Operation did not complete successfully

[Va1mar]

So, was playing earlier today, had to quit real quickly.

Saved and exited game, shut down computer. 

Came back and tried to start it, wouldn't connect to server. Quit out, and the file was gone from underneath me when I tried to restart it. 

Re-installed the launcher and it tried to update the game but it keeps stopping itself...

 

"Error: Operation did not complete successfully because the file contains a virus or other potentially unwanted software."

 

Any tips for what I should do?

Nevermind. 

Figured out how to block my security from the trojan flag.
