I recently noticed that a Firefox toolbar get frequently installed on my parents computer. I managed to trace back the method it is using to get installed (through a link that looks like a Firefox window) but I don't know how to teach them that certains elements of a webpage can be malicious.
The toolbar name is "alot"; I'm not sure if it's really malicious, but I don't want the results of google to be manipulated.
I would like to be behind them as it happens. They are running Windows Seven, and I have several machines on the local network. I already know the domain name that I think the malicious toolbar is downloaded from.
