When trying to uninstall, I always get this message:
"The instruction 0x54498a12 referenced memory at 0x03e64000. The memory could not be read.
Click OK to terminate the program"
Is this a known problem and how can I fix it? I uninstalled Avast! on my laptop yesterday to install Microsoft Essentials, after being advised to by a computer technician. I am trying to do the same on my Desktop this morning and this error message pops up. I tried repairing Avast! and uninstalling, and nothing.
