|Not enough information. |
Without any more details the only things I can suggest are:
Run your Antivirus and download > install > update > Run "MalwareBytes" (free version). See if they find anything.
Search for your email address in Google. If it finds it you will need to change your email address, then never put your email adress on the Internet again (Spammers Engines find it).
If the above do not help, contact your server for assistance.
Google is NOT the only Search Engine!
