This is the free version of Avira:
I just noticed they don’t actively mention it on their current website when you click on the Home area. They used to, but I fear too many weren’t paying for the upgraded versions.
That said, there is one annoyance with the free one—when it updates the software, an ad for Avira pops up in a browser window. You click on “Okay” and it’s gone.
I was able to get the next version up for 25% off, so I upgraded recently and got rid of the once-a-day ad.
I dl’ed Avira. I saw the pop up, but for free I thought ‘big deal’. Just clicked ‘ok’ and it went away. Have both AVG and Avira now.
