Understanding The Malware

What is Malware?

Malware, short for malicious software, refers to various forms of harmful software designed to infiltrate, damage, or disable computers, computer systems, networks, or even steal personal information. It is a broad term that encompasses various harmful and intrusive software including viruses, worms, trojans, ransomware, spyware, and adware.

Different Types of Malware

• Viruses are self-replicating malware that spread by inserting copies of themselves into other computer programs or files.
• Worms are standalone malware that spread across networks without the need for a host program or human help.
• Trojan horse malware disguise themselves as legitimate software but upon installation, they can take control of your computer.
• Ransomware locks you out of your files and demands ransom to unlock them.
• Spyware stealthily monitors your computing activity and sends the data back to the malware originator.
• Adware serves unwanted ads and can also come with spyware capabilities to gather data about your surfing habits.

Malware Infection on Windows Systems

Malware usually finds its way onto a Windows system through the internet and emails, often disguised as a legitimate software download or a clickable link. Sometimes it comes bundled with free software from the internet or may spread via removable drives, such as USB drives.

For example, a virus can be attached to an email sent from an infected computer, be disguised within free-to-download music, a game, or a torrent file. The virus then replicates and inserts itself onto other systems every time the contaminated file is shared.

Trojans can trick users into loading and executing them on their systems. Often, the user is duped into believing that the Trojan is a useful piece of software.

Malware can also exploit security holes in a network to access a computer without the user’s knowledge. A worm, for example, can exploit security vulnerabilities to spread itself automatically to other computers through networks.

Potential Impact of Malware

The potential impact of malware on a Windows system varies extensively depending on the type of malware. Generally, it can slow down your system, corrupt or delete your files, change your system settings, or even control your computer. Financial and identity thefts are also common goals of malware. In some cases, an infected computer can be turned into a bot to spread malware or launch attacks on other systems or networks.

Interpreting Scan Results

After completing any of the above scans, Windows Defender will show you the results. If any malware has been detected, it will be shown under ‘Threats Found’. Clicking on this will provide more details about the detected malware.

Windows Defender will automatically take action on known threats, but may ask for your input for some detected threats. If needed, you can choose actions such as ‘Remove’, ‘Quarantine’, or ‘Allow’ on a per-case basis.

In most cases, ‘Remove’ or ‘Quarantine’ are the safe options. ‘Allow’ should only be used if you are sure the detected software is safe and has been marked as a threat incorrectly.

Furthermore, for ongoing protection, it’s important to ensure Windows Defender’s real-time protection is turned on. This feature will monitor your system continuously for potential threats.

Third-party anti-malware tools

Selection of Reliable Anti-Malware Tools

Select from various legitimate, reliable third-party anti-malware tools available in the market to help protect your Windows system. Tools such as Malwarebytes, Spyhunter, Norton, Combo Cleaner, and Bitdefender are among the most reputable ones, with robust malware detection and removal features. Spend some time researching the right tool for your specific needs and system configuration. Consumer reviews and cybersecurity forums can provide useful insights.

Downloading and Installing Anti-Malware Tools

The next step is downloading and installing your chosen anti-malware tool. Visit the software’s official website to ensure the authenticity of the software and avoid downloading from third-party websites to steer clear of potentially harmful freeware. Follow prompts to install it on your system. Make sure to update it frequently to benefit from the latest malware signatures and detection algorithms.

Performing a Full System Scan

Upon successful installation, it is time to run a scan on your system. This process allows the software to thoroughly check every file and program for potential malware.
