avast pro stopped working

My notebook is Pavilion dv6, with windows 7 home premiun.
Last night, I did an analysis from the start, and during the check informing me about the presence of foreign elements and asks whether to delete, send to the trunk (option 4), etc… Select option 4, but no reply. He hung up the system and this morning, windows 7 suggested that the system recovery happen. I open all windows either, only antivirus does not work. Get the message insecure. Join the option to fix now, but it works.
As I can solve?

did you try avast repair and reboot?

For a repair of avast. Windows, Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button from the pop-up window, scroll down to Repair, click next and follow.

was you computer delivered with a preinstalled AV ? HP often come with a 60/90 day Norton have you used any other AV before installing avast ? did you uninstall it before installing avast ?

it is recomended to run a removal tool so any leftover files are gone

run and reboot - Uninstallers – Security Software

I have the same problem, same computer, same OS, win7 premium!
my avast 6.01367 stopped working, cant turn it on, nor off… tryed to restore
my comp to an earlier time, but it said that antivirus program is turned on and
restore cant be done. But i still recieving a message that my avast is turned off,
