Where is your proof that there is a virus? I had an experience with my 770 running OS06 that did the same thing as yours, but I caused it. I suspect you ran "apt-get upgrade" in there some where, if this is run on any 770 your have FUBAR your tablet. I just suggest reflash, and since you can only install one thing at a time your should know what you did to kill it.
For reference some one breaking their Linux is not a bad thing, it is learning, just don't blame messing up on a virus.
And what is with making a thread that links to your other thread in the same forum...
Not trying to be mean.
