I found that “follow links” during a scan is a bad idea.
I use “scan in order found on HDD”. This seems to speed up scans.

PUPs are not necessarily bad. Some PUPs are good, some aren’t.
PUPs are disabled by default due to the fact most users wouldn’t know good from bad.
Weekly quick scans are plenty. avast has real-time shields for better protection, which means frequent scans are not necessary.
If your daily “multi-scans” come up “good” that is a sign you are over-doing it.
Allow avast to populate the persistent cache for quicker scans in the future.
For “boot scans” just use the default settings.
Too much tweaking leads to disaster.
Too many scan means you are using too much computer resources.

I do a “scheduled” weekly quick scan and a full scan once a month if I remember to run it.
My full scan is “not scheduled”. So sometimes I go five weeks or more without running a full scan. :slight_smile:

edit: Boot scans should “only” be done if avast recommends doing so.
I haven’t ran a boot scan in years.
