All About Malware – Types, Threats, and How to Protect Your Devices

OVERVIEW:

In this blog, we explore the basics of malware: how to identify it, what signs to look out for, and how to handle a suspected infection. From unwanted pop-ups to redirected browsers, malware can present itself in a variety of sneaky ways. James from Tech walks us through some of the most frequently asked questions, as well as steps you can take to diagnose and remove potential malware. He also emphasizes why some methods should be avoided and highlights tools like Malwarebytes and Windows Defender. This guide is a valuable resource for anyone unsure if their system has been compromised.

REPAIR TIME & SKILL LEVEL:

This repair is estimated to take about 2–3 HOURS to complete and is of INTERMEDIATE difficulty, requiring familiarity with system settings, cautious software management, and comfort using antivirus tools.

STEPS:

Tools You Need

For this malware removal walkthrough, you will need access to your computer’s Task Manager, system settings like “Add or Remove Programs,” and malware scanning software such as Malwarebytes and Windows Defender. You’ll also use built-in search tools and should be able to safely navigate lists of installed programs.

Identify suspicious behavior on your system

Notice strange activities such as fans spinning loudly, files disappearing, pop-ups, or redirected websites — all are possible signs of malware.
Unexpected operating system behaviors like high CPU usage or programs opening on their own can indicate infection.
Use these symptoms as your initial trigger to start investigating further.

Understand if you’re at risk after a download

If you downloaded a suspicious file but didn’t run it, you’re likely safe.
Simply clicking a file without allowing it to run, especially if you get a warning and choose not to proceed, usually doesn’t cause infection.
Malware typically needs to be executed to begin operating on your system.

Use antivirus and antimalware programs

Real-time protection should already be scanning new files and devices connected to your system.
For deeper detection, run a full system scan using trusted programs like Malwarebytes or Windows Defender.
These programs are designed to detect and remove known malicious software from your system.

Detect malware using system resource usage

Press Ctrl + Alt + Delete and open the Task Manager to check system usage.
Look at your CPU, memory, disk, and network usage — values locked at 99–100% may indicate malware.
Sophisticated malware might hide resource usage when you open Task Manager, so unusually high usage when idle could still be a red flag.

Manually review installed programs

Open the Start Menu and search “Add or Remove Programs.”
Go through the list to look for suspicious or unfamiliar software.
Watch out for common adware names like “Free YouTube Toolbar,” “Gadget Box,” or “FunMoods Toolbar” — these often disguise themselves with generic names.

Use online references to confirm suspicions

If you see a program you don’t recognize, Google the name or visit trusted resources to see if others report it as malware.
For example, terms like “Xfinity Search” may pretend to be from Comcast but could be malware.

Avoid manual file searching

Don’t attempt to locate malware manually in system folders like System32.
Browsing the file tree or ending random processes in Task Manager can lead to accidental deletion of critical system files.
This can break your operating system, cause boot failures, or lead to data loss.

Don’t overload your system with antivirus programs

Installing too many antivirus programs doesn’t improve detection and may cause conflicts.
Most antivirus tools use similar detection methods and databases.
Stick with trusted tools like Malwarebytes and Windows Defender for optimal performance.

Use VirusTotal wisely

VirusTotal allows you to upload suspicious files and scans them with multiple engines.
Only upload individual files you suspect, not entire folders or system libraries.
Even advanced technicians avoid manually battling malware without proper tools.

When to consider a clean install

If multiple scans and removal attempts fail, consider reinstalling Windows as a last resort.
A clean install can eliminate nearly all types of malware.
Backup important files beforehand, and seek help if needed.
