A Day Ago I Connected My Lumia 625 To My Pc Which Is Also A Windows Run PC And Probably Has A Lot Of Virus In It. After Disconnecting My Phone From The PC, Its Behaving Differently, It Does Not Show The Contact name When I Get A Call But Just The Number. And While Listening To Music It Only Plays In One Earphone Whereas The OtherOne Is Completely Silent -_- . The Earphones Work Perfrectly When Connected To Some Other Device. Some Help Please ! Please Suggest Me Some Good Anti Virus Available On The Windows Store.
there are no antivirus in WP store, as there are no viruses.
the problem with ur phonebook, i.e. name is not shown up on call, mostly because u have double phonebook entries. and they might be hidden because u r not viewing all the contacts.
secondly, ur earphone not working properly, check two things. one is, whether earphone balance is changed (i am not sure about this myself, as i am unable to find such settings)
secondly, r u using Nokia headphones or others? i have encountered such situation, while using samsung headphones. i remember using it without calling part. i mean, they did came in two parts, one was regular headphones, and another was a 4 inches part, which when attached, the earphones worked well. otherwise, they worked well only on samsung phones, not with others.
