Do I need to update Windows Defender Offline?

Question : Do I need to update Windows Defender Offline?

Windows Defender Offline helped me to get rid of a Trojan that had taken over my laptop, so many thanks for that. However, I have another Trojan now, a month after the first, so I need to know if the same Snipca link ( gives me up-to-date software, or does this number change with time? I have just made a DVD using my desktop computer and ran a complete scan on the laptop with the downloaded tool, and it hasn’t found the Trojan. I have the 64-bit version of Windows 7 Home Premium.

Solution : Do I need to update Windows Defender Offline?

If burned to a DVD, then Windows Defender Offline should be considered useful only for one (or short­-term) use. This is because by its nature the downloaded virus definitions it holds will not be updated – it is an offline tool, so does not connect to the online world. If copied to a USB stick key, however, then the program will update itself before running. As such, if you want to use Windows Defender Offline again via a DVD disc, then you should download the program again, as Microsoft regularly updates the virus definitions. In other words, only a newly downloaded version will contain the latest virus information.


You should not reuse a DVD version of Windows Defender Offline

However, our Snipca link ( will continue to work as long as Microsoft keeps the same website address for Windows Defender Offline. This is because all our shortened addresses do is ‘point’ to another page (Microsoft’s own download links are updated regularly).

Whatever has infected your PC, the latest version of Windows Defender should be able to find it. Are you sure that you didn’t accidentally create your new Windows Defender Offline DVD from an old version of the download? If you download a new version of the tool to the same folder, then it may, for example, be named ‘mssstool64 (l).exe’, rather than ‘mssstool64.exe’. If you double-click the mssstool64.exe file, you’ll simply be creating a DVD with the old version of the tool.
