Welcome to avast and the forums Puskin42.
Welcome to the forums, pushkin42.
Yes, all of us users will agree with you on how much better it is than other av programs. I am sure the developers & everyone at Avast will appreciate your thanks.
Please come back often, learn more, and maybe help others.
I have been using avast since some months ago, and I love this antivirus program, I think its better (for me) than norton, kaspersky, or any other.
I will buy the pro. version next month, as a way to give thanks to the developers.
