Your best bet would be to post a HijackThis Log in the HJT forum and wait for someone to reply to you. Seems that you have a virus infection.
To get the log:
Please download the self-extracting version of HijackThis from here:HijackThis Installer Download
to your desktop.
Double-click the file then click the Install
The file will be extracted to C:\Program Files\Trend Micro\HijackThis\HijackThis.exe
A shortcut for future use will also be created on your desktop and the Intro Frame of HijackThis will open.
Click Do a system scan and save a log file
Then, post the log in the HJT forum. Please wait patiently for someone to get to your log, since the members of the HJT team have many logs waiting for a reply before yours.
