Title: Error when trying to uninstall
Post by: Zadeth on August 13, 2012, 12:49:53 PM
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.

Thanks. I'm not very familiar with Windows Safe Mode, so I am a bit reluctant to use it in case I mess something up. I accidentally ran the uninstaller and it said something about disabling self protection. How am I able to do that?

avast! GUI -> Settings -> Troubleshooting

When I do this, it automatically re-activates itself when I exit.
