Windows Defender
Should you install third-party solutions at all if you have Microsoft Security Essentials? This is the standard antivirus included with Windows 10. If you are using earlier versions of Windows, you can download Security Essentials separately.
Dr.Web CureIt!
The Dr.Web CureIt! utility will cure an infected system once, but it is not designed to provide your PC with real-time protection from viruses. The utility available on our website always features the latest virus definitions, but its virus databases aren’t updated automatically. Included in Dr.Web CureIt! is a set of virus databases that are only current until a new update is released (usually one or more times per hour).
