In the context of computers and internet, choose the odd one out from the following:

Question

Accepted Answer

The correct option is (4):
Comodo is the odd one out because it is the name of a globally recognized cybersecurity company that develops and sells a wide range of security software and services, such as antivirus protection, firewalls, and digital certificates. In the context of computers and the internet, Comodo represents a *protective* or *defensive* entity—an organization whose purpose is to stop malicious attacks. This function fundamentally contrasts with the other three options, which are all names of infamous, destructive malicious software (malware) that have caused significant, widespread damage to computer networks worldwide. The key conceptual difference is that Comodo is a *solution*, while the others are *threats*.

The incorrect option is (1):
Code Red is an incorrect choice for the 'odd one out' because it is a famous malicious software program. It was a powerful computer worm that attacked in 2001 by exploiting a vulnerability in Microsoft's Internet Information Services (IIS) web server. Its notable action was performing a denial-of-service (DDoS) attack on a high-profile website, categorizing it as a major cyber threat.

The incorrect option is (2):
Melissa is also an incorrect choice as it is a historically significant piece of malware. Released in 1999, it was a fast-spreading macro virus distributed primarily through email attachments. The virus was designed to automatically mail itself out to the first 50 contacts in a user's address book, causing massive email traffic overloads globally.

The incorrect option is (3):
I Love You is an incorrect choice for the odd one out because it, too, is a notorious example of a computer worm. Also known as the Love Bug, it was released in 2000 and is regarded as one of the most economically damaging pieces of malware ever created. It spread via email with a deceptive subject line and attached file, which, when opened, resulted in the corruption of user files and the self-propagation of the worm.
