Can I make sure I've understood you properly? After uninstalling Avast using Programs and Features there's no need to run aswClear AND your tool because yours will remove everything aswClear does plus more.
Correct, uninstall avast normally then run RejZoR's tool.
Thanks. This is much more convenient than having to reboot in safe mode to use aswClear. Use RejZoR's tool instead and everything can be done in normal mode. Well done RejZoR!
