I use Novabench to check the performance score of systems with antivirus installed, in my test, the best and fastest for my system was Microsoft Defender, my games and browsing are fast, and as it has good protection, I'm satisfied
Same here; I've tried just about everything, and it really seems to be the most smooth-running with Defender.

Thank you for your detail answer, but I have a question: why Avast One Basic, not Avast Free?
Well, to start with I just like the GUI better in Avast One. I will admit though that it has taken me a very long time to be able to say and believe that. When Avast One was first introduced I did not like the GUI at all, I thought it was too cartoonish and cluttered. But I am OK with it now. I think Avast One is the better choice because not only does it have very strong AV protection, but there are also privacy and security tools that I can actually use. The VPN for one, I have never been a big fan of VPN's but I may start using the free one in Avast for online banking and bill payments. With all the criminal stuff happening online now I really feel like I can't be too careful. There are other good tools in Avast too, it can help identify problems with passwords, software that needs to be updated, it has good privacy and security tip info, and it can clear browing history in one click. I also like how Avast now has a setting where you can turn off the upsell nag notifications.

For my use, Avast One just seems to be a more modern, complete and advanced version of Avast Free Antivirus. I know the AV test site reviews need to be taken with a healthy grain of salt, but Avast and AVG consistently get good scores and reviews. I read good things about Avast here on MWT lately as well. Plus I was already using the free Avast One AV on my Pixel 6 phone, so I had a pretty good idea how it would work on my laptop. Avast One is the only free cell phone AV I have ever found that actually runs in real time and works a lot like a computer AV. I have never had any trouble at all with Avast One Essential on my phone.

I also think that Gen Digital must surely have the staff, technical ability and financial backing to address any problems that might come up so they can keep Avast updated and effective. Here is a link to just one of the sites that helped me in my decision, it's from 2023 and details Avast One Essential but the info still applies to Avast One Basic and Avast Free AV:

Norton used to be very light on everything. Low memory usage, low CPU activity, low disk usage, pretty much no slowdowns. Unfortunately, as Symantec engines are going away, it now has a sheer number of processes, just like Avast. Optimisations are gone.
Do you know if the current V22 will coexist as an option for customers for once V24 is rolled out fully?
And the follow up questions would be for how long, and if the quality of protection would be reduced due to lack of any further development?

Once the wide deployment of the v24 is complete, 22 will be discontinued. Norton is not taking the upgrade lightly and is deploying it in a highly-controlled manner. The V22 will be offered for at least 5-6 months more, when feedback on the V24 will be mostly positive.

There is no lack of development, Symantec/Broadcom in partnership with Accenture will continue to work on the STAR protection framework, as this framework protects Fortune 500 companies, not one or two of them. Symantec would either have to pay Norton royalties or give up on certain technologies (most likely the former).

I just checked and there are eleven Norton processes showing in Task Manager. However, it's been very light in the week or so I've been using it, so I don't care about the number of processes.

The antivirus should be balanced, but if it is to be light or heavier, I prefer it to be light so that it does not burden the processor and does not slow down the system.
and by the way, I personally use system AV with Hard_Configurator + Configurator Defender hardening and it suits me best.

But then beware software that is too light as well. Such software excludes a lot of actions or processes from monitoring, or simply said, doesn’t do much. Examples: Panda, K7, Webroot. All very light and quiet, all not very capable.

Such software will be ok to detect prevalent, widely known malware but against 0-days and sophisticated malware (code signing abuse, exploits, fileless, etc.) will be inefficient.

These light antiviruses are very useful for home users like me (which do not use torrent, do not browse illegal internet pages). In addition, I find the k7 successful both as light and protection.

Some might argue that some solutions do not offer protection against sophisticated malware due to the absence of particular security components. For me, web protection is the most important aspect of any security solution because it is the most used attacking vector. This is why I am using MB.

That’s why the market has many offerings, for everyone to make their choice. K7 is in the cyber security industry 30 years and has only one patent, compared to others that have hundreds or thousands. It is clear K7 didn’t pioneer anything. The firewall left few open ports on my scan (7 to be exact) whilst the IPS/IDS are just “to register that they are offered” covering some super old vulnerabilities nobody would experience anymore. The antivirus engine even after MAT is so-so as we saw on Shadowra’s test recently as well. Behavioural blocking is abysmal, almost not there. Web blocking is poor.

For me personally, if I will be installing a door like the one below, I would rather not install anything whatsoever. But again, the decision is personal.

Ideally, an antivirus software should be light on all three: CPU, memory, and disk. However, striking a perfect balance is challenging due to the complex nature of threat detection. A CPU-heavy antivirus can cause noticeable lags and performance issues, Insufficient memory can lead to system instability, slowdowns, and program crashes, an antivirus that consumes a large amount of disk space can limit storage availability and potentially slow down file operations.

A well-optimized antivirus will balance protection with performance, ensuring your computer runs smoothly while staying secure.

MBBG is not equivalent to MB web Protection.

The difference is that the Premium product blocks threats system-wide and was amongst the first (not saying THE first) to implement that. This has many benefits, preventing malware from being downloaded, but also, potentially disconnecting malware that’s already active.

Browser Guard just works in the browser. It will prevent malware from being downloaded and phishing/scam but it will not assist in blocking active infections communication.

That being said, Malware Bytes does NOT initiate remediation when there is connection to a malicious host, so overall, solutions like Avast Web Shield, BD Online Threat Defence and Check Point Anti-Bot are more robust.

I would agree with this statement. The fastest for me to this date are K7, Panda, and Avast Free, with Avast probably being the safest one for security.

Personally I am not a fan with Avast one. I have not even tried it before. I just do not like the logic behind it. I prefer the Premium version and I choose what compnents to install. I do not need all the crab bundled with it. I have a VPN of my choosing and I do not need a system optimisation component. The moment Avast/AVG decide to not allow us to choose what components to install, I'll ditch it without looking back.

Regarding Avast system impact, it is indeed one of the lightest. It is a well-balanced security product. I love the fact that it allows you to customise its protection level and acheive the best performance. The default settings are great. I just enable Hardened Mode and set the Ransomware shield to Strict with protection to all file extension in protected folders.
