Welcome Sudiar.

What is the exact message that tells you your device detects a virus? A screen capture posted here in the forum would help others understand your problem. Otherwise, your issue is probably discussed in the above Forum links.
You probably DO NOT have a virus. Your Android only 'thinks' it does. Please read the links.
Please explain. What did you change in your Project?
