Please can you check why the spirit software is picked up by antivirus as containing malicious code.
Can't be too careful these days, and don't want to install until sure this is safe.

Hello,

unfortunately from time to time antivirus are flagging software as malicious.
I am afraid we can't do anything with this. You can use online scanner to verify it by a multiple softwares. You will see it will pass the most normally.

It is only important to download from official Spirit web page.
