Microsoft Security Intelligence Report v14: Why antivirus software matters

  • Comments 50

The latest volume of the Security Intelligence Report (SIR) highlights the importance of using antivirus software.

Antivirus software helps protect your computer from malicious software (malware) and can be downloaded or installed inexpensively or at no charge. Still, according to the SIR v14 findings, 24 percent of computers worldwide were not running up-to-date antivirus software, leaving them 5.5 times more likely to be infected with viruses.

Possible reasons why your computer may not be protected:

This new edition of the SIR compares infections on protected and unprotected computers, offering evidence as to how many people are not using up-to-date antivirus software and are thus facing increased risk.

If you don’t have antivirus software, Microsoft recommends that you download it now from Microsoft or from another trusted vendor. If you already have Windows 8, antivirus software is included with the operating system. You are not required to do anything to set it up. If you are using older versions of Windows, Microsoft provides a free antivirus software called Microsoft Security Essentials, which can be downloaded from our website. Many of our partners also offer antivirus software.

Data used in the SIR analysis includes (but is not limited to):

  • Threat intelligence from more than 1 billion systems in more than 100 countries and regions.
  • Microsoft Security Essentials—operating globally in more than 30 languages.
  • Malicious Software Removal Tool—downloaded and executed more than 1 billion times in the second half of 2012.
  • Billions of pages scanned by Bing each day.

Take action to help protect your computer and reduce the risk of becoming a victim to cybercrime:

  • I have micosoft security essentials. it showing i'm protected but i have a red shield  and that my anti-virus is switched off.

  • I been a victim yesterday for the second time in last of 2 month's to get a money pack with a code number , insert the code before my computer will be released back to me. Is this a new shake down by pirates to steal money from us. They use Homeland Security, DOJ and all that stuff to scare you and threaten you for criminal activity on your own computer. I am lost at what I need to do! Can anyone help? There are several Trojan viruses including Recycle virus. Any experts out here in cyber-land what I need to do? I have AVG for security and since then I have nothing but problems! Thank you

  • julie , I have the same problem

  • Homeland Security has blocked me from acces to my computer. It blocked the Start up Program

  • Some software seems to suggest that it might be necessary to disable your antivirus software ' [temporarily] . I am always nervous about this idea. Does Microsoft say anywhere on its XP software (I have windows XP) how, in detail, a person does this?
