Frequently Asked Questions

Can I use F-Secure Mobile Security for free on my Android device?
high

Based on recent user reviews, the free version appears to be unusable. Multiple reviewers report that the app blocks access to basic scanning functions with a screen that forces you to sign up for a free trial (which later converts to a paid subscription). Former users of the old 'Lookout' app report it no longer functions as a free antivirus scanner.

Source: user_reviews

What is the price of F-Secure Mobile Security?
medium

The app is free to download. However, based on user reviews and app metadata, it requires a paid subscription to use. One reviewer mentions the yearly price is $59.99. The app was previously known as 'Lookout Life' and offered free basic features, but based on reviews, that is no longer available.

Is F-Secure Mobile Security safe and a good antivirus?
medium

The app is developed by F-Secure Corporation, a well-known cybersecurity company. Its description includes robust features like a virus scanner, safe browsing, and identity theft protection. However, recent user reviews are extremely negative about the user experience because of a forced subscription prompt. The app's overall Google Play rating is 4.2 stars from over 1 million reviews, suggesting that paying customers may have a positive experience, but our sample of recent free users is highly dissatisfied.

How do I bypass the free trial sign-up screen?
low

Based on recent user reviews, there is no reported way to bypass this screen. Reviewers state that force-closing the app does not work. If you are looking for a free-only antivirus scanner, users in our sample suggest this app may not be the right choice.

I've been using lookout on my devices for 2 decades. Whenever I wanted to be sure I could open it up and do a scan. Now, for the past month, it is almost always unusable. When I open it up, the page that pitches the paid version obscures the functional page, so I can't run a scan. I guess they think annoying me is the way to make a sale. In the past, I have considered paying. Now; NEVER.

After many years of trusting Lookout for free, and after a new company took over with high disappointment I am obliged to engage in a free trial and then be charged if you continue. They in an "aggressive" manner don't let you even have the free trial without entering all your info plus payment method; you can't leave the screen. This is unbelievable. I was very satisfied with Lookout, but not now that they not consider who has it for years without any notice that the app is not free anymore.

As many people point out, you can't even access the interface without signing up for the free trial. This is the WORST development of any product I've used - Greed run rampant. If you can't support a free version, don't offer this junk. The app also randomly stops now, I suspect just to force users to the impassable "buy" screen. I have to trust that it's actually doing anything until I find a good alternative. I'd say "Lookout" for this shoddy outfit and avoid any of their products.

After using this app's basic features for free for more than a decade and a half, when I tried to install it on my new phone today, the app popped up a subscription demand that can't be dodged. Reading through so many other reviews, I see this is by design. I guess it's paid only now, and it's time to find a new security app. Bye, Lookout. You were impressive while you lasted. I hope your paid subscribers are enough.

This is ridiculous. I opened the app, logged in and this ad popped up asking me to sign up for a free trail then have to play $59.99/yearly. I couldn't get past that screen. I even force closed the app and that screen still pops up. I'm not sure what hard times y'all are going through to force people to sign up and pay for y'all's service, but it sucks. I uninstalled the app. I would put in a request to delete my account, but I don't wanna sign up for a free trial & put a credit card down.
