This number is a scam for some alien country, I spoke for a person with very strong European or Arabian spelling, they ask me for pay in order to unblock my safari. I can't bel4eavew it, I don't know how to fix it.
Sounds like fun lol thanks for annoying them! There is no one more deserving of having their time wasted than these cretins. Wish I had time to do some aggravating myself.
Reinstall your computer from scratch. Once you give someone access to your computer, and especially if your account has "administrator" rights, then they have the ability to install just about any spying software they want on your computer. The only way to be sure you've got rid of it all is to reinstall from scratch. If you're keeping backups, then it is probably safe to reinstall from the backup as long as the backup occurred before you gave them access to the computer. If the backup drive was connected at the time they had control, then there's no guarantee that they didn't install their malicious programs into the backup, too. If you can't be _absolutely sure_ the backup is not poisoned, then don't use it: install from scratch. Install all your programs by re-downloading them from the internet, and copy your personal files over from the backup one at a time.
