The company that I work for was recently informed by somebody that tried to view the source of our homepage that it prompted him about a virus.
We looked into it and found a 1px by 1px Iframe from
<another site>.
It's since been removed, but I was wondering if anybody had any idea how it could possibly have gotten there or had a similar experience.
We design and host websites, so we want to make sure that this doesn't happen to any of our clients.
Thank you to anybody that can help.
