You can't recover BCH from Electrum... You need to use a BCH compatible wallet like ElectronCash.
www.electroncash.orgIf you had BTC on addresses at the time of the fork on Aug 1, then those addresses will contain BCH now, regardless of what you did with your BTC after August 1st.
there was some suspicious about electron cash... now their software is working fine?
Yes the software is fine. It was developed by Fyookball (a member here).
If you want to increase your security then it is still advisable to follow the steps previous but it doesn't look like there's an issue anymore (it was just the developer wasn't know - but now they are).
