AVG Online Web Page Scanner
The AVG LinkScanner® Drop Zone lets you check the safety of individual web pages you are about to visit. You may have received a suspicious link in an e-mail — just copy the URL (web page address) and drop it into the box below. LinkScanner® will examine the web page in real time to see whether it's hiding any suspicious downloads. Even innocent web sites can contain hidden "drive-by downloads". Use the AVG LinkScanner® Drop Zone to inspect:
- Links forwarded by friends
- URLs displayed by search results
- Links containing odd characters
- Any site you've never visited before
