Protecting your computer from viruses and malware is key to keeping your data safe and your computer running. Threats are always changing, so you need to be proactive. Here’s how to do it.
Understanding Viruses and Malware
Before we get started, let’s define viruses and malware and how they can affect your computer.
What are Viruses?
A virus is a type of malicious software that attaches itself to legitimate programs or files. When these programs are run, the virus can spread to other files, corrupt data, steal information, or cause harm to your computer. Viruses are spread through infected email attachments, downloads from shady websites or even USB drives.
What is Malware?
Malware is a broader term that includes viruses but also other types of harmful software like ransomware, spyware, adware and trojans. Each type of malware has its own way of infecting your computer and causing damage, from stealing your sensitive information to locking you out of your system entirely.

How to Protect Your Computer
There are several steps you can take to stop viruses and malware. These are a combination of prevention and regular maintenance to keep your system safe.
1. Install and Update Antivirus Software
Antivirus software is your first defense against viruses and malware. This software detects and removes malicious software before it can do harm.
- Choose Good Software: Select an antivirus program that’s known for being comprehensive.
- Keep It Up to Date: Update your antivirus software regularly to stay protected against the latest threats.
Most antivirus software has automatic updates, which should be enabled to stay protected.
2. Enable a Firewall
A firewall is a barrier between your computer and the internet. It monitors incoming and outgoing traffic and blocks suspicious activity.
- Use Built-in Firewalls: Most operating systems (Windows and macOS) have built-in firewalls. Make sure they are enabled and configured correctly.
- Consider a Hardware Firewall: For extra protection especially in a business environment a hardware firewall can add an extra layer of security.
3. Update Your Operating System and Software
Software developers release updates to fix security holes in their products. Keeping your operating system and applications up to date is key to being secure.
- Enable Auto Updates: Let your operating system and essential software update automatically. This way, you’ll always have the latest security patches.
- Manually Check for Updates: Occasionally check for updates to make sure nothing is missed especially for critical software like your web browser and email client.
4. Be Careful with Email Attachments and Links
Email is a common way for viruses and malware to spread. Being careful what you open and click on can prevent many infections.
- Don’t Open Unsolicited Attachments: Don’t open email attachments from unknown senders, as they could contain malicious software.
- Hover Before You Click: Hover over links to see the actual URL before you click. If it looks suspicious or doesn’t match the sender’s domain, don’t click it.
5. Use Strong Passwords and 2FA
Passwords are your first line of defense for your accounts and data. Using strong, unique passwords and 2FA can make a big difference.
- Create Strong Passwords: Use a mix of letters, numbers and special characters in your passwords. Don’t use easily guessable information like birthdays or common words.
- Enable 2FA: Whenever possible, enable 2FA. This adds an extra layer of security by requiring a second form of verification, like a code sent to your phone, in addition to your password.
6. Back-Up Your Data
Even with all the precautions, no system is 100% immune to attacks. Backups ensure you can recover your data if your computer gets compromised.
- External Drives or Cloud Services: Back up your important files to an external drive or a secure cloud service.
- Automate Backups: Set up automatic backups so your data is always protected without having to remember to do it manually.
7. Don’t Download from Untrusted Sources
One of the easiest way for malware to get into your system is through downloading files or programs from untrusted sources.
- Download from Reputable Sites: Download software from reputable websites or official app stores.
- Be Careful with Free Software: Free downloads can come with unwanted extras like adware or spyware.
Always read the terms and conditions and opt out of any additional software installations.
8. Know Phishing Scams
Phishing scams trick you into providing personal information like passwords or credit card numbers by pretending to be a legitimate entity.
- Learn to Recognize Phishing: Phishing emails often look legitimate but have subtle errors like misspellings, poor grammar or incorrect URLs.
- Use Anti-Phishing Tools: Many antivirus programs and web browsers have tools that can detect and block phishing attempts. Enable these features for extra protection.
What to Do If Your Computer Is Infected
Even with all the precautions, infections can still happen. Knowing what to do if your computer is infected is key to minimizing the damage.
1. Disconnect from the Internet
If you think your computer is infected, disconnect it from the internet immediately. This will prevent the malware from spreading to other devices or sending data back to the attacker.
2. Run a Full Scan
Perform a comprehensive scan with your antivirus software to identify and remove any malicious software.
3. Restore from Backup
If the infection has caused a lot of damage, you may need to restore from backup. This will wipe the infected system and replace it with a clean copy of your data.
4. Get Professional Help
If the problem persists or you’re not sure what to do, get professional help. A computer technician can remove stubborn malware and get your system back to normal.
