F-secure installed but won't open UI
F-secure worked just fine at first. However, since my pc was upgraded with a new GPU and Windows11, I can't open the app anymore. I have uninstalled with the special tool, and re-installed like 12 times by now. Tried the Webview2 solution, but all to no avail. As I got my F-secure along with my internet provider, I have no…

F-secure critical error. asks to restart.
This is becoming a rather annoying recurring error. Every 5 minutes (or 2 hours if I chose so) the F-secure app asks to restart because of a critical error. The critical error suggests there is a conflict with another program, but the program listed is F-secure. So is the antivirus fighting itself? I've tried restarts.…

FS always gets stuck at 14% update progress.
The FS homepage reminds me that "your virus database has expired....xxx". When I click the "update" button, the update tab page shows the progress constantly at either 14% or 100%. I don’t know the reason for this, because my computer doesn’t shut down often. After the last reboot of the computer, I found it could work.…

Antivirus database not updating - what's wrong?
Hello, I'm not exactly a computer-savvy and rely on people knowing better than myself. I have a valid F-Secure Total subscription and the program gives an alert about every hour, that I need to update. But when I click the link, the update is failing. I have no idea what I'm doing wrong. Any ideas?

Will F-Secure ever change to a traditional UI?
Hello :) I'm wondering if F-Secure will ever change the cartoon images for a more traditional "professional" look? And I do get the idea of not being like other AV's "traditional" look, but do you ever think it's kind of a turn off for people who may otherwise consider using F-Secure? I also know if you collapse the top…

F-Secure asks me again, even if I select "Don't ask me again".
F-Secure keeps reminding me to set up the Google Chrome browser extension. I do not want to install it, so I check "Don't ask me again". How can I confirm that selection? If I click on "Set up" I go right into the setup, which I obviously do not want. If I close the notification via the "x" on the top right, soon the…

Inter i5 Mac - Sequoia 15.4 - Libre Office very bad perfomance
Hi, It seems that F-Secure Total v. 25.3 (64654) on Mac is totally ruining performance for Libre Office v. 25.2.2.2. When I temporarily disable scanning on Total, performance is ok. When scanning is back performance degrades heavily: e.g. selecting text box in Impress takes 3..4 secods, same for simply changing the slide…
