Is it possible for a series 40 mobile set like Nokia 3110 classic to be infected by VIRUS? Why there is the restarting problem is this hand set more than other 40 series set?

see... maybe all of us is having problem with the "Restarting thing" that this phone does... Coz actually i am bothered with it.this handset is good from my opinion.but have a big problem that it have most probably MMC prob.,whenever entered switch off and again switch on,2 times given in Nokia care service center but no resolution,and many of my friends are also facing same problem.plz resolve handset manufacturing defect prob..
