Hi prunich,
Thanks for your post.
I am not quite understand your problem. It seems like the anti-virus software scan the viruses in the files created in your VS2015 Community?
As far as I know, the program created in VS2015 Community will not bring the anti-virus. If your create a new simple program in your VS2015 Community.
And use anti-virus to scan the file. You still get the file contains viruses. In this case, I suppose the cause is not in your VS, the cause is probably in your OS environment itself.
Also I suggest you'd better use VS2015 Community without using another anti-virus software to avoid some unexpceted errors.
If I misunderstood your problem, please feel free to let me know.
Best Regards,
Lake Xiao
