I want to download bitcoin core program my computer are there any security risk I should worry about? I have Ipvanish vpn and also Mcafee install on my computer. Any suggestions I will appreciate it.
about security No, you only need to download it from official source and have enough space and time for sync.
Some antiviruses give false reports, so ignore them as long as you download from the official source.
Regarding privacy, Ipvanish vpn is not a good option, you need to install Tor properly for extra privacy.
