Ok I've got a question, does avast 4.8 automaticly install 5.0 or do I have to comfrim it with the green box pop up?
Overriding 4.8 with 5.0 is NOT recommended. You should close out of 4.8 and stop the protection before installing Avast 5.0. Than go to Control Panel, and Add/Remove Programs to uinstall 4.8. After 4.8 has been removed, install 5.0. Upon two minutes or less after reboot, your Virus Definitions will auto update. Than open the program and get your new license key: (You need to be on-line to do this.)
1.) Go to Maintenance.
2.) Click on the Registration Button.
3.) Fill out the on-line form and submit it.
4.) You will than get your license key and will be protected for 12 months. After that time, just repeat the above process by going under the Maintenance tab and filling out the form again to renew.
