Google Chrome Portable 100.0.4896.88 Stable

Hi,
1.) The search for harmful software feature doesn't work I receive the following message.
**In Settings > Privacy & Security** (Heading in the category list on the left column of the pg.)
|
**Safety Check Section** (1st section of the Privacy & Security category page)
|
**Device Software**
|
**Find Harmful Software**
**Search Failed:**
*An error occurred while Chrome was searching for harmful software.*
How do I make the 'Find Harmful Software' feature work?

2.) I have some additional questions that aren't related, but would like some input.

**In Settings > Privacy & Security** (Heading in the category list in the left column of the webpage)
|
**Privacy & Security** (2nd section of the Privacy & Security category page)
|
**Security Section**
|
**Use Secure DNS**
2i.) *Which secure DNS provider is best?*

2ii) *Do any of the DNS provider options use the DSEC Option?*

2iii) Does the Chome need to use the ISP provider DNS on the first query of an internet session regardless of whether this setting is chosen?

3.) **What are the best options for protecting against malware, privacy invasion & DNS tracking, spoofing?**
*(Initially I was thinking about an extension, but all suggestions & info are welcome.*

*Sorry, I couldn't find a current Chrome topic to post under.* Ugg!

**Thank you for your time & consideration!**

Phill

P.S.
When clicking on the 'More Information about text formats link' immediately below the post creation box; a user is directed to the https://portableapps.com/filter/tips pg. The choice for making text appear & the option to indicate text doesn't seem to work in the post preview area. However in this post script comment, the text after &, did appear bold. The Text format setting was left in the default option, 'Basic HTML and Text'.
