How to Tell if Your Computer Has a Virus

If you think your computer has been infected, start by running a full system scan using your antivirus software and an anti-malware program. Review the threats and take any action that you can . If you are unable to delete the virus or infected files from your software, try restoring your computer to an earlier back-up before you began having problems.

Another strategy to try is deleting all of the temporary files on your computer. The method of clearing those files differs between systems but these processes are easy enough to research and implement for the average user. If your computer is malfunctioning and preventing you from accessing files to delete, you can try booting up in safe mode.

    Does Windows 10 Come With Antivirus Software

    It does indeed: Windows Defender. Windows has had virus protection for a number of years, and the latest iteration found in Windows 10 is the strongest its ever been.

    If your laptop or PC didn’t come with any other antivirus software pre-installed then Windows Defender will already be protecting your system.

    Given that Defender’s protection;is just as good as the best antivirus software, you can relax in the knowledge it’s keeping your laptops and PCs safe. In AV-Test’s most recent report covering July and August 2020, Defender stopped 100% of ‘known’ viruses and also 100% of zero-day attacks.;

    Microsofts offering should also have the advantage of being baked into the OS, but in fact it has a higher drag factor when it comes to system resources, causing apps to load more slowly than if you ran a paid-for security product such as Norton 360 Deluxe.

    Of course, it still has advantages: it doesn’t cost anything and you don’t have to install it or configure it in the first place, which is also a bonus.

    To check if Windows Defender is working correctly, launch the Windows Security app which will show you the status of antivirus and firewall.
