I don’t aware of this feature in Google Desktop until one day it warns me about a potential harmful website. I thought all the way Google Desktop is doing indexing only. See the screen shot below:
At first, I thought this is something to do with the Google search engine. Eventually after a few times of this warning, I only realized it is something to do with the Google Desktop. It looks like the Google Desktop detects those sites based on the information from StopBadware.org. Badware could be some sorts of spyware, adware, viruses or Trojan horse programs
The website is http://www.digitalspy.co.uk/forums. You can try click it and see whether your browser can catch this or not. However, the website doesn't seems like have potential thread but to be safe, I didn't continue browsing in that website.
I think “Safe Browsing” is turned on by default. If not, you can perform the following instructions:
- Go to preference page.
- Click the “Other” tab at the top.
- Tick the “Enable Safe Browsing” check box.
- Click “Save Preferences” to apply the change.
