I looked online and found this:
- Clear your system’s DNS cache to sever connections to malicious software programs
- Utilize a program or tool that deleted browser hijackers and modifications, or one that scans for and removes spyware
- Reset your browser homepage settings. In more extreme cases, uninstall and then reinstall your browser.
Hopefully, it will help. You can also install Malwarebytes (at least the free version) to run and see what it detects.
All the best,
