    What are computer viruses and how can I prevent them?

    • Answer

    • Whether you're browsing the web, checking emails, or streaming your favourite shows, your computer is constantly interacting with the internet. But just like in the real world, there are digital threats lurking online—and one of the most common is the computer virus.

      This guide explains what computer viruses are, how they spread, and the simple steps TalkTalk customers can take to protect their devices and personal information.

      🧠What Is a Computer Virus?

      A computer virus is a type of malicious software (often called “malware”) designed to harm your device or steal your data. Once inside, it can slow performance, delete or corrupt files, steal personal information, or even hijack your device for criminal activity.

      🕵️‍♂️How Do Viruses Spread?

      Email attachments: Viruses often arrive disguised as invoices, photos or documents in your inbox.

      Malicious websites: Clicking unsafe links or pop-ups can trigger a hidden download.

      USB drives: Plugging in an infected stick can spread malware instantly.

      Free software or apps: Downloads from unofficial sites sometimes include hidden viruses.

      Trojan horses: Programs that look useful but secretly install malware when opened.

      🔍Spotting the Signs of a Virus

      Your computer runs much slower than usual.

      Programs crash or freeze unexpectedly.

      Strange pop-ups or ads appear.

      Files go missing or won’t open.

      Your browser redirects you to unfamiliar sites.

      You’re locked out of accounts or settings.

      🛡️How TalkTalk Helps You Stay Safe

      1. HomeSafe® – Network-Level Protection

      HomeSafe is a free web filter included with all TalkTalk broadband plans. It works at the network level, meaning it protects every device connected to your home Wi-Fi.

      Features include:

      Virus Alerts: Blocks websites known to contain malware

      KidSafe: Filters inappropriate content for children

      Scam Protection: Helps avoid phishing and fraud sites

      You can turn HomeSafe on or off and customise settings via your TalkTalk My Account.

      Note: HomeSafe can’t scan files you download or detect viruses hidden in email attachments. For that, you’ll need SuperSafe.

      2. SuperSafe Boost – Device-Level Protection

      SuperSafe is downloadable security software that protects individual devices, whether you're at home or on the go. It includes real-time virus scanning, safe browsing tools, banking and shopping protection, and parental controls. You can add SuperSafe Boost to your TalkTalk plan for up to 10 devices.

      🧰10 Steps to Prevent Computer Viruses

      1. Turn On HomeSafe: Log into your TalkTalk account and activate HomeSafe. Enable Virus Alerts and Scam Protection.
      2. Install Antivirus Software: Use SuperSafe Boost or another trusted antivirus tool for real-time scanning.
      3. Keep Software Updated: Always install updates for your operating system, browser and apps.
      4. Enable a Firewall: Make sure your device’s built-in firewall is turned on.
      5. Be Cautious with Email: Don’t open attachments or links from unknown senders.
      6. Avoid Dodgy Websites: Leave any page that looks suspicious or asks for personal info unexpectedly.
      7. Download Carefully: Only use official websites or app stores for software.
      8. Scan USB Drives: Always run a quick virus scan before opening files.
      9. Use Strong Passwords: Create long, unique passwords or use a password manager.
      10. Back Up Your Data: Regularly save important files to an external drive or cloud service.

      🧒Keeping Kids Safe Online

      Children are especially vulnerable to online threats. TalkTalk’s HomeSafe includes KidSafe filters to block inappropriate content, but here are extra tips:

      Set up parental controls on devices

      Use child-friendly browsers or apps

      Talk to your kids about online safety

      Monitor screen time and browsing habits

      For more advice, TalkTalk supports InternetMatters.org, a UK resource for keeping children safe online.

      🧑‍💻What If You Already Have a Virus?

      1. Disconnect from the internet to stop the virus spreading.
      2. Run a full scan using your antivirus software.
      3. Delete or quarantine any infected files.
      4. Change your passwords—especially for banking or email.
      5. Restore from a backup if needed.
      6. If the virus persists, contact a professional or TalkTalk support.
