have unistalled avast trial but did not restart system immediately, now have avast still sitting in the system, tried to uninstall from Program/Features (error shows up)and system backup tool as well (does not remove this), nothing helps, would you be able to help me on it?i am using vista now…
The add remove programs should have removed it, so I’m not sure exactly what you did.
Trying to remove components if avast is still installed will bump into its self-defence module to protect against malware doing the same.
Download the avast! Uninstall Utility, find it here and save it to your HDD.
use windows add remove programs to uninstall avast, reboot.
run the avast! Uninstall Utility, reboot. If step 1 failed it may be necessary to run this from safe mode, once complete reboot into normal mode.
avast should be completely removed now.
Can I ask why you wanted to uninstall after the trial ?
If there was a problem we could try and resolve that problem.
Commonly people trying avast fail to uninstall their existing AV and that can cause conflicts.
