1. Go to GeeksToGo and look for the Remove Malware/HiJackThis forum. Click on the "Please Start Here" link.
2. Read the instructions carefully. They will tell you what to do. The instructions will include running HiJackThis and posting a log to the forum.
3. Someone on the staff at GeeksToGo will respond with an analysis of your HiJackThis log and will give you further instructions and a request to post a new HiJackThis log.
If your problem is simple you may solve it in one or two HiJackThis analysis cycles. In my daughter's case, which was severe, it took about 8 cycles and two days. But it worked. The guys/gals at GeeksToGo are very good. They will point you to various free utilities that have been developed by them and others that are specific to your problem. They are very knowledgeable when it comes to adware and malware.
It is a good site. the "cures" work if you read and follow the instructions carefully.
Much appreciate your info and post. Filing it in hardcopy as well.
God's best to you and yours.
