Malware is a code that is for unauthorized use in the storage of sensitive information. A compromised WordPress website usually means malware was inserted into your website files, so look at files you have recently changed if you suspect malware on your website.
Even if thousands of kinds of malware infections occur on the internet, WordPress is not all vulnerable. The four common malware infections in WordPress are backdoors, drive-by downloads, pharma hacks, and malicious redirects.
All such forms of malware can easily be identified and cleaned up by manually deleting the malicious file, installing a new version of WordPress and restoring a previous uninfected backup on your WordPress page.
