Hi Shlomo,
Thanks for quick reply. I understand that this is obviously not really a virus.
The thing is that I am not even using installer and I do not plan to use when the extension is complete.
This 1.js file is part of crossrider framework. And it is put in Quarantine by Norton as soon as you download the extension as zip in order for it to be added to chrome.
My extension Id is 56381.
The exact steps to reproduce are.
1) Go to extensions IDE in Google chrome:
http://crossrider.com/apps/56381/ide
2) Click "Install staging extn"
3) Click green "Download zip" button
4) Open the zip file in WinRar
Result: Norton warning is displayed.
If you ignore the warning and extract the zip and then do the "Load unpacked extension" - everything seems fine: you get the thank you page, the browser button is added and works, etc. It's just that extension.js code is never executed until you restore the 1.js from Quarantine.
Hope this is helpful. Let me know if you need more info.
P.S. I love crossrider framework and sincerely hope these issues will be resolved by the time I finish my extension:)
