rooting - How can I root my Yarvik Tab411?

How can I root my tablet, the yarvik tab411? I tried to find information on the internet, but had no success.

The tab runs Android 4.1.1¹ 2.3.3.

¹ according to the link, this device currently ships with Android 4.1.1. Marrssel has an older version, running 2.3.3. ^{(comment by Izzy)}
