From the last release of nod32, the daily updates takes a lot of time and slowing my computer. I never had this problem with the previews releases.
Because I'm not the only person who reporting this problem, it's meaning there's clearly a problem with the last release.
I choose Nod32 from 20 years ago because it was light. My licence expire in august and I'm not sure to renew it if the problem is not resolved
