Internet browser is to slow loading, and myfreeze takes over search

I ran ccleaner, and antivirus, and Malwarebytes' Anti-Malware, nothing showed up. i uninstalled RegCure and Myfreeze.com from program list. My wife said the screen was black today she rebooted 2 times, and Windows Vista started to rework it self back. This is a HP6337,500GB hard drive. The Explorer 8 browser, is it really any good?
