Do Antiviruses Remove Existing Viruses in 2024? (Quick Guide)

Reading time: 10 min

Antiviruses can remove existing viruses just as they can protect you from getting infected in the first place. They are designed to allow you to run a full scan of your system and remove any virus if found.

While every antivirus software does have a virus scanning feature, it’s the ability to perfectly remove all viruses, including the evasive ones that really matters. I’ve seen antiviruses that can only remove 50% of viruses or malware, but the best ones can get rid of 100% of malware and keep you protected from emerging virus threats.

I tested over a dozen antivirus options and found the best ones for removing existing viruses. Norton removes 100% of viruses and malware, including those discovered in the last 24 hours. You can try Norton risk-free using the 60-day money-back guarantee.

Signs of Virus Infection

Detecting a potential virus infection early is crucial to protect your digital life. A top antivirus gives you complete peace of mind, but if you don’t use one, you may be infected without realizing it. Some signs that could mean your device is infected with viruses or malware are these:

  • Sluggish performance — noticeably slow system speed, frequent freezes, or unresponsive applications.
  • Excessive pop-ups — unexpected pop-up ads, even when not browsing the internet.
  • Unusual activity — programs launching on their own, files and folders disappearing, or unauthorized changes to settings.
  • Increased data usage — a sudden spike in data usage without any apparent reason, indicating hidden background activity.
  • Disabled security software — inexplicable deactivation or interference with your antivirus or firewall protection.
  • Unwanted browser changes — homepage, search engine, or toolbar modifications without your consent.
  • Missing files or icons — files disappearing or being moved without your knowledge.
  • Strange system behavior — unusual system crashes, error messages, or new, unfamiliar icons appearing on your desktop.
  • Unexpected emails or messages — friends receiving strange messages or links from your email or social media accounts.
  • High network activity — unexplained network traffic, indicating potential malware communication.

Attempting to use your default antivirus protection like Microsoft Defender might leave your system still exposed. While Microsoft Defender has improved considerably over the years, it still can’t match the protection levels of top-tier antiviruses like Norton and TotalAV.

Quick Guide: How to Remove Existing Viruses

  1. Install a top antivirus software. I recommend you sign up for Norton antivirus, download the setup, and install it on your device.
  2. Run a full virus scan. Once you’ve successfully installed the antivirus software, run a full device scan to detect any virus or malware on your system.
  3. Remove all detected viruses. If a virus or malware is detected, you can quarantine it or remove it from your device with the antivirus program.

Step-By-Step Guide: How to Eliminate Existing Viruses From Your Device

Step 1: Install a Good Antivirus Software

Begin by downloading and installing a trusted antivirus program suited for your device. Look for well-established options like Norton antivirus that offers perfect malware removal scores and provides frequent updates to keep up with evolving threats.

Norton is the best antivirus for removing all existing viruses, thanks to its 100% malware detection rates, excellent range of features, and ease of use.

Step 2: Scan Your Computer

Once installed, initiate a full system scan using the antivirus software. This scan will meticulously search your device’s files, folders, and applications for any traces of malware or viruses.

Norton’s virus scanner is pretty fast — a full system scan takes around 20 minutes for a comprehensive analysis of your entire device.

Step 3: Reboot Your Device

After the initial scan, restart your device. This step is crucial as it can help neutralize certain types of viruses that are active during startup. Once you reboot your device, you’re preventing these viruses from continuing their harmful actions.

Step 4: Scan Again

Once your device restarts, run another full system scan using the antivirus software. Some viruses may be deeply embedded in your system and might only become detectable after a reboot. Repeat this scan-reboot-scan process until the antivirus reports no more infected files.

Step 5: Keep Your Protection Active

After successfully removing the viruses, ensure your antivirus software remains up to date. Regularly schedule automatic scans, ideally on a weekly basis, to proactively catch any new threats that might try to infiltrate your system.

Also, use a virtual private network (VPN) when browsing, so your entire internet traffic is encrypted, thus protecting you against cyber threats, hackers, and malicious downloads.
