I've got a Nokia Lumia 630 and its been acting abit strange lately , like screen moving around by itself and closing web pages, I have been reading up on it on google and what I gather is people say these phones cant get viruses but I not so sure myself , is there any apps or sites that will do virus and/or malware scans for this phone ? I've been hunting but I cant seem to find anything .
Thanks for your time
