What is HTTPS scanning in Avast Antivirus?

HTTPS scanning is a feature of Web Shield in Avast Antivirus and is automatically enabled when Avast is installed. HTTPS scanning decrypts and scans encrypted traffic to detect potential mawlare contained on sites using HTTPS connections.

What is HTTPS?

HTTPS (Hyper Text Transfer Protocol Secure) is a more secure version of the standard HTTP connection. HTTPS adds encryption which prevents others from eavesdropping, and helps ensure that you are connected to the intended server.

For detailed information about HTTPS, refer to the wikipedia page below:

What is the benefit of HTTPS scanning?

While an HTTPS connection ensures that the connection can not be modified by anyone else, it does not guarantee that the content contained on the site is clean. Malware scripts and binaries can be placed into an HTTPS page that appears to be safe. The HTTPS scanning feature prevents you from downloading malicious content from sites secured with an HTTPS connection onto your PC.

Is the HTTPS connection still secure when Avast scans it?

When the Web Shield in Avast Antivirus scans the HTTPS connection, the data being scanned remains encrypted and secure. While HTTPS scanning is in effect, the Web Shield and your browser are on the same PC.

Is all my web traffic sent to the Avast servers?

No, all scanning occurs locally on your PC during the HTTPS connection. No one outside of your PC can read or decipher the connection.

  2. Same thing used to happen when I was using escan.
    It used to block browsers, and ip address of google.
    Check an option where it logs the blocked applications and ip addresses.
    unblock your browsers, and unblock the recently blocked ip addresses.
    Escan had the option of remove alert cache or something, so try to find a similar option to whitelist/unblock.
