Hello leann and welcome to Seven Forums. Sorry to hear you're having these issues.
If you can access the internet through safe mode with networking, you might be able to install the free version of Malwarebytes. It has a good reputation for finding and removing the bad stuff. If you click on "Products" you'll see the official link for the free version.

Microsoft also has a free product called Windows Defender Offline (formerly called Microsoft Standalone System Sweeper.) If you have access to another computer (and if your netbook meets the minimum system requirements as contained in the "Note" box) you can create a bootable CD, flash drive, etc to scan your infected machine.

A very strong caution about registry cleaners. They can seriously damage a computer. Sometimes worse than malware. So use any registry cleaner with extreme care.
