I downloaded the file Photoshop_Set-Up.exe from adobe, and virustotal detected "malicious_confidence_69% (D)". It's a false positive?
I got a warning from Frontier Secure when I went to the Adobe.com site to download the free Photoshop CC trial (https://creative.adobe.com/products/download/photoshop?promoid=61PM825Y&mv=other). It said that:
DeepGuard has blocked an application because it is not commonly used:
Reason: Rare application
I don't know why this is happening, but I decided not to take a chance until I know more about this issue.
You should report that to Frontier Secure have them check it out to verify that they know Adobe Photoshop is a rare application.
That's not saying it's a virus. Read the reason closely.
