A class 10 card is not a requirement for Windows Phone 8.1. It is a nice-to-have, but not required.
You don't have a virus, but I'm not sure what you mean by "scrambled" - like out-of-order?
There are no virii on Windows Phone, so there naturally is no anti-virus. (Although it wont stop people from trying to sell it to you)
