According to the internet, aria2c is a lightweight multi-protocol & multi-source command-line download utility. It supports HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink. BitTorrent I think is what is currently being used for Feral Heart's preset sync. So, if you are using preset sync or have recently downloaded it, aria2c isn't something to worry about. Norton is an overly protective anti-virus. The anti-virus is pretty much an equivelant of baby proofing areas of a house for a young adult. Yeah..
As for 7zipsfx.000, it doesn't appear to be a virus otherwise I'd imagine Norton would have picked that up already. But of course, if you feel comfortable with running an anti-virus scan, then you're more than welcome to. Have you recently installed the 7zip SFX program? Or 7zip? Because this is what it seems to be.
Woohoo! All up and running with no malicious signs yet.
I just can't get into the game. It says "connection to front server failed". Help? xD
Glad that you could download the game!
And all you need to do is to keep the PlayGame tab open at all times while you play

If it keeps reconnecting you, you can try using a web refresher!
