Avasts self protection needs to be disabled before attempting a restore and if you search around the forum you’ll see this mentioned many times, this is also another reason to use system images rather than restore points as there much more reliable for many reasons other than just this problem.
You’ll need to use the removal tool http://www.avast.com/uninstall-utility in safe mode to remove remnants of avast after first uninstalling normally, once the tool has been run you can reboot back to normal mode and install a fresh copy of the avast version you require and insert your license.
NOTE that you might want to remove your email information from the screen shot you took unless you want an attack of the spammers
