I already have described about Microsoft Security Essentials anti-virus, a better anti-malware for your windows system. Every Antivirus should be regularly updated to know the latest virus definitions. So your antivirus will able to detect the latest malwares/viruses/trojans/spyware if the individual definition is included. So like other anti-viruses, you need to update your MSE(Microsoft security essential) too. But the problem is normally we need to update it from the program. But every one don’t like this process. Many guys like me don’t like automatic update. So if we want to manually/separately download the virus definition file, how can we do it? So that, we will able to backup the definition.
Download MSE Virus Definition File Manually:
Microsoft provides us opportunity to download it’s MSE’s malware definition database directly. It can be found here.
