What Is A Keylogger And How Does It Work?
A keylogger is a type of malware that secretly records every keystroke you make on your keyboard. This can include passwords, credit card numbers, and other sensitive information. Keyloggers can be installed on your device through phishing emails, infected software downloads, or exploited vulnerabilities.
Keyloggers work by running in the background of your device, capturing every keystroke and storing it in a log file. This file can then be transmitted to the attacker, who can use the stolen information for malicious purposes. Keyloggers can be especially dangerous because they often go undetected, even by antivirus software. This is why it’s essential to have robust security measures in place to detect and remove keyloggers.
What Are The Signs That My Device Has A Keylogger?
If your device has a keylogger, you may not notice anything out of the ordinary at first. However, there are some signs that could indicate the presence of a keylogger. For example, if you notice that your device is slow or unresponsive, or if you see unusual programs running in the background, it could be a sign of a keylogger.
Another sign of a keylogger is if you receive suspicious login alerts or notification of unfamiliar login attempts. You may also notice that your login credentials are being rejected, even though you’re certain you’re entering the correct information. If you suspect that your device has a keylogger, it’s essential to run a thorough scan with your antivirus software and change all your passwords immediately.
Can Avast Detect Keyloggers?
