Norton Inability to detect some threats

Dear all,

I am facing a problem with Norton security 2015 since it can not detect some viruses and malware like Trojan.Agent-PUP.Optional.OpenCandy-PUP.Optional.Softomate.A-Trojan.ClickBot.

These virus turns files in USB storage device to hidden state, and slow down my computer

Note: These threats are identified by another software that clean malwares.

          Find attached results about scans on three infected laptops with Norton security installed.

Please find a solution to this thread.

Sincerely
