I have trusted Avast for my security needs for many many years but today I am writing this comment because I need to warn others.
DO NOT INSTALL DRIVER UPDATER
It crippled my machine: USB3 ports no longer work, SSD goes to sleep and will not wake up, printer is recognised but errors on print. I am working my way through the damage but for a paid-for product this is shockingly bad.
AVast, I understand the business driver to increase your product offering and revenue streams, but this has made me question whether I can trust your products any more.
