As others have said, Fitgirl is a major player in the games piracy scene. She doesn't crack the games, but she does repack cracked games (compresses them in clever ways). It's quite common for people to impersonate her or her site to try to fool people into downloading malware. This seems to be another one of those.

She warns against this quite frequently. From her faq, for example:

"Q: Do you have a Facebook page? A: I didn’t, don’t and won’t have a Facebook page. The same applies to Twitter, Instagram, whatever else. This site is the only official FitGirl Repacks source. If you happen to come here from “Facebook FitGirl Page” – you’ve been fooled by an imposter. "

(Note: this comment is not an endorsement of games piracy, and this community is not the appropriate venue for discussions of that nature. Anyone interested should go to relevant communities like the ones hosted on the db0 Lemmy instance )
