I bought a one-year subscription to this for $9.99 a few months ago replacing Avira.
I like the this and it seems to do the job. However, I am getting an awful lot of popups despite paying for the software and using a popup blocker. It is a little annoying to get these a number of times during the day and they are really just ads to get other products or extend my subscription.
One good thing about this is it doesn’t seem to be using a lot of computer resources, compared to the likes of Norton, but I wish they would eliminate or at least reduce the ads after you already subscribed.
