I use the free version largely because of it's simplicity. I don't want a lot of gizmos and gadgets. It is a wonderfully trouble free experience and has been for many years. I am very grateful for it's existence.

I had recommended Avast™ to a co-working friend because he said his computer was running slow. He said he ran the anti-virus twice and his computer speed improved.

I have used Avast™ for many years. The reason is very simple. You offer a great free version that actually works. This lets me afford the other amazing service's you offer when needed like Avast™ clean-up.

Avast™ free antivirus does what it is supposed to do without much fuss. Though I would prefer fewer popups.
