Investments and shares

Q: what about online jobs on the internet. Can we invest in any online company on the internet & get profit from it. www.zeekrewrs is a such company. Can you get information about it & explain it in the light of Islam?

Q: I have a question about investing money in the Bank. Few banks are offering me to open a monthly saving account. They are promising me a profit of 11.5% every month for investing with them. I will be receiving this amount without losing my investment. Is this permissible in Islam?
