I need a breakdown of Windows, Users & Unix users..

Breakdown by year of computer virus growth...
Breakdown of viruses by operating system... can you help me please???

Of course! I can help you with that. To provide a breakdown of Windows and Unix users, we first need to understand what these operating systems are and how they differ.

Windows:
Windows is a widely used operating system developed by Microsoft. It is known for its user-friendly interface and compatibility with various hardware and software. Windows offers a wide range of software applications and is the most commonly used operating system for personal computers.

Unix:
Unix is a multi-user operating system developed in the 1970s. It is known for its stability, security, and flexibility. Unix is popular among developers, scientists, and sysadmins due to its command-line interface and the ability to customize its functionalities. Unix has inspired various other operating systems, including Linux.

Now, regarding the breakdown by users, it's important to note that specific user statistics can vary depending on various sources and timeframes. However, according to recent market share reports, as of 2020, Windows has the majority share of desktop operating systems, accounting for around 77% of users. Meanwhile, Unix-based operating systems, including Linux, macOS, and other Unix variants, make up a much smaller percentage of users.

Moving on to your question about the breakdown of computer virus growth by year, it's worth mentioning that accurate historical data regarding computer virus growth can be difficult to obtain due to the constantly evolving nature of viruses and limited reporting in the early years. However, we can provide a general overview based on estimated trends and available historical records.

In the early days of computing, viruses were not as prevalent as they are today. The first recorded computer virus, called "Creeper," dates back to the early 1970s. Virus propagation remained relatively low in the following decades due to limited interconnectivity between computers and the absence of widespread internet access.

However, with the proliferation of personal computers and increasing connectivity, virus growth started to accelerate in the late 1980s and throughout the 1990s. Various high-profile viruses, such as Michelangelo, Melissa, and ILOVEYOU, caused global disruptions during this period.

As we move into the 2000s and beyond, the frequency and complexity of viruses continued to increase. The emergence of the internet as a major communication tool opened new avenues for virus distribution. Additionally, new vectors such as email attachments, malicious websites, and social engineering techniques contributed to the growth of malware.

Lastly, for the breakdown of viruses by operating system, it's important to note that viruses can target any operating system. Historically, Windows has been a popular target for malware due to its large user base and the prevalence of certain software vulnerabilities. However, as the popularity of non-Windows operating systems, particularly Linux and macOS, has grown, malware targeting these systems has also increased.

To get the most up-to-date information on the specific breakdown of viruses by operating system, I recommend referring to reputable cybersecurity reports and organizations that track malware statistics. Examples include antivirus companies, cybersecurity research firms, and governmental agencies focused on cybersecurity.
