Serious Discussion F-Secure - General discussions

F-Secure has stabilised a lot in the recent months. First few months were terrible after the new changes, used to get tons of false positives and constant CPU spikes while using torrent client. Now, there are lesser FP's, exception function actually works and zero CPU spikes while torrenting. I have another two months of subscription left, will decide on Kaspersky or McAfee at that time.

That will give you enough time to see if the changes with v25.9 are enough for you to consider staying with F-Secure. Otherwise, those are two other good choices to consider when that time comes :)

F-Secure (not the same as WithSecure, which is its "sister" company and shares the source code and agreed-upon resources) is struggling. I think WithSecure is doing even worse. Don't be surprised if one or both are purchased by DenGigital or even Natalia Kaspersky's InfoWatch.

I will be surprised if F-Secure and WithSecure exist as standalone companies 5 years from now.

F-Secure got rid of a lot of personnel, scuttled internal development teams and technologies, and then purchased Avira modules to replace both the people and the technology. Mikko Hyppönen is long gone under the guise of "Wanting to expand my horizons" and "Drones are the future."

F-Secure and WithSecure have entered the death spiral stage. Now it is just a matter of time. And waiting. How long will it take? Maybe quickly. Perhaps slowly. But it will happen.

Despite all that, F-Secure stable (not beta or insider builds) seems to be plain old vanilla ice cream AV, with perhaps a sprinkle or two.

Lately, the English forum gets very little attention compared to the Finnish side. Firmy (English community manager) hasn't posted since Aug 14th.
But, I do like sprinkles 😅
 
Sad but true, I would go McAfee Total and get the unlimited VPN as a bonus, and that all with a very cheap price tag, as seen here on MWT.com

10+ years ago it was one of the premium AV's & was never found cheap at least here.
F-Secure is now just Avira with a blue Finnish skin, with perhaps a few vestigial F-Secure technologies or features.

The F-Secure and WithSecure share prices at 0.75 Euros per share are far more interesting, but the products themselves - well - they're decent products. Not the best, and certainly not the worst.

I don't understand what the big disappointment about F-Secure is. It's feature set was never top-tier. It was always a second or third tier product.

The fact that it was expensive in cost only meant that it was way over-priced compared to AV leaders such as Bitdefender, Kaspersky, and Norton.

F-Secure has always been a "boutique" AV, so it does not have economies of scale and therefore its expenses are much higher than the industry average and the company just passes on those higher costs to consumers. Same with Avira - which is only really popular in Deutschland - and everything there is expensive.

F-Secure today is worth about 15 Euros for a 1 year subscription for 3 devices.
 
It was reported on the F-Secure forum that the latest Edge update may have broken the functionality of the browser extension, as well as some other misc. extensions? Everything is fine on my end, though 🤷‍♂️
The resolution for the OP's issue was a complete uninstall and reinstall of F-Secure.

Needless to say, the OP was not impressed with F-Secure's forum support, and rightly so. On the English side, you may as well contact the other off forum Support options first. On the Finnish side of the forum, it's a whole different story, as they seem to take care of their own.

Just yesterday tried to update Glasswire. Ran into a problem: F-Secure detected it.

But upon looking closely, I saw it was "Evo" detection. Not sure what it means, but since Avira is part of Gen digital, something regards to that?
Reminded me of Fighting malware with machine learning

The Evo label comes from the Avira engine now used by F-Secure. It’s a detection system based on machine learning, which flags files for suspicious behavior rather than relying only on known signatures. In your case with Glasswire, it was most likely a false positive during the update.Here’s some information about this kind of “false positives” that might be useful to you. 👍😲

I just installed the Free version 3.8.1033. It wasn't detected on install, and in doing a restart then running a Quick scan, either. I'll see if anything happens on my end, if Behavior Detection flags it or not, since I installed the latest version (it wasn't an update). Otherwise, maybe one of us needs to report it to F-Secure, as a FP, like @Halp2001's link, @Khushal post shows.

edit: It looks like it was a short lived FP. No longer being flagged by Avira.

Had to be quick gen as if one engine detects all its dependents also suffer and i had to call them out. No response from Mcafee yet.
 
U are safe my friend i did not find any sus behavior in VM however it could be a ticking time bomb being shy and holding onto its payload.
I'm uninstalling it anyway, as I just installed it to check things out on my end :) Thank you for that concern, my friend :) :)

edit: but, I'd like to think Behavior Detection would pick up on it, if it were timed delayed malware :)

I was concerned to see the red flags so i tested it on a battlehardened VM. Safe to assume as of now in the half hour i looked at its behavior that i couldn't find anything untrustworthy... That's why i posted with false posiitives link.

Just an aside that was included in a little chat I had with Gemini Plus today.

The data from the March 2026 Malware Protection Test is particularly impressive. For a suite to go from 48 False Positives (FPs) in some of the previous years results, to just 1 FP in the latest report is a technical "redemption arc."
  • Why the FPs dropped: Historically, F-Secure’s "remarkably many" FPs came from an over-aggressive cloud-heuristic engine. In 2026, their shift to the Behavior Detection engine (the one in your screenshot) is clearly more "discerning." It is looking for what a file does rather than just what it looks like.
