Thanks for the free AV , but this is unnecessary .
Yes it is.
avast is a commercial company.
No. A commercial company is ‘free’ to charge its users for the products it sells as long it advertises them for what it is , but this is deception.
No it is not a deception.
It is a gift.
You are offered up to 30% off if you buy something.
Like a discount coupon.
Sorry but a gift doesn’t have a price tag.
It’s misleading and should be changed to say that it’s a special offer with a large discount on a paid version.

Couldn’t agree with you more.
The gift is the discount coupon, it doesn’t have a price tag.
The reality is “buyer beware” in everything. There is always a gimmick!
Read everything carefully and only submit to what you understand.
There’s no deception once all information is considered.
