I've just installed the new Avira Antivirus Pro v126.96.36.199 (virus definition 188.8.131.52)
It's detecting a bad thing: DR/Autoit.haroo into the 6.041 AdwCleaner file (consequently sent in quarantine).
Are you aware?

This "problem" is not up to AdwCleaner...
The problem is that Avira detects Adwcleaner wrongly as Malware. This is a false positive by Avira and has to be fixed by Avira.
it seems that Avira has already fix this false positive.
