Yes, if I use another browser, then I can get it to work and unlocked. But, I just wasn't sure if that was just the solution I should go with, or to actually try to get rid of the virus. Perhaps I should just uninstall the default browser? Also, I'm not entirely sure if there are other problems too, as I've avoided using the tablet ever since it has been infected.
Also no, the tablet is not currently rooted.
