Hello

My Note 2 has suddenly started to slow down and lock up.
It is 4 months old and been perfect until today.

I have scanned the sd card, no issues.
Cant find out how to scan the machine itself.

I have deleted one of the two apps that AVG identified as 'malware', both games that had been fine before.

I regularly close down apps through the task manager

any hints???
help please
