Installing Comodo Internet Security was a series of simple steps. The installation file is a self-extracting one, and there are no surprises during the initial stages.
After accepting the license agreement and choosing the destination folder for the installation, the user is then presented with the choice of installing the Antivirus and the Firewall components of the Comodo suite. By default, both boxes are checked and recommended.
As a word of caution, the installer recommends that any other antivirus programs that are currently installed should be removed. Two antivirus programs do not mean greater security, as one would be forgiven for thinking. It tends to be counterproductive, therefore the best course of action is to have just one operating at any given point of time, with the latest updates and program features. Usually this check is performed towards the end of the installation, which means a user ends up wasting their time with an incomplete installation before having to uninstall the older software first. Comodo’s timely word of caution does end up saving some time, even though the installation itself doesn’t take very long.

After selecting the products that need to be installed, there is a screen prompting the user to join the Threatcast community. Again, by default the option has been selected. Threatcast will be discussed a little later in the article.
The user has a choice to subscribe to email newsletters from Comodo, which will contain news updates among other information.
The installation will then complete with a malware scan that Comodo will perform. The scan time will vary significantly from computer to computer, however the overall installation excluding the scan takes about 3-4 minutes only.
