Got it that time.
Reinstall AVG, just right over the version that is installed now. Then go to the event viewer logs just as you did before, but this time instead of saving the log, select clear the log. You will be asked if you want to save them first, that is your choice. Once you have done both, reboot the computer. Once the computer has started up fully, see if the AVG gui is working. Let me know. Also give me a new set of event viewer logs. This time they will be small enough to attach here.
