Greetings ltlbit.
I guess Joe forgot to get you to move HijackThis to a permanent folder...this is pretty important because backups stored in temporary locations may easily get removed.
First create a folder, such as C:\
HJT.
Then move hijackthis.exe to this folder you created. Double-click hijackthis.exe click "Scan", and wait for the scan to finish.
Now please place a checkmark beside two more entries:
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http:// red.clientapps.yahoo. com/customize/ycomp/defaults/sb/*http://www.yahoo. com/search/ie.html
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http:// red.clientapps.yahoo.com/customize/ycomp/defaults/sp/*http:// www.yahoo.com
Close all other windows except HijackThis and press "Fix Checked". Then close HijackThis and restart the computer.
Is this a general check-up of your PC, or have you actually encountered a problem? And if it is the latter, is the problem still occuring now?
