Malware is the intrusive and excessive DRM that Steam provides for the benefit of their game publisher clients and which you get to buy and live with. Hey, if you enjoy putting up with that sort of thing, by all means, buy from Steam.
Notice that you don't see any postings on SubSim about whether the version of SH3 (or SH4 or SH5) from any reputable vendor is modifiable. Just about the version someone bought from Steam. If they are all the same, why is that?
