Updated on September 22, 2026, by Xcitium
How Do Keyloggers Get Downloaded?
A keylogger is software or hardware that records keystrokes. Malicious keyloggers can reach computers through phishing attachments, fake software, malicious links, compromised websites, or other malware. Legitimate keystroke-monitoring tools also exist, but they should only be used on systems you own or administer with appropriate authorization and consent.
If you discover an unknown keylogger on your computer, treat it as a potential security incident.
A keylogger is a malicious application designed to record keystrokes. Sometimes, users download a keylogger inadvertently on their devices. In this article, we’ll discuss how to download keylogger onto your computer without your knowledge.
5 Common Ways Malicious Keyloggers Reach Computers
Malicious keyloggers commonly reach devices through:
- Phishing emails – Malicious attachments or links can deliver spyware.
- Fake software – Attackers may disguise malware as a legitimate application.
- Malicious websites – Compromised sites can expose users to malware downloads.
- Malicious links – Fraudulent links can direct users to infected files or websites.
- Exploitation of vulnerabilities – Unpatched software vulnerabilities may be abused to
How Do Keyloggers Get Downloaded?
Malicious keyloggers can reach a computer through several common attack methods.
| Method | How It Happens | Risk |
|---|---|---|
| Phishing emails | A malicious link or attachment delivers malware | High |
| Fake software | Malware is disguised as a legitimate application | High |
| Bundled downloads | A keylogger is hidden inside another installer | High |
| Compromised websites | A malicious or compromised site delivers malware | High |
| Fake updates | Users are tricked into installing a malicious update | High |
| Malicious browser extensions | A harmful extension captures user input | High |
| Existing malware | A Trojan or other malware installs keylogging functionality | High |
| Physical access | A hardware keylogger is connected to the device | High |
A user may therefore have a keylogger installed without intentionally downloading one.
HOW DOES A KEYLOGGER GET INTO THE COMPUTER?
There are numerous ways a keylogger can get inside your computer, and it’s important to know them so you can stay vigilant.
Method 1: Fake Emails
Fake emails are the number-one cause of malware infections worldwide. They conceal the keylogger behind deceptive attachments, tricking users into opening it by creating a sense of urgency. Once the user falls for this trick, they will inadvertently download a keylogger on their computer. That’s how to download keylogger through spear phishing, or fake emails.
Method 2: Fake Software
Fake software is also another leading cause of malware infections. These are applications disguised as legitimate ones and typically won’t be suspected as fake. The reason many users fall for this trick is that it hides the keylogger behind a seemingly harmless program.
It pops up on the screen while the user is browsing online. Often, the application it is disguised as is related to the user’s online searches, to lure them in more easily.
Fake software can be difficult to detect. If there’s no anti malware software installed on the computer, you may need to use a third scanner to detect and block it. That’s how to download keylogger through fake software.
Method 3: Phishing URLs
Phishing URLs are deceptive links that lurk on different websites. They can also be found on legitimate websites. Phishing URLs make false promises. They redirect users to malicious websites but never provide a free download of the software.
Phishing URLs may also generate a fake login page to steal usernames and passwords. The information entered is transmitted to the hacker via a remote server.
Method 4: Malvertising
Malvertising is short for malicious advertisement. It is an ad that installs malware in the background. Hackers that know how to install a keylogger sometimes make ads designed to install one when users close the ads. It can also redirect users to websites run by hackers to generate revenue.
A malicious ad is difficult to detect, but the malware it installs silently in the background can be detected and blocked by anti malware software.
Method 5: Exploit Kits
Exploits are tools designed to inject malware like a keylogger through a system vulnerability. Hackers deploy exploit kits to scan devices and web browsers for unknown vulnerabilities.
Often, it exploits outdated software, weak passwords, and outdated plugins or add-ons. Once a vulnerability is discovered, a keylogger goes through the computer. That’s how to download keylogger through exploit kits.
Software Keylogger vs. Hardware Keylogger
There are two primary categories of keyloggers.
| Software Keylogger | Hardware Keylogger |
|---|---|
| Runs as software on a device | Uses a physical component |
| Can arrive through malicious downloads | Usually requires physical access |
| May operate in the background | May sit between a keyboard and computer |
| Security software may detect it | Antivirus may not detect the physical device |
| Can potentially transmit captured data remotely | May store or transmit captured input |
Both can expose sensitive information when used without authorization.
Is a Keylogger Malware?
A keylogger is not automatically malware, but malicious keylogging software is commonly classified as spyware or information-stealing malware.
The distinction depends largely on authorization and purpose.
Legitimate use
Authorized monitoring technology may be used for:
- IT troubleshooting
- Testing
- Security research
- Authorized system monitoring
- Accessibility or input analysis
Malicious use
Attackers may use keyloggers to steal:
- Login credentials
- Banking information
- Payment-card details
- Private communications
- Business information
- Other sensitive data
Secretly capturing another person’s credentials or private communications creates serious privacy and security risks.
How to Check a Computer for a Keylogger
If you suspect unauthorized keylogging:
- Disconnect the device from untrusted networks if compromise is suspected.
- Run an updated anti-malware scan.
- Perform a full system scan.
- Review installed applications.
- Check unfamiliar startup programs.
- Inspect browser extensions.
- Review security alerts and suspicious activity.
- Inspect the keyboard connection and USB ports for unfamiliar hardware.
- Remove or quarantine confirmed malicious software.
- Scan the computer again after remediation.
For business computers, report suspected keylogging to the IT or security team rather than attempting extensive remediation independently.
WAYS TO PREVENT A KEYLOGGER ATTACK
A keylogger is not something we want on our computer, so it is important to protect your device from this malicious software. Now that you know how to download keylogger, how can you prevent it from happening?
Keep Software Up to Date
As mentioned early on, a keylogger can get installed through exploit kits. It is essential to keep your computer up to date to prevent a keylogger from getting through system vulnerabilities. Installing software updates is an important component of cyber security because it fixes bugs, glitches, and vulnerabilities that hackers exploit.
Avoid Downloading Crack Software
Malware can easily pretend to be legitimate software. However, if you only download from trusted vendors and websites, you can prevent falling victim to fake software. Free applications are widespread on the Internet. Verify the publisher before you download and install any application.
Avoid Opening Suspicious Emails
We are already aware that spear phishing is the leading cause of malware infections. Not opening emails from anonymous senders will help prevent malware infections.
Here are the things to remember about spear phishing:
- It creates a sense of urgency by using threats or triggering curiosity.
- It is from an anonymous sender.
- It demands that you download the email attachment.
If you notice these in an email, just delete it — it’s spear phishing.
Install Anti Malware Software
This is, by far, the most important component of cybersecurity. A computer without anti malware software is like an unarmed soldier on a battlefield. The World Wide Web contains the most dangerous malware. They are lurking, waiting for a vulnerable device to invade.
The anti malware software will keep your computer safe from malware attacks. It monitors your computer against malware to identify it in no time. Just look for reputable anti malware software online.
Conclusion
Now you know how to download keylogger on accident. A keylogger is a stealthy software that can get installed on a computer without the user’s awareness. Knowing how hackers install malware on IoT devices will help prevent a keylogger infection. Also, remember that anti malware software is an essential tool to keep your data and computer safe from varieties of cyber threats.
