Most of the new virus software can check files in detail and will compare it to online databases to check for viruses. In case you don't use a good antivirus program you can also check online on some websites. For example on https://www.virustotal.com/gui/home/upload you upload the file and they will check it for you. This will not tell you if the bot is legit or scam though. Since you already bought the bot you must have decided for yourself that it's not a scam, but I would still recommend you to be cautious and test the bot. It might be hard to fully understand the bot at first, that is why I would start very small and only use little money to try out the bot. Only if it makes you money consistently you should consider adding larger betting sizes.
