The valley of secrets

He's trying to get me to download some iLivid thing. My browser and antivirus are flagging it. Is this something I should be downloading?

No, no, no. I haven't checked it. If that's the case, you shouldn't download it. iLivid is clearly something untrustworthy.
Looks like you need to find someone who has already downloaded it... Or look for Mamaich.
