How Can I Tell If This Software is Malware?

What kind of software are you dealing with? Is it an emulator or something else? That could make a difference in whether it's considered safe or not.

If you're worried about malware, it's always a good idea to run a malware scan. There are several reliable malware removal tools out there that can help you out. Just make sure you're using well-reviewed software to check your system.

For future reference, always check reviews from multiple sources before downloading anything. Ratings can be misleading, especially if they're from a single site.
