Virus asking permission for keychain
I have a Macbook pro-Retina 13inch, mid-2014 running High Sierra version 10.13.3.
I recently used a USB stick form a friend of mine after which I am having this unusual notification of asking access to my keychain whenever I activate Siri, I believe its a virus from windows os.
I have attached a screenshot of the problem that I have mentioned.
Please help.
MacBook Pro with Retina display, macOS High Sierra (10.13)
