Config: Gateway laptop, windows 7 home premium 64 bit. AVG2012, I think.
After downloading an update, the update asked to reboot to complete the installation. After doing so it won't reboot. Tried avg rescue disk, it won't boot. Took the hard drive out, hooked it up to another computer, and renamed avg* drivers per previous forum postings. Still won't boot.
Could be coincidental and some other problem, but hard to believe.
