Everytime I download it pulls up with same public address

So I’m trying to set up a new wallet because it appears u was hacked. I know I used metamask.io but Everytime I download it pulls up with same public address. Shouldn’t I get a new one? I don’t
wanna lose anymore money, and it seems as though there’s no other wallet to use when swapping for idos
If you have any answers please help. I’m losing more money because I can’t participate without swapping.
Thank you!

If you secret recovery phrase has been compromised, get an account with new secret recovery phrase, then the public address would be different.
