These applications are considered malware and they should be removed as soon as possible because such applications can steal your social information related to credit cards, bank accounts, account with passwords and usernames, etc. You can either use Malwarebytes Anti-Malware for a quick solution or if you want an advanced removal, you can use Combofix.
You can use both applications but I recommend on using Combofix as the removal process is entirely automatic and 100 % safe.
Download and install any of these applications and perform a scan of your computer. Malwarebytes will offer a reboot after the scanning operation finishes while Combofix will continue to run after the initial scanning.
