After I update the latest AFA(Avast Free Antivirus), IE11(Internet Explorer 11) doesn’t work. The error code is 0xc0000005. I disable AFA, and then IE11 works well. I try to uninstall AFA and reinstall it, but IE11 still doesn’t work and the error happens again. My OS is windows 7 64bit Service Pack 1. IE11 is 11.0.9600.18921. Please help me solve the problem. Thanks a lot!
