Microsoft yesterday released an update to their free antivirus/antimalware/antispyware tool Microsoft Security Essentials:
KB Article: 975959
Microsoft Security Essentials is available in 32-bit and 64-bit versions for Windows 7 and Windows Vista, and in a 32-bit version for Windows XP.
Important: The download links for this updated program are located at the bottom of the page linked to above and are a little cryptic. Here's what you should download:
- Windows 7 32-bit: mssefullinstall-x86fre-en-us-vista-win7.exe
- Windows 7 64-bit : mssefullinstall-amd64fre-en-us-vista-win7.exe
- Windows Vista 32-bit: mssefullinstall-x86fre-en-us-vista-win7.exe
- Windows Vista 64-bit: mssefullinstall-amd64fre-en-us-vista-win7.exe
- Windows XP 32-bit: mssefullinstall-x86fre-en-us-xp.exe
Updates to this tool are always available via a notification from the program itself but you can also download the file manually from the link above.
Microsoft was unclear about the specifics involved in this Security Essentials update but chances are it involved minor bug fixes.
Microsoft Security Essentials is a free, fully functional antivirus program. If used properly, it should prevent infection from most viruses, spyware, and other malware threats.
Note: Do not run Security Essentials simultaneously with similar programs such as Norton AntiVirus, Avast, AVG, etc.; this program replaces those programs if you choose to do so. Running real-time antimalware tools at the same time will cause problems and will not provide you better protection.
