This is related to AdWatch which is in the paid version and alerts/prevents registry modifications. I don't use AdWatch but it is my understanding that it will alert to any new registry settings regardless if they are harmful or not (because it can't tell the difference) and let you accept or block unless you have "automatic blocking" enabled.
What were you doing prior to receiving the alert besides surfing? Did you install Ewido as just prior to the alert?
Can you post that portion of the log so we can see the details. It should look similar to these examples:
12/29/2004 11:03:13 PM - Registry modification detected
22/05/2005 05:45:42 - Registry modification detected
New Data:C:\WINNT\Fonts\lsass.exe "%1" %*
Please don't start a new topic for each problem. This makes it harder and confusing for anyone to help.
