Sections Drop-down list and IE possible problem or server hacked ?

[Jacques]

Hello,

On my catalog pages http://www.distrimed.com/acatalog/index.html I've put a drop-down list with the top-level sections and sub-sections.
Yesterday I was on the phone with one customer (we were both using IE) my customer was looking for a given product and I said to him to select the corresponding sub-section in the drop-down list (at the same I was also selecting the corresponding sub-section in the drop-down list). The problem is, while I get to the right page of our catalog, our customer was redirected to another site (it was not a porn site or something like that, it was just a directory of internet sites existing in the "Cote d'azur". without any special link with us).

Have some of you encountered this kind of problem ?

I don't know if it's a javascript related error (so far I've found nothing) or if our server has been hacked (have you got some advices about checking a server integrity ?)

Best regards

Jacques

It's far more likely that the client's browser has been compromised than your server.

Many Thanks Norman,

That's what I thought but with Murphy's Law who knows ?
