I have a computer with Windows XP SP1 installed.
In addition the follwing softwares are installed:
Norton Anti virus 2005
Spybot S&D Tea Timer
Web Washer Classic
Ad-Aware SE Personal
lately pop up windows appear when I visit any site . For example as I was visiting "Experts-exchange" and writing this question a pop up window appeared and in the address bar I think was written:
Another pop up window has I think the www.adultfinder.com
address, it usually appear when I visit adult sites.
At other times at the address bar of the pop up window would appear the spy site address and the name of the site I am visiting at that moment such as www.yahoo.com
In addition, at each computer session "Zone- alarm Pro" would display a warning that it blocked a contact with a spy site such as www.imagesrvr.com
How can prevent these pop up windows
