Google Chrome Detected: Trojan-Downloader.JS.Agent.gmr
I use AVG free and I didn't receive any warning, and everything looked fine on my computer, but as a precaution I asked the developer to disabled the site, whilst we fixed the problem.
Unfortunately I have no idea where to begin and the developer doesn't appear to be interested in helping.
Is there an easy to understand 'tutorial' to help locate and remove this Trojan Horse - or do I need to contact a WordPress Expert for help?
