Simple job... I have a website that has been hacked, below are the details given by google. I need it taking down, cleaning and reuploading, and a description of what has been done. Please provide a TOTAL PRICE for the job in your response. Please note: I will submit a reconsideration request to Google and payment will be approved when google confirms it is clean. We are writing to let you know that we believe some of your website's pages may be hacked. Specifically, we think that JavaScript has been injected into your site by a third party and may be used to redirect users to malicious sites. You should check your source code for any unfamiliar JavaScript and in particular any files containing "iframe name=Twitter scrolling=auto frameborder=no align=center height=2 width=2 ". The malicious code may be placed in HTML, JavaScript or PHP files so it's important to be thorough in your search.
