Safe Zone will not open

Laptop HP notebook. Chrome. Avast does not show up on my control panel, it’s an app. I am connected via wifi. I have avast pro and safe zone. I opened safe zone the other day to do some banking and everything was fine. I tried to open it today and all I get is the first orange and white screen but no browser window.

I went back to setting and reset to default. I have also done a quick scan. Some files were marked that they could not be scanned because of a missing password. I looked at them and they were all related to Flash X. I had tried at some point to installed flash X when avast was open and it never worked. So I left it alone.

I have turned my computer off about 5 times now. Still the browser will not open. Any suggestions?

I’m not at all computer savvy.

How do I handle files that avast! can’t scan? http://blog.avast.com/2014/02/28/how-do-i-handle-files-that-avast-cant-scan/

did you just install avast?
did you remove your previous used or factory installed AV according to vendors instructions / removal tools?

General: Uninstalling a third-party antivirus software. http://www.avast.com/faq.php?article=AVKB11
