Does anyone know yet, where this comes from. Very curious!

According to the post in link below you should be able to uninstall DefaultTab.A in the Add/ Remove program.

Give that a try (the post is from the distributor of this adware/ crapware so it may not be the case). Please post

back and let us know if that actually works. If not, other methods are available to remove the DefaultTab.A.

EDIT: That post will answer your question as to how the adware got on your computer. There must be hundreds

of these types of malware being piggy-backed onto free programs these days. Seems almost all freebies now 

have adware that you can deny the install of and some you can't.
