The most strong way is cold storage, you see bitfinex uses multi-sig address, but was still hacked, no secure in that way. 120k btc stolen, shcked!!!!!!! 
I don't think so? if you don't trust any online bitcoin wallet you can try bitcoin core but this is not safe also when your computer had virus or malware it's possible to affect your bitcoin. You should ensure the computer and a clean USB Cold storage before you transfer your bitcoin to your address. Actually I trust online wallet, I use poloniex addy. But I just say Cold storage is the safest one.
