look up a program that is called stinger and run it from either a cd you burned of it or off of a usb stick.it's a freeware and has been used by several of my coworkers on their own personal machine and they say it is very good.don't count avg out just yet either.avg is an amazing security program and i use it on ALL of my machines,both work and personal.you also need to look at running superanti-spyware and malware anti-malwarebytes from a usb stick as well.gl with it all and let me know if you have any other concerns or questions.
