Sharing one of the antivirus software:
Kaspersky Lab is an international group that employs over 2,000 highly qualified specialists, has central offices in Moscow, as well as regional headquarters overseeing the activities of local representatives and partners in five global regions: Western Europe; Eastern Europe, the Middle East and Africa; North and South America; the Asia-Pacific region; and Japan. The company currently works in more than 100 countries across the globe and has its own territory offices in 29 countries. The company’s products and technologies provide protection for over 300 million users worldwide.
The group’s main decision-making body is the Board of Directors, responsible for setting out an overall development strategy and appointing senior management figures.
Over 300 million people worldwide are protected by Kaspersky Lab products and technologies. Kaspersky Lab’s corporate client-base exceeds 200,000 companies located around the globe, ranging from small and medium-sized businesses, all the way up to large governmental and commercial organizations.
They believe that everyone should be free to get the most from technology – without intrusion or other security worries. Their crack team of specialists gives us the freedom to live our digital life without worrying about our personal information and assets.
For 13 years, their team of experts has worked on exposing, analyzing and neutralizing IT threats. Along the way, they have amassed a tremendous amount of experience and knowledge about malware and how to deal with it. Today, Kaspersky Lab is firmly positioned as one of the world’s top four leading IT security software vendors for endpoint users (according to IDC).

HISTORY OF ANTIVIRUS
Most of the computer viruses written in the early and mid 1980s were limited to self-reproduction and had no specific damage routine built into the code.[2] That changed when more and more programmers became acquainted with virus programming and created viruses that manipulated or even destroyed data on infected computers.
There are competing claims for the innovator of the first antivirus product. Possibly the first publicly documented removal of a computer virus in the wild was performed by Bernd Fix in 1987.[3][4]
Fred Cohen, who published one of the first academic papers on computer viruses in 1984,[5] began to develop strategies for antivirus software in 1988[6] that were picked up and continued by later antivirus software developers.
Also in 1988 a mailing list named VIRUS-L[7] was started on theBITNET/EARN network where new viruses and the possibilities of detecting and eliminating viruses were discussed. Some members of this mailing list like John McAfee or Eugene Kaspersky later founded software companies that developed and sold commercial antivirus software.
Before internet connectivity was widespread, viruses were typically spread by infected floppy disks. Antivirus software came into use, but was updated relatively infrequently. During this time, virus checkers essentially had to check executable files and the boot sectors of floppy disks and hard disks. However, as internet usage became common, viruses began to spread online.[8]
Over the years it has become necessary for antivirus software to check an increasing variety of files, rather than just executables, for several reasons:
- Powerful macros used in word processor applications, such asMicrosoft Word, presented a risk. Virus writers could use the macros to write viruses embedded within documents. This meant that computers could now also be at risk from infection by opening documents with hidden attached macros.[9]
- Later email programs, in particular Microsoft's Outlook Expressand Outlook, were vulnerable to viruses embedded in the email body itself. A user's computer could be infected by just opening or previewing a message.[10]
As always-on broadband connections became the norm, and more and more viruses were released, it became essential to update virus checkers more and more frequently. Even then, a new zero-day virus could become widespread before antivirus companies released an update to protect against it.

UTILITIES
Utility software is a kind of system software designed to help analyze, configure, optimize and maintain the computer. A single piece of utility software is usually called a utility or tool. Ideally, microcomputer would continuously run without problems. But, everything can happen such as computer can freeze up, operations can slow down and so on. So, utility software is designed to make computing easier.
Utility software should be contrasted with application software, which allows users to do things like creating text documents, playing games, listening to music or surfing the web. Rather than providing these kinds of user-oriented or output-oriented functionality, utility software usually focuses on how the computer infrastructure (including the computer hardware, operating system,application software and data storage) operates. Due to this focus, utilities are often rather technical and targeted at people with an advanced level of computer knowledge.
There are hundreds of different utility program. Most utilities are highly specialized and designed to perform only a single task or a small range of tasks. However, there are also some utility suites that combine several features in one piece of software.
