Avast is an antivirus program based in Prague, Czech Republic.
As part of the Gen Digital cybersecurity group (alongside Norton, AVG, and Avira), it has been offering antivirus protection for several years and is highly regarded by beginners for its user-friendly interface.
In this version, Avast has been further improved with a few tweaks, particularly to the interface.
Let’s see how Avast performs.



Interface :

In this 2026 release, Avast has revamped its interface with a new look. I like it—it looks more professional.
There are still a few prompts to upgrade to the paid version (especially during AutoScan), but we’ll let that slide: Avast offers a free version, and you can disable the “nagging.”
I also like Avast’s explanatory and educational approach, where it uses a pop-up to explain the different menus: what each one does, the shields, etc., without confusing the user.

Web protection: 9/10
Avast blocks all links except one, which is a Rozena/CobaltStrike Trojan. It won't run and will display an error message.

Fake crack : N/A
The sample is too old and the site that distributed it was down.
Skipped.

Malware Pack : 25 out of 101 threats remain
Although Avast has a good antimalware scanner and its IDS can catch some infections, it unfortunately falls short.
During the test, Avast had some bad luck with a few scripts and allowed a system process to become infected by a RAT without issuing an alert.
Even though it managed to stop a few launches, block payloads, and prevent various connections, the machine became infected fairly quickly.
Even during the cleanup, Avast displayed a detection of a blocked IP address belonging to a botnet, understand that the PC is being controlled by a cybercriminal through a botnet (hence the term "botnet").
Its firewall never reacted, even though it was enabled.
Too bad—Avast is falling behind when it comes to unknown malware!

Final scan :
Avast : 1 - IP blocked => Botnet
NPE : 5
KVRT : 10 - Memory infected

Final opinion:

Overall, Avast remains a reliable antivirus with solid protection features.
However, if it’s pushed to its limits, its proactive defenses fall short and won’t be able to protect you effectively.
If you browse the web cautiously or securely, Avast is a good choice.
But if you engage in risky browsing, you’re better off looking elsewhere.
 
Thank you for the test @Shadowra

May be it lacks Hardened mode (or Cybercapture, cannot recall which one) compared to Avast "regular"?

Yeah, you're talking about Avast's "Hardened Mode."
It turns Avast into an "Anti-exe," which blocks any programs without signatures.
Good for a beginner, but pretty aggressive too :p

Of course it is not related to missed detection of scripts.
The only cure with all AVs is CLM and restricting script file execution outside system area.
 
@Shadowra in light of this: "If you browse the web cautiously or securely, Avast is a good choice. But if you engage in risky browsing, you’re better off looking elsewhere". What are some of the elsewhere's you'd suggest, for those who may wonder, besides just practicing better browsing habits as you alluded to? TIA :) And as always, another wonderful review :)

Bitdefender, Kaspersky, Eset ;)
 
He has no Containment... She is sick of his messes... She dumps him and happily moves in with Comodo! 😊
The role of containment is not questionable; it is a respected mode of protection; just I feel it perfamce taxing more than the protection it provides for low-risk users, such as me.
It is a matter of feasiblity study.
 
You hurt McAfee's feelings.
At least with the 3 Shadowra mentioned, they are quieter than McAfee (for some). There were about 3 - 4 of us that uninstalled McAfee due to pop up, up sell notifications in the right hand corner of our screens. I'm sure Avast One will have its share of upselling, left hand side, while Avast Free main UI is cleaner looking when you disabled some of the Notifications etc. settings.

When do you start calling them 'useless', 25 left, 35 left, 45 left, i wonder. Just because it has a reputation, ,doesn't mean it deserves praise.

For anti-exe's you never call them effective and shun them into a corner, just because you don't agree with the concept. Default deny is a valid security concept and the bottom line is that they also keep you safe. As some communist leader once said 'white cat, black cat - if it catches mice then it's a cat' .

When I write about it, my friends in the US say kaspersky stealing information, but Kaspersky is the king of this business. It has transparency and consistently top-notch protection. It's lightweight and offers excellent protection (I'm not Russian 😂).
Most prabably all steal; the only difference is where the stolen goods are going.
Unless they are going to steal my credentials, I have no problem if the product is free.
 
Thanks, shadowra once again,are you still using Eset Internet Security and Cyberlock, if I remember that was back awhile maybe 2021 Just wonder with your tests, If you have changed your computer configuration ?

Yep I have changed
Have you found ESET to be quite effective against fresh, zero-day samples?
The database and its cloud are very effective. (In my opinion, better than Avast)
But the HIPS needs to be configured.

I never said I was setting these Anti-Exe systems aside; I'm just not as big a fan of them. And a beginner wouldn't touch that ;)
Still, I might try out the Hardened version of Avast someday.
