Understanding the Threats:

Before diving into protection methods, let's define some common terms:

Virus: A type of malware that replicates itself and spreads to other files and programs. Viruses often require user interaction, like opening an infected file, to activate.
Malware: A broad term encompassing any software designed to harm a computer system. This includes viruses, worms, Trojans, spyware, and ransomware.
Worm: Similar to a virus, but worms can self-replicate and spread across networks without user intervention.
Trojan Horse: Disguised as legitimate software, Trojans trick users into installing them. Once installed, they can perform malicious activities in the background.
Spyware: Secretly monitors your online activity and collects sensitive information like passwords and credit card details.
Ransomware: Encrypts your files and demands a ransom payment to restore access.

Prevention is Key:

The most effective way to protect your computer is through proactive prevention. Here are some essential steps:

Install and Maintain Antivirus Software: A reputable antivirus program is your first line of defense. Choose a well-regarded provider and ensure it's always up-to-date. Regularly scan your system for threats. Consider a premium option that offers real-time protection. Many also provide phishing protection.
Keep Your Software Updated: Software updates often include security patches that fix vulnerabilities exploited by malware. Enable automatic updates for your operating system, web browser, and other applications. Ignoring updates is like leaving your front door unlocked.
Be Careful with Email Attachments and Links: Exercise extreme caution when opening email attachments or clicking on links, especially from unknown senders. Verify the sender's identity before interacting with any suspicious content. Phishing attempts often masquerade as legitimate communications.
Use a Firewall: A firewall acts as a barrier between your computer and the internet, blocking unauthorized access. Most operating systems include a built-in firewall, but you can also use a dedicated hardware firewall for added security.
Practice Safe Browsing Habits: Avoid visiting websites with a poor reputation or those known to distribute malware. Look for the "https" in the address bar, indicating a secure connection. Be wary of suspicious pop-up ads or prompts to download software.
Use Strong Passwords and Enable Two-Factor Authentication: Strong, unique passwords are essential for protecting your accounts. Avoid using the same password for multiple accounts. Enable two-factor authentication (2FA) whenever possible for an extra layer of security. Consider using a password manager to securely store and generate complex passwords.
Backup Your Data Regularly: Regularly back up your important files to an external hard drive, cloud storage, or another secure location. This ensures that you can recover your data even if your computer is infected with ransomware or experiences a hardware failure. Having a recent backup can save you from needing drastic measures such as Computer Repair to recover lost data.
Limit User Privileges: Configure your user account with limited privileges to prevent malware from making significant system changes. Use an administrator account only when necessary.
Be Wary of Free Software and Downloads: Download software only from trusted sources, such as the official website of the developer. Be cautious of bundled software or offers to install additional programs during the installation process.
Educate Yourself: Stay informed about the latest cybersecurity threats and best practices. Understanding how malware works and how to avoid it is the best defense.

What to Do If You Suspect Infection:

If you notice unusual behavior on your computer, such as slow performance, frequent crashes, or unexpected pop-up ads, it may be infected with malware. Here's what to do:

Disconnect from the Internet: This prevents the malware from spreading to other devices on your network and limits its ability to communicate with command-and-control servers.
Run a Full System Scan with Your Antivirus Software: Use your antivirus program to perform a thorough scan of your entire system. Follow the program's instructions to remove any detected threats.
Use a Malware Removal Tool: Consider using a dedicated malware removal tool, such as Malwarebytes, to detect and remove any persistent or difficult-to-remove malware.
Change Your Passwords: After removing the malware, change all your important passwords, including email, banking, and social media accounts.
Monitor Your Accounts: Keep a close eye on your financial accounts and credit reports for any signs of fraudulent activity.
Consider a System Reset (as a last resort): If all else fails, you may need to reset your computer to its factory settings. This will erase all data on your hard drive, so make sure you have a recent backup before proceeding. This is often a service offered by Computer Repair professionals.

Sometimes, even with the best preventative measures, a computer can become severely infected or damaged. In these situations, it is often best to seek professional help. Need a Computer Repair professional? We've got you covered.
