Hey everyone!

Lately, I've been having a troubling issue... I'l start from the beginning...

A few days ago, I decided to replay my old versions of Pokemon Yellow and Red. When I booted Red, there was an old save. The characters name was "STEN". I don't remember using such a name, but since the last time I played the game was ages ago, I thought it was normal and decided to check out the save. I started out at the entrance to the Digglet Tunnel. In the party, there was a Charmander, a Pidgey and a Rattata. The names, however, were really messed up (Ex.: KMNJ UE). It was really odd cause I never gave nicknames to my Pokemon.

I started a new save without any problems. I defeated Misty and went on. However, when I rebooted, the save had reset back to "STEN"!

I decided to boot up yellow. Same thing...
Character's name was "STEN", he was in the entrance to the Digglet Tunnel and in the party there was a Pikachu, a Charmander and a Pidgey and a Rattata. Whenever I rebooted it, the save would go back to "STEN"

I know there are a lot of Creepy Pastas about Pokemon, but I am in no way implying that my game is "haunted".

What I'm afraid is: Did my gameboy get a virus? Did my games get a virus?

Can anyone help me with this issue?
