Suppose that you click on “I accept” in order to download software from the Internet. You do not read the terms of the agreement before accepting it, even though you know that such agreements often contain forum-selection and arbitration clauses. The software later causes irreparable harm to your computer system, and you want to sue. When you go to the Web site and view the agreement, however, you discover that a choice-of-law clause in the contract specified that the law of Nigeria controls. Is this term enforceable? Is it a term that should be reasonably expected in an online contract?
If it's in the contract, and you accepted it, it is binding whether or not you read it, unless that contract somehow violates the law where you live.
One could reasonably expect almost anything from an unknown software provider on the Internet. I would always use extreme caution before downloading from sites I don't know to be reputable. A good way to check that is www.mywot.com (no reputation established there is also a red flag).
