Whats going on here??

Viruses and worms

I have a new hp dv7 with the i7 processor and 8 gigs of ram that has been acting up. I ran a boot time scan and everything came back clean except for a false positive. when using my computer the program in use will freeze up and become unresponsive. When I press ctrl+alt+del the windows screen comes up but when i select task manager nothing happens. It just goes right back to my desktop. So i restart the computer and try to access the task manager and everything works fine. This has happened at least 5 times today…any guesses as to what might be going on here?

ran a quick scan with malwarebytes and found backdoor.bifrose could this be the culprit?

could you post the Malwarebytes log ?

I have a new hp dv7.......
you did remove any preinstalled AV before installing avast ?.....hp usually come with a 60/90 day Norton Since running multiple AV can create all kind of windows errors and False Positive detections... it is also recomended to run a removal tool so any leftovers are gone
