I face this issue that one day someone has stolen my ether wallet private key, I do not know how because I had enter my private on any website.
Now I am using Meta Mask but I am not 100% sure that it is safe from all types of hacking attempts.
I cannot effort hardware wallet please tell me any software that make impossible for hackers to hack my tokens
I assume you meant you haven't entered your private key on any website.
May I ask which wallet you used before Meta Mask?,that got compromised?
I personally use
https://www.myetherwallet.com, or
https://github.com/kvhnuke/etherwallet while offline. This way the wallet is "cold".
I've checked their code, and haven't found anything malicious.
