Fake virus alerts are very common on some parts of the web and most of us have encountered one at some time or another. At worst, a real risk to the security of our computers and our data.

The purpose of most fake virus alerts is to intimidate or scare you into clicking a link. The irony, of course, is that until you click the link, there is no virus on your computer. After you click it, there may be. They will warn you that your computer has a virus and that you need to click a link and download software to get rid of it.

Unless you have antivirus software running on your computer, every virus alert you see is fake. If you do have AV software running, the only real alerts will be in a window displayed by your software.

Web page or browser tab pop-ups are always fake. Ignore it and close the window or browser tab. Consider whether you want to continue using a website that displays such warnings. These fake virus alerts are often adverts, paid for by cybercriminals who want you to download their malware onto your computer.

Any site that hosts such adverts is putting you and your computer at risk. Then re-open it without reloading all the tabs that were open in the previous session. If there are, bring them to the front and close them. But do take steps to check your Mac or PC for malware.

If you have an antivirus tool installed, use that to scan your computer. The virus scanner will quarantine any malware it finds and then allow you to remove it from your system.

This includes rootkits, worms, spyware, and other threats that often run undetected. Remember: Run the entirety of the virus scan. The full scan can take anywhere between 1—4 hours. A good idea is to schedule the scan at night. Then, you can leave your PC until the following morning, when the scan will be completed. When your antivirus finishes scanning, a notification will appear showing the results.

All malware on your system will be identified and quarantined. If this is the case, you can skip ahead to keeping your device protected. However, if your antivirus found malware on your system, you should go through the infected file list and hit the delete button on every compromised file. This preventative step ensures all traces of malware are removed. Many antiviruses such as Norton remember which files they previously scanned. This means they can analyze your disk much faster on a second full disk scan.

However, like on your first scan, let your antivirus completely finish its second scan. Once the scan is finished, the infected file list should be empty. However, if any compromised files do appear, review them as before and delete them as necessary.

Once this is done, your computer is malware-free. With all this in mind, you might be wondering how to keep your devices and personal information safe. Luckily, there are several steps you can take. You must keep your operating system OS , software, and drivers updated.

Hackers have been known to frequently take advantage of software vulnerabilities to gain access to your PC. The majority of the time, developers release software updates with security patches. These security patches fix vulnerabilities that hackers have previously exploited.

To keep your software updated at all times, you can download a comprehensive antivirus suite such as Avira that includes a vulnerability scanner. Most operating systems and applications have an auto-update option, too.

Always make sure auto-update is on so your computer can automatically keep all of your system drivers and devices updated.
