Hi and welcome to Daniweb forums :).
Can you please do the following.
===============
I'd recommend that you install all the critical windows updates available from Microsoft, up to service pack 1. This will help to make your system more secure and prevent many 'problems' from reoccurring in the future.
===============
Scan with HiJackThis, then check(tick) the following, if present:
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://red.clientapps.yahoo.com/cust...search/ie.html
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://red.clientapps.yahoo.com/cust.../www.yahoo.com
R1 - HKLM\Software\Microsoft\Internet Explorer\Main,Search Bar = http://red.clientapps.yahoo.com/cust...search/ie.html
R1 - HKCU\Software\Microsoft\Internet Explorer\SearchURL,(Default) = http://red.clientapps.yahoo.com/cust.../www.yahoo.com
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Local Page =
O3 - Toolbar: ZeroBar - {F0F8ECBE-D460-4B34-B007-56A92E8F84A7} - (no file)
O16 - DPF: {56336BCB-3D8A-11D6-A00B-0050DA18DE71} (RdxIE Class) - http://software-dl.real.com/0330d833...p/RdxIE601.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.

If you have an "always on" connection to the internet, physically disconnect that connection until you are finished with Safe Mode and have rebooted back into normal mode.Next, please reboot your computer in Safe Mode by doing the following:
Restart your computer
After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
Instead of Windows loading as normal, a menu should appear use arrow up to highlight
Select the first option, to run Windows in Safe Mode hit enter.
For additional help in booting into Safe Mode, see the following site: HERE
