Is Your Computer Infected? Here’s How to Tell
In today’s digital age, our computers are central to everything we do—work, banking, shopping, and entertainment. So when something goes wrong, it’s not just inconvenient—it can be downright disruptive.
At RepairTech, we often get asked: “How do I know if my computer has a virus or malware?” If your machine is acting strange, it could be more than just a software hiccup.
Let’s break it down.
🐴 What Is a Trojan Horse?
A Trojan Horse is one of the most common threats to computers—especially those running Microsoft® Windows™. Trojans disguise themselves as legitimate software (like free games or apps), but once installed, they wreak havoc:
Changing system settings (like your desktop background)
Disabling critical features (like the control panel)
Creating backdoors for hackers to steal sensitive data (like passwords and credit card numbers)
Trojans don’t replicate, but they can quietly give someone remote access to your system. Nasty stuff.
💻 What Is Malware?
Malware is the umbrella term for malicious software, and it comes in many ugly forms:
Ransomware – Locks your files and demands payment
Spyware – Tracks your activity and personal data
Adware – Bombards you with endless pop-ups
Scareware – Tries to frighten you into installing fake software
Fake Antivirus (Fake AV) – Pretends to protect you but actually infects your system
You might’ve seen these bundled with "free" downloads—browser toolbars, PC cleaners, or bonus apps you didn’t ask for. We techs call this CrapWare, and sadly, it’s often added by even legitimate software distributors.
🦠 What Is a Computer Virus?
The term "virus" is often misused, but in technical terms, a virus is a program that replicates itself and spreads to other devices.
Back in the floppy disk days, viruses spread like wildfire. Today, true viruses are less common (thanks to better security), but they still exist—especially embedded in executable files or disk boot records. If left unchecked, they can damage files, crash systems, and slow down performance.
🔍 Common Signs Your Computer May Be Infected
Watch out for these red flags:
Clicking on a search result takes you to a suspicious or irrelevant website
Frequent pop-up ads—even when you’re not browsing
Your computer suddenly becomes very slow
Your email account sends messages you didn’t write
You see toolbars or apps you didn’t install
A strange antivirus program appears out of nowhere
You get calls from “Microsoft” or an antivirus company wanting remote access (always a scam!)
You’re locked out of your system and asked to pay a ransom
A black command prompt box (COMMAND.EXE) keeps flashing
Your antivirus software is disabled or crashes unexpectedly
🛡️ How to Protect Yourself
Keep your antivirus software up to date (yes, even if you're on a Mac)
Don’t install programs from untrusted sources
Decline "bonus offers" during software installations
Avoid clicking suspicious links in emails or pop-ups
Back up your important files regularly
