Microsoft Security Scanner

 

Introduction

  • The Microsoft Safety Scanner is a free stand-alone virus scanner that is used to remove malware or potentially unwanted software from a system. The tool is easy to use and packaged with the latest signatures, updated multiple times daily.
  • The application is not designed to replace your existing antimalware software, but rather act as an on demand virus removal tool in situations where you suspect your real time antimalware software might not be working correctly.
  • If the antimalware program you are running regularly becomes disabled without your knowledge you may have malware or rogue security software on your system. Running the Microsoft Safety Scanner can help detect and remove malware or potentially unwanted software that may be disabling your real time antimalware software.
  • This is especially useful when your access to security websites is blocked by malware on the infected machine.

Installation Guide

  • Installing the Microsoft Safety Scanner does not require you to uninstall your existing antimalware software.
  • The program can be started right after downloading or transferring it to a PC. The tool is approximately 70 megabytes in size and includes all the latest definition/signature files provided by the Microsoft Malware Protection Center.
  • Upon downloading the tool, users are prompted with three different scan options:
    • quick scan: scan the memory, registry and areas on the system most likely to have malicious code like viruses, spyware or computer worms.
    • full scan: includes all the items scanned in a quick scan plus a scan of all your files in your fixed drives.
    • customized Scan: A customized scan runs a quick scan and includes any additional files specified.

  • While it is not a replacement for a full antimalware solution with real-time protection, the Microsoft Safety Scanner does offer detection and cleaning using the same set of signatures and technology utilized by Microsoft Security Essentials. It is important to note that because the Microsoft Safety Scanner is a stand-alone tool, the signatures will expire ten (10) days after downloading. After the 10 day period has expired, we recommend downloading a new version of the tool in order to get the latest anti-malware definitions.
  • If you think your system has been infected with malware but your real time antimalware software isn’t detecting anything, we suggest http://127.0.0.1:5723/lib/images/wrap.gifdownloading and running the Microsoft Safety Scanner.
