I have Micromax A90s mobile I was using android 4.2.2. it was working fine. But few days back it suddenly started showing error that serval services are stopped working and it hung and reboot. so I decided to format it but when I format it it shows that formation is successful but when I boot it again it is on its previous state, like my data connection automatically enbaled programs I installed were automatically installed. I tried deleting data from my mobile internal storage that is 2GB.I deleted partition even I wiped partion using 7 pass method but as soon as I reboot my moble all data comes. This is annoying and pissing me off. So I just want to know that is it some kind of virus or maleware or trojan that is causing it and if it is then is it possible to remove it. Any help will be appreciated. Thank you!!
