Windows 7 - "You need to format the disk" bug/error/virus

Hey guys, how are you =)?

I'm here because a few days ago I got a big virus. I removed it successfully, but something that I could not solve is that everytime I plug in a pen drive or a sd card. It will not read it and it says

"H:\ is not accessible.

The volume does not contain a recognized file system.
Please make sure that all required file system drivers are loaded and that the volume is not corrupted."

I know it's not the pen drive or sd card because I plug them in onto another desktop and onto a laptop and they work.

So i'm guessing something was messed up in the registry, settings, or something else.

Any ideas on what I should do?

Sounds like a fresh reinstall of windows may be in order....

You might want to try a repair install using your Windows Seven disc.

If you have a restore point from before the virus struck, you may also try a system restore.
