How to Tell If a Keylogger Is Recording What You Type

Are you worried someone might be secretly recording everything you type? These hidden programs, called "keyloggers", can be tricky to spot. But don't fret – we're here to help you figure out if your computer or phone might be compromised.

What Exactly Is a Keylogger?

A keylogger is a type of software or hardware that records every keystroke you make on a keyboard. Think of it like a secret diary for everything you type, from your search queries to your passwords and private messages. This information can then be sent to someone else without you knowing.

Common Signs Your Device Might Be Compromised

While keyloggers are designed to be sneaky, they sometimes leave a trail. Keep an eye out for unusual behaviour from your device, as these can be red flags that something isn't right behind the scenes.

• Your device is much slower than usual, especially when typing or opening applications.
• Unexpected pop-up windows appear, even when you're not browsing the internet.
• Your web browser behaves strangely, like redirecting you to unfamiliar websites.
• There are new toolbars or icons in your browser that you don't remember installing.
• Your mouse or cursor seems to move on its own, or clicks things without your input.

Check Your Running Programs and Apps

Sometimes, a keylogger might show up in your list of active programs, even if it's disguised. It's a good idea to regularly check what's running on your computer or phone.

• **On Windows:** Press `Ctrl + Shift + Esc` to open Task Manager. Look for unfamiliar programs under the 'Processes' tab.
• **On Mac:** Open 'Activity Monitor' from Applications > Utilities. Check the 'CPU' and 'Memory' tabs for suspicious applications.
• **On Android:** Go to `Settings > Apps` or `Apps & notifications`. Review the list for any apps you don't recognise or remember installing.
• **On iPhone:** While iPhones are generally more secure against keyloggers, regularly review your installed apps and their permissions under `Settings`.

Scan with Reputable Anti-Malware Software

One of the most effective ways to detect and remove keyloggers is to use good quality anti-malware software. These programs are designed to hunt down and neutralise malicious software.

• Install a well-known and reputable anti-malware program (e.g., Avast, AVG, Malwarebytes, Bitdefender).
• Run a full system scan. This might take some time, but it's thorough.
• Review the scan results carefully and remove any detected threats.
• Keep your anti-malware software updated and schedule regular scans.

Review Your Browser Extensions and Add-ons

Keyloggers can sometimes hide within browser extensions. These little programs add extra features to your web browser, but rogue ones can record your activity.

• **In Chrome:** Click the three dots in the top right > `More tools > Extensions`.
• **In Firefox:** Click the three lines in the top right > `Add-ons and themes > Extensions`.
• **In Edge:** Click the three dots in the top right > `Extensions`.
• Carefully review each extension. If you don't recognise it, don't use it, or it seems suspicious, disable or remove it.

Key takeaway

Identifying a keylogger can be challenging, but by being observant and using the right tools, you can protect your privacy. If you suspect your device is compromised, remember to use a clean device to change your important passwords and then focus on cleaning your affected device. Staying vigilant is your best defence!
