I used this and its been working. It was scanned on my pc with avg before it went to my ouya and scanned with avast on the ouya and came out clean.
Only started getting a flag after I did a scan on avast, but it wasn't a virus flag, it just kept saying something like this program aint working correctly or correctly installed
or something. Installed avast and everything been fine. I probably would have tried the reroot script or whatever its called if I would have looked around and seen it before this.
