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

Question

Accepted Answer

The correct option is (4):
The word *Comodo* is the odd one out because, unlike the others, it is not a piece of malicious software. Comodo is a legitimate and well-known brand and company in the cybersecurity industry. They specialize in providing a range of defensive security products, such as Comodo Antivirus, firewalls, and digital SSL certificates, all of which are designed to protect computers and networks from threats. Therefore, Comodo represents a *solution* to security problems, while the other three names represent the *problems* themselves.

The incorrect option is (1):
*Code Red* is an incorrect choice because it is the name of a notorious computer worm that caused massive internet disruption in 2001. This worm specifically targeted Microsoft IIS web servers by exploiting a buffer overflow vulnerability. It is categorized as malicious software, making it conceptually similar to options 2 and 3. Its payload included defacing websites and launching a distributed denial-of-service (DDoS) attack against a specific IP address.

The incorrect option is (2):
*Melissa* is an incorrect choice because it was a fast-spreading macro virus released in 1999. It was one of the first widely publicized malicious programs to use email to propagate, mailing itself to the first 50 contacts in a user's address book. This virus also modified documents within a Microsoft Word file format, confirming its identity as a type of malware, just like Code Red and I LOVE YOU.

The incorrect option is (3):
*I LOVE YOU*, also known as the Love Bug, is an incorrect choice because it was a highly destructive computer worm that spread globally in 2000. It utilized social engineering, disguising itself as a love letter to trick users into opening the malicious email attachment. Upon execution, the worm would corrupt files and steal user credentials, cementing its place as a significant and damaging historical malware event.
