    Hi All,
    Does anyone know how to clean a asp application from a
    virus that converts labels with the word 'Insurance' into
    link button to a web page. It also injects text in the
    textbox when the textbox.text has any reference to
    this 'insurance' word.

    I am using custom controls on custom page. This injection
    seems to be occurring after the pre-render event.


    Thanks in advance.

    Before you resort to drastic action consider whether the 'virus' is infact a 'Browser Helper Object' (BHO) distributed with free/shareware software. These are frequently installed on the back of systems like Kazaa with little explanation of what they actually do.

    One example is Adware, this loads a BHO into Internet Explorer. The BHO reads any HTML text looking for common keywords, then replaces it with an Ad-link. Similar to the symptoms you describe

    There are many removal tools on the market, one that I've used before is Ad-aware by Lavasoft (www.lavasoftusa.com). Removing spyware may stop some free/shareware programs from running. Remember nothing is truely free right?
