My phone is getting slower. Help me please  

Every virus can't be detected with any particular anti virus. You can do one thing. Copy all the necessary contact and document. Life out the memory card. And then rest your mobile. You card can be done virus scan in pc.

I think your phone attacked by virus.. or you downloaded mostly software and other tools in your mobile.. so it's phone memory were affacted.. now you may raise your memory of phone..and scanning your phone with a good antivirus.. thanking you and keep mylotting always..

All you need to do is upgrade firmware. It's going to erase all your data but the phone is going to run faster. Just do a back up before doing this

really? my niece is even recommending this to me. what can you say about this? except for the slowing down, are you satisfied with it?

I've never personally used one of my cellular phones for internet access so I really know nothing about a phone slowing down due to having a virus. The one thing that I think is plausible is that you are using too much of the memory within the phone. Again, I don't know a whole lot about high tech phones, but I do believe that if you are using the memory then it is going to cause it to slow down to a great degree.
