I’m thinking about upgrading Avast! but can’t find anywhere the duration of the fee. Is it a one time cost or does it expire, and if it expires, how often?
Everything you need to know can be found on Avast.com. Avast is just like any other antivirus. When you purchase it it’s either good for 1-3 years. Depends upon which package you buy. But no company offers a lifetime license.
No reason to have a poll. It expires in a year if you buy a year. Self explanatory.
All depends on the license period that you choose while making the purchase, there are 1-2 and 3 year licenses
