watch out ! Antivir PP might cause you lost of url in your IE7 favorites. Symptoms: your favorite links, those you go to the most, randomly, NOT WORKING ANYMORE. At first , I thought it was CCleaner. Only recently, I found it likely could be Antivir PP. I am saying Antivir Personal Premium. I am not sure about Antivir CE so lets leave it out unless you use it and have same symptoms.
