Back to "Other errors"
Latest update: August 27, 2021 ID: 15335

This article concerns: 

  • Kaspersky Security Cloud
  • Kaspersky Internet Security
  • Kaspersky Anti-Virus
  • Kaspersky Total Security
  • Kaspersky Small Office Security


You see a warning "Prevented visiting a website..." or "Visiting an untrustworthy website has been prevented" when trying to open a website.


Kaspersky applications may block access to a website: it may be displayed incorrectly or fail to open completely. This may occur due to the following reasons:

  • The website may contain phishing links, malicious code or other threats.
  • When the website is accessed, content from the higher-level website may be loaded, which may be considered unsafe by Kaspersky Security Network.
  • The website may contain content considered sensitive (Adult content). If Parental Control is enabled, such site will be blocked.
  • Issue with a website certificate
  • Other causes unrelated to threats.
If you are the owner of the website which is blocked, see this article for instructions.


If the notification says that the website is infected, we do not recommend following the instructions below and opening such website.
  • If the blocked website is secure (HTTPS), try adding it to exclusions from Encrypted connections scanning. See this article for instructions.
  • Disable running of scripts for interacting with web pages: Go to SettingsNetwork settings. Clear the Inject script into web traffic to interact with web pages checkbox and click Continue. In the lower-right corner, click Save → Yes.
  • If you have Kaspersky Secure Connection installed, try disabling it.
  • If the issue occurs on a banking or payment page, try disabling Protected browser for this page. See this article for instructions.
  • Scan the link using OpenTip. If the link was identified as safe, add it to Trusted list. See the guide below.
  • Make sure that the Kaspersky Protection extension is installed and enabled in your browser. For instructions, see this article.
