Where to continue my research-oriented studies after Bachelor's Degree in Computer Science?
The reason why you're not seeing scholarships for study at the master's level in Europe is that the master's degree is not viewed as the prerequisite for PhD study, but instead as the direct continuation of the bachelor's degree. As a result, you're expected to move on to the master's program, and usually at the same location you did your bachelor's degree. That means there really isn't a call for a lot of scholarship to fund master's study. However, it is possible to finance one's stay in a European university, as many schools offer part-time positions for master's students working in a research group for some number of hours per week. 

However, in the US and several other countries, gaining admission to a PhD program is a good way to get your master's studies funded, as the funding is normally provided for the entirety of your graduate tenure, rather than just the PhD portion.

To get in to most programs in English-speaking countries, you will need to show evidence of a good scholastic record as well as good English skills, as evidenced by the IELTS or TOEFL. If those aren't in place, it's going to be very difficult for you to be competitive, and almost impossible to be competitive for a scholarship or fellowship.
