Only from a DVD/USB - its specifically designed this way to outsmart malware that requires booting into Windows to become 'aware' and then avoid detection, or hamper the malware detection process.

You can upload the install.exe file to VirusTotal
https://www.virustotal.com/
It will scan it and you may find more info on what malware is found in the file.

Neil3205,

If Sirefef was found on your computer, your interests are well served by running tools that query/diagnose the system prior to Windows starting.

Although some programs may come up clean, malware could still be lurking somewhere, particularly if it is a Rootkit.


So, if you agree, let’s take a look before Windows starts, but, need some info from you:

Do you have the Repair your computer option in the Advanced Boot Options menu?


To find out:

Restart the computer.
As soon as the BIOS is loaded begin tapping the F8 key until the Advanced Boot Options menu appears.
Is the Repair your computer option listed?


If you do not have the option, do you have your Windows installation CD/DVD available?


And last, do you have a USB flash drive available, and access to a clean computer?

Installed Windows Offline Defender

I am running this on my own computer on our home 'network'... as earlier advice in the thread... I have downloaded Windows Offline Defender on a CD and changed the BIOS to boot via the CD and did the scan by that... (at least a quick scan).... I will run a full scan while I sleep tonight as I fear that might take a few hours... the last re-boot I did the Sirefef wasn't showing.... now running an ESET scan....
