I am amazed at the help you provide people in this forum. So, now that I'm in a bad situation--troubled by a Trojan--I, too, would appreciate your help.

I've run Ad Aware and Spybot--both show a clean slate but previously showed that I was infected with EZula, Xren.A and Troj Qdown.l. I've gone as far as I can without some more intelligent guidance.

I appreciate your time and attention!

Here is my Hijack This log:

You need to get the latest version of HJT, please follow all of Owen's instructions HERE and post a fresh log.

Thanks for your earlier response. I 'believe' that I have followed all of Owen's directions. Here is another log using the latest version of Hijack This.

Again, I appreciate your help.

Click Fix Checked

Nothing else troubling in the log. Could you possibly tell me where AVG is detecting these trojans?

Thanks for your help Owen--and happy birthday.

Regarding your question about AVG--it detected one of the infections a few days ago but was unable to delete the file. Since then, I've used so many programs to try and restore order to my system--that I'm not sure what is what. ( :

Cheers!

If AVG pops up with a message again, then get back to us. You could perform a full scan and see what AVG reports.

By the way, you have two antivirus programs. You only need one. If you are going to keep AVG, make sure you get the latest version which is AVG 7 from http://free.grisoft.com
