How to Fix Facebook Let’s Check Your Device for Malicious Software False Alarm

Written by

Just tonight, My Facebook account was locked by Facebook and it says my computer was infected with malware, even though I know it is not infected – because I just reformatted my computer a few weeks ago. And Why on Earth they know that my computer is infected with a virus, do they install something to my computer? a tracking program or something? that’s impossible because a website cannot access your device unless you install something from them! If that something to do with my account, they must provide some options to disable apps that doing something to my account and not to force anyone to install their sponsored Anti Virus program.

Other browser like Microsoft Edge and Mozilla Firefox has no problem and I can still use Facebook without those alert. Only in my primary browser Google Chrome, when you tried to login your account this message keeps popping up:

And when you press the Clean This Device, another step will appear saying all about the Malicious Software.

Then the next step is they want you to download the program and install their ESET Antivirus program.

Then they will instruct you how to install their Anti-Virus.

Well, I didn’t follow those step and did not install their program, because I don’t feel comfortable installing it and it may destroy some of my files.

Everytime, I login back to my Facebook this error message keeps appearing. I even tried uninstalling Google Chrome and reinstalling it, also tried using the Beta version but that doesn’t work as well. Until I found a solution that works and remove this False Positive virus alarm of Facebook.

Hi Erwin, we’re continuously working to keep your account secure. We’ve noticed that this device may be infected with malicious software. To continue to use Facebook, you can either use other devices or clean this device by downloading the scanner provided by Facebook and ESET.

About Malicious Software

Malicious software tries to steal personal information and often spread spam on Facebook through links or downloads.

How did malicious software get on my computer?

Malicious software can be spread through links or downloads, so it’s important to never click on a link, install software or follow instructions from sources you don’t know.

Why should I clean malicious software?

If you have malicious software, your account might display unusual behavior such as sending many messages, liking many Pages and sending friend requests to people you don’t know personally. You might also notice slow processing, computer crashes or suspicious browser extensions.

How can I keep my account secure?

Watch out for fake Pages and apps/games. Be suspecious of Pages promoting offers that are too good to be true.

Don’t accept friend requests from people you don’t know. Sometimes scammers will create fake accounts to friend people.

Never give out your login info (ex: email address and password). Sometimes people or Pages will promise you something (ex. free poker chips) if you share your login info with them.
