The next best way to protect yourself from malware is to refrain from downloading any unknown files and avoid strange links altogether.

Phishing attacks are getting more sophisticated, but be skeptical of anyone—even contacts you know—telling you to download attachments or click links out of the blue. Some software can still monitor your on-screen interactions, however, so this should be seen as a supplemental tool and not a complete solution. Look for antivirus software that includes anti-spyware and anti-keylogger protection. As with all forms of viruses, new, more sophisticated keystroke malware is being written all the time, so be sure to keep your software up to date to stay secure.

Similar to a virtual keyboard, voice-to-text conversion software can circumvent forms of keylogging that specifically target your physical keyboard. Keystroke monitors thrive on stealth, but can a keylogger be detected? Keylogging malware may show many common virus warning signs , including slower computer performance when browsing or starting programs, abnormal delays in activity, pop-ups, new icons on your desktop or system tray, or excessive hard drive or network activity.

If you detect any of these, you may want to follow the steps below to identify and remove keylogging malware. Successful keystroke logger detection starts with taking stock of the programs and processes running on your computer.

While many of these may have unfamiliar or even suspicious-looking names, they may blend in with the names of other software.

A keylogger surveils what someone types on their keyboard, recording their interactions with browsers, word processors, webforms, and other text-based media.

Keyloggers are used to monitor how a user interacts with their keyboard as a means of recording their behavior, usage, or personal information. While keylogging tools are not illegal in and of themselves, they are often used in an illegal manner by cyberattackers, identity thieves, or other malicious users to surreptitiously steal information or track activity without user consent.

Early cases of keylogging in the s involved government surveillance of electronic typing machines. Today, keystroke monitoring software is widely available for commercial and personal use. Mobile devices can be monitored using keylogging applications.

Some of these programs may be able to monitor screen interactions, downloads, location data, and even conversations. Keyloggers may be difficult to detect, but they are identifiable. If your device has been infected by keylogger malware, you may notice system lag, noticeable overheating, or the presence of unfamiliar software, system processes, or browser extensions. One of the best ways to protect yourself from keyloggers is to refrain from downloading files or clicking links from suspicious emails, messages, or contacts.

Enabling two-factor authentication is also helpful in preventing identity theft that may result from malicious keylogging. If you detect a strange program that may be a keylogger in your browser extensions, system processes, or software list, remove it immediately.

Browser extensions can be easily removed from your list of extensions, and device applications can be deleted, moved to the trash, or uninstalled. All rights reserved.

Trojan viruses, as in the the narrative, seem benign but contain malicious content. Trojans are applications that appear to serve some useful function -- a number of these infections, for example, masquerade as anti-virus software -- but include code that performs operations without the user's permission or even enables an attacker to gain remote access to a PC.

Trojan horses are divided into different groups depending on their method of abuse, but the most common and most dangerous are remote-access Trojans. Once a hacker gains access to an infected system via a RAT, the individual can steal confidential information, install additional malware to the computer, record and log keystrokes, damage the integrity of the hard drive, and countless other activities that can cost a business thousands of dollars to resolve.

Norton Antivirus detects and removes Trojan horses. Via LiveUpdate, administrators can download to a computer the latest virus definitions, which contain information that the scan engine needs to find existing and emerging threats on a system.

After bringing Norton Antivirus up-to-date, admins should perform a virus scan in Safe Mode to search for Trojans and other viruses.

The software allows users to quarantine, delete or restore the infected files it finds. The program can also repair files, but that's not an option for a Trojan horse, since the entire application contains malicious data. Norton Antivirus, like all antivirus software, cannot detect all malware on the Web.
