In order for us to help you it is necessary that you provide us with a HijackThis log. The HijackThis log is merely a text file, so you should be able to copy it onto a disk and move it to another computer that is able to access this site. Do not use a USB flash drive to transfer the text file, use a floppy, a CD, or even a DVD. A USB flash drive may become infected if plugged into the infected computer... then it could transfer the infection to the clean computer. Next, just copy and paste the contents of the log into a fresh topic, as this one will be closed.
A HijackThis log, as well as other logs that may be requested, provide us with a guideline for removing whatever malware is infecting your system. We cannot proceed without such logs for guidance.
Please follow the guideline at the link below to start a new topic and post your HijackThis log. If you are unable to create and post a HijackThis log, then your only option may be to reformat your computer and reinstall the operating system. This topic is now closed.
