If I understand your question correctly, you are asking about options for a 3rd-party anti-virus (or security suite)?
That is a common question with no correct or best answer to suit all computers, users, budgets.
If there were, then there would only be one "brand" on the market.
There are many fine options, both free and paid.
Aside from Windows Defender (under Win10), most/all of the "free" AVs come with hidden "costs", such as reduced features, reduced support, toolbars/bundled software, nagging ads to upgrade, etc.
The basic approach often suggested for home users consists of a layered approach to active protection:
ONE real-time, robust AV
ONE real-time anti-malware
ONE real-time anti-exploit
Other layers (hardware/software firewall, custom hosts file, etc.)
Having said that, no security program or group of programs can protect 100% of computers from 100% of malware 100% of the time these days. The most critical security component remains the one between the chair and the keyboard, through safe computing practices, aka "safe hex".
>>WHATEVER you do, however, I suggest that you NOT obtain ANY security application or other software from cnet.
It is notorious for bundling all sorts of PUPs, wrappers and other crapware with their files.
There are a few "safe" third party software hosting sites.
>> But, as a general principle, it's ALWAYS advisable (safer) to obtain the installer for your AV, AM, other security apps (or any software) directly from the publisher's own website.
