Yes, all of our files are scanned for viruses prior to uploaded, and they are registered with VirusTotal and Kaspersky. It's possible Webroot hasn't whitelisted the file yet. What is the name of the installer file you are using it and from where did you download the file from?
Went to adobe.com. Searched Flash Player. Under Adobe Flash Player in the results, I clicked Download Flash Player. The file name is flashplayer24_xa_install.exe.
When was the last time you updated the Webroot virus definitions? I downloaded the file you used, falshpaleyr24_xa_install.exe and ran it through VirusTotal (free online service that analyzes files and URLs) used by many A/V software. None of the A/V companies, including Webroot report the file as being malicious. Results are available at https://www.virustotal.com/en/file/4d701152b8af671448c513e808086bafce7216091e01d2687c1d01b 8b7653e2f/analysis/ (a/v software listed in alphabetic order). You can also go to www.virustotal.com and upload the file you downloaded and scan it. I surmise the results will be the same.
Thanks for posting the screenshot. I'll forward to the online installer team, since this is the online installer that is being flagged by Webroot.
Did you upload the file you downloaded to VirusTotal? I expect it to be fine, but I'm interested in seeing the VirusTotal results for the file you have, especially the SHA256 hash value that will be displayed.
