can be generated on someone else's infected computer if that person has your contact information.

The virus would not only replicate itself using the infected computers email address, but also that of everyone else listed in the address book, giving the appearance that it came directly from you.
