I am using Windows XP Home. I did as instructed, went to Administrative Tools>Services, and found one of the two files labeled Remote Procedure Call set on Manual. I changed it to automatic and restarted Windows.

Left clicking the on-access icon and selecting start runs through memory check successfully, then opens the simple user interface and Avast screen, which shows that resident protection is disabled.

Left clicking the on-acess button opens a popup with the message “avast!:The AAVM Subsystem detected a RPC error. The operation could not be completed.” A button at the bottom is labeled OK.

I still can’t set resident protection.

What do I do to fix this?
