ps: you're wasting everyone's time here, the OP's for advising him a useless procedure, and my own time for spending a minute to write this post here. I mean why not run the uninstall utility ten times, just to make sure there's no registry remnant, and why not format the HDD after all 
And you are OT, instead of solving this by
PM. You are quoting a post from yesterday, when aswclear7 was not fully ready. You are also wrong about one run of aswclear. During the (pre)beta tests, more than one user actually succeeded with the second run of aswclear, but not in the first one. When you uninstall a driver in Windows, the "previous version" is placed instead, after the reboot. When a user has used previous versions of avast, he would need to run aswclear for each and all versions of avast ever installed and/or updated to, so to prevent the same component from being still a remnant after the reboot. Please stop being a bully. If there is something wrong, then give a reason instead of freely trashing people's names without technical reason nor need. And for OT, there is PM.
My apologies for the users that are interested in solving their problems, both for the OT and if the reinstall didn't work.
