avast updates network shield to block malware URLs



Avast! has updated its Network Shield module to block malware URLs


In the past, some avast users have questioned if its Network Shield was actually doing anything…  it seemed as if the total number of items it checked was always listed as zer0.   In response to user queries, Avast explained that the only time you’d see the Network Shield count/monitor items was when an actual threat was encountered and stopped..


The latest update to Avast!, build 1282, has enhanced the Network Shield to monitor and block malware URLs (web pages).   For a specific test example, after updating to the newest version, if you were to misspell “Google” by typing-in 3 ‘o’s [rather than 2]:

www (dot) gooogle (dot) com

you’ll now notice a small popup [Avast! On-Access scanner message] above the avast icon in your system tray, advising you that the

Network Shield blocked access to the malicious site www (dot) gooogle (dot) com

--- and accordingly, that webpage will fail to be displayed in your browser(s).


[Related note:   For people who don’t have avast, but use OpenDNS, you’ll find that OpenDNS’s  typo-correction feature  will automatically correct this particular typo, and take you to the proper google.com (2 ‘o’s) website.]


The latest version of avast can either be downloaded automatically [for those users who have set avast to automatically download PROGRAM updates --- please allow time for its servers to “push” this update over the next few days], or manually:

RIGHT-click on the avast icon in your system tray,
