Abandonment not safe?

Last night I down loaded zoo tycoon 2 from abondonware. I couldn't get it to work so I deleted it from my system. Turned my computer off and went to bed. This morning I can't get on the internet (I'm on my phone) and my aura VPN network is being blocked by a Unified Wintin. Ive never download that program. My system was fine until I trued to download ZT2......
