Windows Defender Reviews

Best firewall software of 2024
Known as Windows Defender since the release of Windows 10, the firewall is part of a suite of security tools included by default with Windows installations. Microsoft recommends that you leave the Defender on, even if you’re also using another firewall.

The best antivirus software 2022: Free antivirus and paid options tested
Microsoft's built-in antivirus software is now a heavy hitter.

Kaspersky AntiVirus mentions (27)

  • Looking for actually good antivirus.
    Bitdefender and Kaspersky have excellent free offerings. Kaspersky is lightweight. Both updates tend to be seamless. There is no NGAV consumer AV offering in the sense that they don't need constant signature updates like SentinelOne. However, with both solutions I have mentioned I have not seen updates cause crashing. Unless your PC has a hardware issue. Source: 8 months ago

    Assuming you've downloaded the correct US software, found here, create a new Kaspersky account, with a different e-mail, install Kaspersky Free, and try activation again. Source: 9 months ago
  • My friend's PC has been hacked/infected
    Download a free AV solution that is known to be effective, Bitdefender or Kaspersky. Source: 9 months ago
