i've always used lookout mobile security. it also has a "mobile locator" so if you lose it you can still find it..but i assume that won't work on a wifi tablet.
After having used lookout and a few others i can attest that Avast is wonderful. Can install the locator/wiper as a system app making it less likely the theif will get around it. Tons of great features.
