There isn't a specific "about:blank" virus as far as I know but at least one banker trojan has been known to reset the home page to about:blank in IE. Mind you this was about five years ago, and on XP.
So what is the OS here, and which browser and version?
Thanks so much for your link to about.blank. It appears that you have gotten rid of it for me after I followed the instructions. Whew, what a nightmare it was getting rid of it and having my home page back. Much appreciated.

Took your advice too and bookmarked that page. What a helpful community forum. Been on some others and found no help at all.
