Microsoft Safety Scanner is a free, on-demand virus and malware scanning tool provided by Microsoft.
Here are some of the features of Microsoft Safety Scanner:
Malware Detection:
Microsoft Safety Scanner scans your computer for a wide range of malware, including viruses, spyware, adware, and other malicious software.
Quick and Full Scan:
It offers both quick scans for a rapid assessment and full scans for a more comprehensive analysis of your system.
Offline Use:
Safety Scanner is designed to be used offline, meaning you can download and run it without requiring an internet connection at the time of the scan.
Automatic Expiry:
To ensure you have the latest version of the tool, Microsoft Safety Scanner automatically expires after a specific period. You need to download a fresh copy for each use.
Removal of Threats:
Once the scan is complete, the tool helps you remove or quarantine any identified threats.
Complementary Tool:

Here are some of the pros of using Microsoft Safety Scanner:
Free:
Microsoft Safety Scanner is provided free of charge by Microsoft, allowing users to perform manual malware scans without purchasing additional software.
Portable:
It's a portable tool, meaning you can carry it on a USB drive and use it on different computers without installation.

The tool can detect a variety of malware types, helping to ensure a comprehensive scan and potential threat removal.
No Conflicts:
Since it doesn't provide real-time protection, there are no conflicts with existing antivirus software.
Overall, Microsoft Safety Scanner is a good option for users who want a free, portable malware scanner that can be used to check for malware that their antivirus program may have missed.
