Hi and welcome to the Daniweb forums :).

Can you please do the following.
===============
You will have to disable Spybot's Teatimer before we begin, as it will interfere with the fix. To do this can you start Spybot and go to the Mode button and select Advanced. Go to Tools > Resident and uncheck the box next to Tea-Timer. Make sure that the icon in the system tray is no longer there. If it is, just right click on it and select "Exit".
Download ResetTeaTimer.bat.
Double click ResetTeaTimer.bat to remove all entries set by TeaTimer.
Do not forget to re-enable teatimer when we are done :).
If teatimer gives you a warning afterwards that some changes were made, allow this instead of blocking it.
===============
Download the newest version of HiJackThis ; version 2.0.2. Place it in a permanent folder before scanning. Repost your log after following the steps below. This version has features that might be more helpful in 'cleaning' up your system.
===============
Scan with HijackThis and then place a check next to all the following, if present:
R3 - URLSearchHook: Yahoo! Toolbar - {EF99BD32-C1FB-11D2-892F-0090271D4F88} - (no file)
O4 - Global Startup: Adobe Acrobat Speed Launcher.lnk = ?
O11 - Options group: [INTERNATIONAL] International*
O16 - DPF: {9522B3FB-7A2B-4646-8AF6-36E7F593073C} - http://a19.g.akamai.net/7/19/7125/40...02/Coupons.cab
Now, close all instances of Internet Explorer and any other windows you have open except HiJackThis, click "Fix checked".
===============
To help protect your system from hostile ActiveX content, or special 'downloadable' files:
Download, install and keep updated, SpywareBlaster . If you've installed it for the first time:
1) Check for any available updates; if present, they'll be automatically downloaded and installed.
2) Next, "Enable all protection".
3) Exit the program.
-
Note: Remember to regularly check for updates.
===============
Download the HostsXpert.
Run it and press "Restore Original Hosts" and press "OK". Exit Program.
Note that if you have a custom host file, this will remove it. You can edit the host file with this program too.
===============
After rebooting, rescan with hijackthis and post back a new log. Please let me know how your pc is now.
