I noticed (a couple of days ago) that everytime that I try to open IE it takes forever to open. When it does open and I'm cheking my yahoo mail if I have a message with a link and I click to open it it takes forever and it never opens. I'll appreciate any info' help that you can give me. Thank you.

As was said then,

Download HijackThis.
http://www.bleepingcomputer.com/files/hijackthis.php
http://209.133.47.12/~merijn/files/HijackThis.exe
http://www.downloads.subratam.org/hijackthis.zip

If you are on Windows XP, extract the file. Do not just doubleclick on it! This opens HijackThis in a temporary folder. This would interfere with the possibility to make back-ups.

Unzip to a folder other than your Desktop or the Temp folder. Then, doubleclick HijackThis.exe, and click "Scan".

When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that and copy and paste its contents in this thread.

Most of what it lists will be harmless or even essential, don't fix anything yet. Someone will be along to tell you what steps to take after you post the contents of the scan results.
