Don't trade with any unlicensed broker.
1. As per my search online, CFD brokers are banned in Malaysia, and it is not legal to trade forex via any online CFD broker. SC of Malaysia have published an investor alert list & most CFD brokers are on that list.
2. Plus, from what I see on their register page, Exness also does not accept Malaysian traders (screenshot, there is no Malaysia on selection of Country of Residence).
3. OP, in your screenshot, it is not Exness that is in their alert list. It is some scam/clone broker trading using Exness name. But it also does not mean that Exness is legal in Malaysia.
I suggest that one should avoid trading forex or CFDs if you are from a country where CFDs are banned & there are no licensed broker. Foreign/Offshore brokers, even if they are tier-1 regulated are still not legal. You will not get any investor protection of your funds.
