Yeah Avast has really gone bloatware downhill. It was speedy and had a small footprint back in the day.
I've been using Windows Security exclusively for about a month and it's been fine. No issues. The only annoying thing is the ransomware protection pop up that comes up when running some applications. But that's it.
I think Kaspersky is very good but it's also become very bloated and gets in everywhere on your computer. They have pop ups for their VPN, password manager, their sandboxed window for financial sites, etc.
