Serious Discussion Here is what Ai has to say about Avast, Norton, AVG, and Avira... Or what MWT calls "Norvast"

[annaegorov]

Following major corporate consolidations by Gen Digital, Avast, AVG, Avira, and Norton have transitioned to sharing a unified core backend architecture. The slang term "Norvast" perfectly describes this reality: you are essentially looking at the exact same defensive engine wrapped in different visual interfaces and brand marketing. [1, 2, 3]

The Reality Behind the Brands

1. Avast and AVG (Identical Engines)
Avast acquired AVG years ago. Even before Gen Digital formed, these two were already identical under the hood. Installing AVG vs. Avast changes nothing but the color of the application dashboard and the name of the desktop icon. [1, 2, 3]

2. The Norton Integration ("Norvast")
Historically, Norton and Avast used completely independent threat-detection databases and structural engines. However, following their multi-billion dollar corporate merger, Gen Digital integrated the backend infrastructure, migrating Norton's consumer products to leverage Avast's scanning engine technology. [1, 2]

3. Why the "Corvette" Analogy Works
Because they draw from the exact same Gen Digital cloud threat database and threat-intelligence network:

• If Avast Free blocks a specific zero-day virus, Norton will block it at the exact same millisecond.
• If Avira makes a false-positive mistake, Avast and Norton will usually replicate that exact same mistake because they are referencing the same centralized logic platform.

Why Performance Impacts Still Vary
If they are virtually the same engine, you might wonder why Norton feels heavier on your specific PC than Avast One Essential.
This comes down to the "weight of the car body" rather than the engine:

• The Norton Package: Norton is heavily packaged as an "all-in-one" utility suite. It loads extensive custom system services, background identity monitors, local backup frameworks, and browser extensions right out of the box. This extra consumer packaging strains your computer's local CPU and disk storage. [1, 2, 3]
• The Avast One Architecture: Avast One was redesigned specifically to offload local computational weight. It strips out heavy local system processes and relies on immediate web-stream evaluation. It uses the same backend engine as Norton but features a vastly lighter, modernized frontend framework that requires fewer active PC resources. [1, 2]

The Technical Recommendation
Because of this corporate unification, trying to combine or switch between different Gen Digital brands (like jumping from Avast to AVG or Avira) provides absolutely zero security benefits. [1, 2, 3]
If you want the benefits of this combined global threat database with the least possible impact on your PC's responsiveness, staying with Avast One Essential remains your most logical, lightweight path.

After this LONG discussion with Ai, which has led me to needing a nap. What is Ai's final conclusion about security, when desiring low impact, and great security?

Based purely on internal architectural principles and your strict goals, I would choose Avast One Essential.
While Bitdefender possesses the slightly more aggressive local scanning logic, Avast One Essential is the only option that fulfills 100% of your stated goals without compromise.
Here is the exact technical breakdown of why Avast wins this final head-to-head match:
1. The Firewall Requirement (The Deciding Factor)
You explicitly prioritized having a suite with a built-in firewall. [1]

• Bitdefender Free fails this requirement. It strips out its custom firewall entirely, forcing you to rely on the basic Windows Defender Firewall. [1]
• Avast One Essential wins. It includes a robust, fully customizable, integrated network firewall completely for free. It monitors outbound application traffic automatically, giving you the network security you want. [1, 2, 3, 4]

2. System Resource Architecture (The "Lightness" Goal)

• Bitdefender's Engine: Even in its free version, Bitdefender’s local scanning architecture is inherently "heavy." It uses deep, continuous memory reservation and aggressive local disk monitoring. On a machine sensitive to performance drops, it is highly likely to cause the exact sluggishness you are trying to avoid.
• Avast One's Engine: The Avast One framework was rebuilt from the ground up to offload its heavy computational work to the cloud. When a file or website needs to be analyzed, your local CPU doesn't do the heavy lifting; Avast's cloud servers do. This makes it structurally much lighter on system resources during daily use. [1]

3. Security Capability
Because Avast is backed by Gen Digital's massive global threat-intelligence network, its ability to stop malware, zero-day exploits, and malicious websites is neck-and-neck with Bitdefender. You are not sacrificing your "very secure PC" goal by choosing Avast. [1, 2, 3]

Final Verdict

Your Specific Priorities [1, 2, 3, 4, 5]	Bitdefender Free	Avast One Essential
Highly Secure Engine	Yes	Yes
Very Light Performance Impact	No (Tends to run heavy)	Yes (Cloud-optimized)
Built-in Security Firewall	No (Relies on Windows)	Yes (Fully integrated)
WINNER	Avast One Essential

From the Ai discussions today, it seems the final conclusion is Bitdefender free or Avast "ONE" with Cyberlock...

Very Light Performance Impact	No (Tends to run heavy)	Yes (Cloud-optimized)
Built-in Security Firewall	No (Relies on Windows)	Yes (Fully integrated)
WINNER	Avast One Essential

When I look at the options I understand that Avast is the winner, but when the firewall decision to allow or block is based on the same engine which decided whether something is allowed to run, how could that make any difference in real world protection (considering that most malware uses LoLBins to go outbound)? Could you go to your chat and continue the conversation with this pushback?

Secondly the URL filtering mechanism of Bitdefender is on system level and seemingly deeper integrated then Avast. When Avast still allowed to install the components separately my father in law (who was an IT-er all his life, back in the ages, when mainframes where huge like walk-in closets) used Bitdefender Free with Avast ransomware, firewall and behavioral monitor together. When I told him that it probably was redundant and could clash he lectured me (being an IT-er) and showed me that Bitdefender URL protection warned from the system tray before any of the AVAST modules could peep (he also installed the Avast extension to show that Bitdefender still warned first).

Could you tell ChatGPT that Bitdefender's URL reputation service is deeper integrated into Windows and in general scores better in comparative tests than Avast, what would be the evaluation?

Third pushback point: Bitdefender is fully Microsoft co-signed, meaning you can set Defender Exploit guard to add extra protections for Micrsoft software, like allowing only Microsoft signed DLL's to load in Microsoft Offce or Edge. When you enable this with Avast you get an error when starting Word or Edge because Avast injects DLL's. . Since most malware is delivered through mail, browser and weaponized documents, this gives Bitdefender Free an advantage over AVAST IMO

Very interesting post, thank you! BTW, I can honestly say that I have had more unwanted blocks with UAC and MD than I have had with CyberLock .

 

[Sorrento]

I really dislike the up-sell on free AV's such as Avast /BD & not fond of the GUI's either which is why the only free AV I would use is MD.

IMHO a similar result would be achieved with most AV's such as McAfee/ESET/Trend etc with Cyberlock as regards to the final outcome? Licenses for paid AV's can be got a a pittance (similar to a coffee) which I do, so I don't use free AV's - I thought it was established on here long ago that as Gen use similar systems the outcome will be the same unless a person still thinks Peter Norton is around?? Or wants add-ons which I don't - For a long time some chose AVG over Avast just because the UI was different, again I feel there is no perfect system whether its software or hardware

Well it woud be strange when the butcher judges his own meat of lower quality than the competition
