Can't Uninstall Avast
« on: August 13, 2015, 05:13:57 PM »
A few days ago, shortly after updating Avast to the latest release, I started getting an error message pertaining to Avast whenever I'd boot up my computer. I tried opening Avast to see if something was wrong but I'd get the error message again. I've tried uninstalling Avast to see if reinstalling it might work, but I get an error message when I try that. I downloaded a program called avastclear which was recommended to uninstall Avast and I get the same error message. I have tried starting my computer in both safe mode and safe mode with networking and tried uninstalling and using avastclear. I don't get the error message while in either safe mode, but my command to try to uninstall or use the avastclear program simply get ignored. I downloaded CCleaner and ran that, correcting any errors found and still can't uninstall Avast. I installed two different malware scanners (Emsisoft and Antimalwarebytes) and ran both of them, removing all malware found, and still can't uninstall Avast. I figured since Avast isn't working whatsoever, I needed a working anti-virus program so I installed AVG free. My computer apparently registered two AV programs and stopped working properly, such as refusing to open any web browser. I removed AVG and won't be trying that again. I am without a working AV program so I'm reluctant to do much online at all. Can anyone help me? This is the error message I get every time I try to uninstall Avast or use the avastclear program.

You must run this fix from safe mode or it will fail

After the reboot run Avast clear from normal mode

Attached is the fixlog, as requested.

After running Avast Clear, it said Emsisoft was a conflicting AV program and needed to be uninstalled, which I did and then restarted my computer. Am I now able to install Avast?

Yaaaaaaaaay, it's working again! I spent ALL DAY yesterday trying to fix it and felt completely useless when absolutely nothing worked. I think it goes without saying that I never in a million years would have figured this out on my own. Thank you, thank you, thank you!

I think that it was A2 that was complicating matters

Remove tools

Download and run Delfix

I don't even know what A2 is, but I'm so glad you figured it out. I just downloaded and am running the program now that you recommended.
