I have recently bought a Kaspersky internet security software .But I have already installed AVG antivirus free edition.Now shall I remove AVG before installing Kaspersky?Also can anybody send me a link where I can know more about spyware,malware,antivirus etc.?
De-install AVG antivirus before you install Kaspersky internet security. Two different anti-virus programs are most likely going to interfere with each other. It's also not necessary to have two anti-virus programs at the same time, that will most likely slow your computer down unnecessarily.
