i could find internet security programs,antivirus ,firewall,malware programs,,which one do i need to install ?
currently ESET smart security and AVIRA antivirus both are running on my system..any problem if both smart security and sntivirus are installd?
please help

if you have “ESET smart security”, then it has everything. (Antivirus, Antispyware, Personal Firewall, Antispam, Parental Controls, Internet Security Training). because its a full security suit package. “Avira Antivirus Premium” is also like that. but “Avira Free Antivirus” does not contain everything. it lacks firewall, antispam)
do not keep 2 antivirus products running in your computer since it may slow down your computer.
A firewall is a device or set of devices designed to permit or deny network transmissions based upon a set of rules and is frequently used to protect networks from unauthorized access while permitting legitimate communications to pass.
Internet security is a branch of computer security specifically related to the Internet. Its objective is to establish rules and measures to use against attacks over the Internet. The Internet represents an insecure channel for exchanging information leading to a high risk of intrusion or fraud, such as phishing.
Antivirus is used to prevent, detect, and remove malware, including but not limited to computer viruses, computer worm, trojan horses, spyware and adware.
Enjoy..
You only need to install a Antivirus and a Firewall,so i recommend Comodo Internet Security it comes all in package and is FREE!
