Bleach??? A suggestion for the future - ask before taking a radical step. Chlorine bleach is a very strong oxidizer. That alone could be the end of your weakened plant. I have heard of using a bleach soak too; I would be reluctant to do so due to risk of killing the roots and damaging the leaves.

Mites usually leave a red to orange-yellow smear on a cloth dampened beforehand. The mites are usually pale yellow to red-orange. White specks could be something different (juvenile scale, thrips, or mealybugs).
Because you had insects, I would not conclude virus yet. A secondary infection (fungus, etc.) is certainly possible. I would isolate the plant though, if you want to nurse it back to health. If the roots are alive, and remain alive, you may have a chance.
