I am using a free jQuery script for the frontpage of my website here: American Made Signs | Sign Company Charlottesville, VA
What it does is you click a smaller image and it displays it in the top container larger.
SiteLock has alerted me that it contains malware from a .pl extension or website. This is the first problem it's ever had in almost 3 years of being up.
Nothing in the script contains the alert problem. So it must be remotely connecting to it.
Should I leave it? or what alternatively do I have to this code? PHP? JS? jQuery?
