i keep getting a 503 message on sites that work on my other computer. things try to download all the time i just keep canceling them out. i have AVG and Advanced System Care. i ran those and they found nothing. i just downloaded Malwarebytes and that did not fix the problem either. also when ever i start the computer a pop up says "Persistence Module Not Working" i don't know what to do now. if someone could please help me i would really appreciate it.
