I’ve tried rebooting, re-downloading the patch, updating through avast “update program” interface, scannning the PC for threats with both avast and malwarebytes, running as admin, etc… no change.
My system is very similar to Rayn’s running Win7 64bit SP1.
Yesterday the update from Version 6 to Version 7 didn’t conclude properly and Avast wouldn’t work.
So I went back to an earlier Restore point and now have Version 6.0.1367 back again. Unfortunately this isn’t working either.
The Fix Button doesn’t work. The Start Program button doesn’t work.
The Shields are all disabled. If I try to start them the message is Shield Unreachable.
If I try to update either the virus definitions or the program the message says that the Avast Service is not running.
If I go into Settings-Troubleshooting the Self-defense module will not turn off.
On the Subscription page no licence details are showing so I tried to insert the license file (license.avastlic) and receive the message No Valid Licence Content Found.
So I thought I would try to uninstall the program and do a reinstall. That doesn’t work either.
Unistall doesn’t work from the Control Panel and the message says Error reading Product Data. Set up cannot proceed.
I downloaded the uninstall utility aswclear.exe. When I try to run it from Safe Mode it doesn’t work and the message is Not a Valid Win32 Application.
