I had to format my PC today after using Avast for 3 years. On the old version it was easy to see where you set the scheduled scans but it is nonexcistent in 2016. Where is the option at? When I originally updated from 2015 to 2016, it would just scan every day at 5AM like I originally told it to 3 years ago but now I have to reset all my options again and I cannot find this one.
Whilst it is possible to schedule a daily scan in avast 2016.
With a resident on-access antivirus like avast, the need for frequent on-demand scans is much depreciated. For the most part the on-demand scan is going to be scanning files that would be otherwise be dormant or inert. If they were active files then the on-access file system shield would be scanning them before being created, modified, opened or executed.
I used to have avast set to do a scheduled weekly Quick scan, set at a time and day that I know the computer will be on. But I have ceased this practice for some time now, based in the above.
Both replies are appreciated, thanks for helping me. I would rather do a weekly scan at least just to be safe, I am fairly paranoid and I am very active online, and even though I take a lot of other precautions I’d rather not be the victim of carelessness. Ever since I started using PeerBlock though neither avast o malwarebytes have picked up barely anything dangerous.
Sorry if I was a bit short, I had just got done erasing 6+ years of history and all that remains of it are a few essential backups, plus I spent 5 days after that trying to figure out what was wrong with my hardware… It happens, but it sucks when it happens to you.
