I see no trouble for it. Uninstall proccess for me is very fast and always faster than install.

It’s the best way to uninstall but, as you say, why uninstall? ;D

If you boot between the ‘add/remove’ proccess of uninstallation, you can use avclear4.exe without fear in the next boot 8)

How I fell bad to uninstall avast! ;D
