F-Secure, maker of anti-virus and anti-spyware software for internet security, has acquired Steek,

a provider of online storage and data management applications for

mobile operators. The deal will expand F-Secure's portfolio of software

offerings, making it a more versatile choice for its customerbase, made

up mostly of mobile operators -- it will also bring new operators into

its fold.

San Jose, Calif.-based F-Secure paid $38.4 million for France-based Steek

-- but it may have to kick in $3.5 million more in 2010 if the acquired

business performs well for the company. F-Secure says the deal should

bump its revenue from $2.8 million to $4.2 million in the latter half

of the year.

Steek raised $8 million in a second round of funding last year from Innovacom and AGF Private Equity. Before that, it had raised about $4 million in 2006.
