Thread: help me please: "This site may harm your computer"

Hi,

Please, I'm new in this forum and on using google products at all.

I have some questions about this issue
we added a script in our website from about one year ago and last week, the message "This site may harm your computer" displayed under our website in google results search page. We checked the google webmaster tools and find malwares (signed to the script added before a year).
I have the following questions:

1. Did google update anything to discover this now? why it didn't discover it before?

2. how can I test my script before applying it on my website to prevent this in the future?

3. How can I know if anyone hacked my website?

4. Can I add someting to receive a notification email before adding "This site may harm your computer" message in google results page?

Please, I have to know the answers, and there is no way to ask google about this since there is no email support.

I'll appreciate any help in this - Thank you

1. I know Google keep improving on this. However, they are usually do not reveal too much details on the algos etc.

2. There's a feature in Google Webmaster Tools that allows you to check your site.

3. Check your server logs.

4. Not sure, perhaps there is an alert feature in Google Webmaster Tools for this.

Maybe this can help:

3. How can I know if anyone hacked my website?

If it was just client-side script such as Javascript then there's very little any potential attacker could do.

Could you post the script in question here (in [code] tags)?
