How do I remove the virus?

[Muntasling Fabling]

It has affected my battery and now my phone (Xperia Z1) switches off when the battery reduces below 90%.
I have AVG Pro installed but it says "no threats" whenever I scan. How do I fix it?

Posting the same question twice won't necessarily elicit an answer. It's a tricky one.
