Good morning, hello, and welcome to Avast Forum I<3Avast
I have been using Avast Free Edition since the release of version 7 and till now using it. I won't let go of Avast Free Antivirus every again
. I can tell you from past experience it is the BEST free antivirus out here. It really works well with computer using less system resources, lightweight, and the list goes on and on. Just remember NO antivirus is 100% in detecting malware the best way is to use other malware protection such as Malwarebytes Antimalware.
If you need support for your Avast Antivirus Free Edition you can post them here and it's all for FREE
+ support from here is one of the BEST support you will ever receive
It is really good that you use Malwarebytes. Do you use SuperAntispyware Free Edition as well? May I ask what other cleaning software do you use?
