Who Needs an Antivirus Software?
Almost anyone who spends most of their time on the internet needs antivirus. Because where there’s Wi-Fi, there’s always a risk lurking.
It’s easy to think avoiding sketchy websites will keep you safe, but viruses can open the floodgates through everyday actions like checking your inbox or inserting a flash drive.
Since you can’t always tell what’s safe (after all, don’t judge a book by its cover), antivirus protection is non-negotiable. With countless programs available, we’ll guide you through the choices.
Threats That Antivirus Software Can Detect and Block
Viruses
A computer virus is formed when malicious code is embedded into a program or file, and it spreads by hitching a ride on things like email attachments, downloads, or infected USB drives.
Trojans
A trojan is malware that disguises itself as a safe-looking program, and it installs when someone is tricked into downloading or running it on their device.
Ransomware
Ransomware is malware that locks or encrypts your files and then demands a ransom payment to give you back access. Even if you pay, there’s no guarantee your files will actually be restored.
Worms
A worm is a self-replicating program that spreads through networks or devices without any user action.
Keyloggers
Keyloggers secretly record everything you type on your keyboard, including passwords, messages, and other sensitive information.
Rootkits
A rootkit is malware that hides itself to give attackers secret access, often using a collection of tools that grant them administrator-level control over a device.
Spyware
Spyware is malware that slips into your computer, quietly collects your personal data, and sends it to others without you knowing or agreeing to it.
Adware
Adware shows unwanted ads on your device, sometimes to support free apps, but it can also track your activity or expose you to other malware.
Ways Antivirus Keeps Your Computer Safe
Antivirus software helps keep your computer safe by finding, blocking, and removing harmful programs before they can cause problems. The best antivirus programs use several methods at once to give you stronger, all-around protection.
Key methods include:
Artificial Intelligence (AI)
AI-powered antivirus programs detect new and evolving threats by learning patterns of normal behavior, spotting unusual activity, and analyzing huge amounts of data to recognize suspicious files or actions.
Heuristic-Based Detection
Heuristics check how a file behaves and flag suspicious actions that might signal a virus, even if that virus hasn’t been identified before.
Behavior Monitoring
Behavior monitoring in antivirus software spots threats by watching what programs do in real time, instead of just checking them against a list of known viruses.
Sandboxing
Sandboxing is an antivirus feature that safely runs suspicious files in a controlled environment to see how they behave before letting them interact with your system.
Signature-Based Detection
Signature-based detection is the most traditional antivirus method, comparing files to a database of known malware signatures and blocking anything that matches.
Free vs. Paid Antivirus
When it comes to antivirus, the big debate is always free vs. paid and the truth is, both camps have their perks. Free antivirus is like a basic seatbelt: it covers the essentials, but you won’t get much beyond bare-bones protection.
Paid antivirus, on the other hand, is more like a full airbag system. It comes with extras like ransomware shields, phishing protection, parental controls, and even identity theft monitoring. As an expert’s view: free software can be enough if you’re a light user who sticks to trusted sites and keeps things updated, but if your work or data has real value (and let’s be honest, whose doesn’t?), the added layers of paid protection are worth the price of a few coffees a month.
Extra Features
The key features to look for in antivirus software depend on your specific needs:
Web Protection
Child Safety Settings
Gamer Security
Spam & Phishing Guard
from Emails
OS Compatibility
