I am helping a friend install OneNote 2013 64-bit on their Windows 7 (64-bit, SP1) system.
We went to the official Microsoft OneNote website, www.onenote.com, clicked on 'Windows' (just to the right of 'Get OneNote for free on all your devices'), then clicked on 'Other download options' towards the bottom of the page. This displays a 'Free Download' link, which, when clicked, downloads the MS installer for the 64-bit version.
The URL of the installer is:
We scanned the downloaded file using Avast 2015, and there were no problems reported. We then ran the program, and Avast brings up its big alert stating "Virus Found" (object: onenote.exe, process: officeclicktorun.exe). The infection name is "Win64:Malware-gen".
Can other people try this out and see what happens. We are not sure how to proceed at this point. How do you tell if this is an infection or a false positive?
