Our computer has crashed 5 times in the last 2 1/2 weeks, and each time the Stop error was the same error 0x0000004A. I would appreciate your help in fixing this problem - I am a 75 year-old woman with only average computer knowledge. Thanks!

Welcome.

It appears the existing BitDefender antivirus is the problem. Uninstall it completely, then install free Microsoft Security Essentials from the link below:
