Hi Georgia,
Please move HijackThis to its own permanent folder as shown in any of the 'good' examples below --
C:\ Documents and Settings \me\Local Settings\Temp\HijackThis.exe <-- Bad, HJT in Temp folder
C:\HIJACKTHIS.EXE <-- Bad, HJT running directly from hard drive
C:\Documents and Settings\User\Desktop\HijackThis.exe <-- Bad, HJT running directly from desktop
C:\Documents and Settings\me\My Documents\HijackThis.exe <-- Bad, HJT not in its own folder
C:\Documents and Settings\User\Desktop\HJT\HijackThis.exe <-- Good, HJT in its own permanent folder
C:\Program Files\hijackthis\HijackThis.exe <-- Good, HJT in its own permanent folder
E:\Utilities\HijackThis\HijackThis.exe <-- Good, HJT in its own permanent folder
C:\HJT\HIJACKTHIS.EXE <-- Good, HJT in its own permanent folder
Download Ewido Security Suite from here:
http://fileforum.betanews.com/detail/ewido_security_suite/1098736486/1
Install and update it, and then close the program (don't scan yet).
Reboot into Safe Mode and run a full system scan with Ewido allowing it to fix whatever it finds... save the log from the scan results.
Reboot normally, close any open browser windows, scan with HijackThis, and post a new log along with the Ewido log.
