What is Malware?
It is malicious software specifically created to gain access or damage a computer without the knowledge of the owner. Viruses, worms, and Trojan horses are examples of malicious software that are often grouped together and referred to as malware. Malware can open access to your personal information, such as passwords and credit card numbers or alter your search results without your knowledge.
How to fix the issue
Below are some suggestions how to resolve this issue if it is happening to your site:
1. Scan and remove the malicious content from your site.

3. Register and verify your site in Google’s free Webmaster Tools.
