How to know a software found in phone is suspicious?

This is not easy to figure out. However, you can use an anti-virus like QuickHeal or F-secure or some others to detect any virus or worms in the phone. Also see any abnormal change like too frequent App crashes or some unwanted messages or battery suddenly draining out.
You might need to go for a Factory reset in the most severe case.

Oh my God, I hate all these viruses. Once they almost ruined my life. I am so frightened by viruses that I check my whole system on PC and phones every single day.
