So, are we sure this game doesn't contain maleware? I mean, is it the Dev who provides the Links or some random users?
We can never be sure a download doesn't contain Malware, Virus or other bad stuff, not even when the link is fresh from a Dev.
However we can scan the dowloaded file before and after extracting it, but even this is no guarantee!
Not trying to make people paranoid, but vira and malware etc. has to be known by your anti-vira programs database to be caught, or make an action that causes the program to react and block it.
Sometimes, new and unknown vira manage to creep into even Devs systems, hence why we are never 100% secure.
Stuff downloaded from Mega has a high rate of being safe, as they are scanned by the site. Other big and wellfunded upload sites have scanners running too, but again nothing is 100% safe.
On this site we users also report if our anti-vira programs find something, often it's false positive, and the Admins, as well as other users, react pretty fast if indeed a link turns out to hold something bad.
In conclusion, stuff from this site are pretty safe to download, not always 100% because nothing is, but as close as it can come.
