Given that this is in the admin area of your site I doubt we can actually investigate it from outside.
Check your php templates, as that is a common way for paged to get infected/hacked, ensure that you have the latest version running on your host/board software.
I got help over at Jcink support. Removed a piece of code. They say sometimes you can get a false report. Anyway, after removing the code, I no longer get avast freaking out on me. Thank you.
The URL from the avast warning…is not the URL in question here…
this is the one -http://skinsandmore.b1.jcink.com so i guess there must have been a redirect to the one that show in the avast warning
What we have here is visitor counter malware.
Malcreants use a.o. following techniques to deter and confuse analysis. Obfuscation and/or the hiding of codes and scripts; insertion of useless junkcode; compression and encryption methods and this also for data (use of packers); malware checksum and protection routines to prevent tampering and patching of malcreations; malware may react differently when analysis tools are being found (different reaction to VM, monitoring and debugging tools when met by certain malcode).
