I think you should check your System for Infection.
To determine if the malicious code is on your computer, search for the following files:
kk32.dll
surf.dat
Steps for users of Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003:
On the taskbar at the bottom of your screen, click Start, and then click Run.
In the Run box, type: cmd and then click OK.
At the command prompt, type:
dir /a /s /b &systemdrive%\kk32.dll
and then press the ENTER key to search your computer.
If the file is present, the file path is displayed. If the file is not present, a message is displayed that the system cannot find the path.
At the command prompt, type:
dir /a /s /b &systemdrive%\surf.dat
and then press the ENTER key to search your computer.
If the file is present, the file path is displayed. If the file is not present, a message is displayed that the system cannot find the path.
If either of these files is present, your computer may be infected. You can find tools to clean your computer and obtain up-to-date online antivirus protection from McAfee or SecureSynergy.
