Any recommendations for a non-intrusive antivirus?

[Android Central Question]

I'm looking for an antivirus (ideally free, but I'll pay if need be) that sticks to being an antivirus. In other words it doesn't check the phone/tablet temperature, tell me about junk files, ask me if I'd like to speed up my phone, or anything else. It's content just to let me know (or can EASILY be configured just to let me know) about viruses, malware or potentially evil websites.

Recommendations welcome.

Thanks kindly,
- Richard

Just to let you know you're not being ignored, but I've never found one. I use Avast Mobile Security & Antivirusbecause I use their product on my desktop, but it warns me about PUPs, junk files and the like (not temperatures, though).
