Tried out avast shield for Google Chrome with the eicar test virus. Google Chrome prevents the download, Google Safebrowsing alerts, MS Defender alerts the eicar download file, but avast shield does not work. Also had continuous problems with avast web rep in the Google Chrome browser. Assume it is the continuous Google Chrome updating and restrictive api access that is hindering the avast shield and extension. Funny because BitDefender's trafficlight and Trustwave Secure browsing are normally functioning in Google Chrome. No alert is shown, but the blocking in Google Chrome just is done...
