Is it permissible to open an account with Arab Bank to receive customer payments for a web hosting and web services company?

It is forbidden to open an account in a usurious bank because it involves aiding and encouraging sin. However, if there is a necessity, such as the absence of Islamic banks, then it is permissible to do so to the extent of the need. Furthermore, one must adhere to the Sharia guidelines in web hosting, programming, and web services. Thus, anything related to forbidden matters is not permissible.
