Well according to your image you have the latest version of avast and VPS, so I to would suggest checking the system date.
If the system date is correct, I would also you check the about avast and ensure it is the same as that of the image you gave.
If all seems fine, it wouldn't hurt to try a repair of avast. Add Remove programs, select 'avast! Anti-Virus,' click the Change/Remove button and scroll down to Repair, click next and follow. You need to be on-line to do this.
