Can't open google chrome; pc very slow; firewall malfunctioning messages

Hello there,
I'm glad I found you guys!
Our pc is been acting out for the last couple of days: slow internet surfing, couldn't get msn signing page; but today got message firewall is malfunctioning and can't open Google Chrome anymore.
I attached the logfiles from the Farbar Recovery Scan Tool as advised.
Please help!
Thank you
