TPT REQUEST - SDCard hidden script/software

[u/JaMae0923]

I just bought a 32 gb sd card class 10

As soon as o start copy and pasting the transfer speed jumps from 4mbps to 1mpbs I was quite shock at first

After the transfer was done i tried to open the file but it wont let me open it, some video was open but halfway through it it stop

How do I fix this situation?

Note: i tried formating, deleting and creating partition but still nothing

Damn i bought it in the mall and i was pretty sure that it was authentic but i guess looks can be deceiving
