2022 MacBook M2 + BitDefender not detecting hijackers - why?

I have a 2022 MacBook M2 running on Sonoma 14.6.

I have had Bitdefender Central & VPN installed for over six months.

1.Trovi

Some weeks ago, after regularly being stopped from browsing by ‘Trovi’ when using Chrome,  I deleted the browsing history, removed Chrome & re-installed it. Trovi is no longer stopping me browsing but I found there was still malware of a different variety (see2 & 3 below). 

At no time did Bit Defender detect Trovi despite me running full scans several times a day after each update.

2.BitDefender

Immediately after an update from BitDefender I usually run a full system scan that always gives a ‘no threats’ result.

I recently ran a free scan by Combo Cleaner that notified me of two hijackers on Chrome.

Type: Spam Ads.          Name: fastsolve.captha.com

Type: Extension           Name: MyShopSearch {VER.1]

I then selected BitDefender Adware Removal Tool (B in tool bar between XLS and C) and 

‘Search for Adware’.

It tells me that Genieo is present. I used the tool to remove Genieo, removal was confirmed but soon after it reappeared. 

The twice daily BitDefender scan I do has never detected any of the threats noted above.

The BitDefender VPN does not connect automatically and if I try and do it manually I get: -

3. Avast Security

I ran a free scan with Avast Security that gave a ‘no malware found result’ but a notification of ‘advanced issues’
