not this much lol - its not happening to me and i have avast
webshields off: 15Mpbs
webshields on: 7Mbps
doesnt make THAT much of a difference - persoanlly i think its corrupt code in his Avast or Flash thats messing with the speedtest results
also if webshields are turned off - will file-shields still scan the web files on the PC? or is this process set dedicated to web type files like html, css, js, aspx, php etc etc and these files missed out by file shield?
