There are two main ways that our services and inventions have evolved over the last 100 years, either through the use of more efficient software or more powerful hardware. The easiest place to recognize this evolution is with the individual computer, where it seems every week, month, year a original piece of software or hardware someway improves the individual computing experience . This article will reveal you some clear-cut and not so clear-cut places that software and hardware have improved user experience.

Lets start off by finishing the though above about the individual computers enhancement through hardware and software. The individual computer is the manifest piece of technology that has been improved by hardware and software. foremost the software or operating systems have improved taking up less memory and other computing resources to run. Whether you are a Mac or PC zealot , we can all accept that the operating systems on both of these has seen stable improvement for quite awhile now. The browsers we exercise to surf the internet have improved as well, if you are still using an older kind of internet explorer such as IE6 you are missing out on the advancements of Fire Fox, Chrome, Safari, and even the newer versions of Internet Explorer. The hardware improvements of the individual computer authorize us to store more files and access them faster than ever before. Hard Drives are now starting to be measured by terabytes instead of gigabytes. The processors and ram that assist our computers run accelerated are also growing in speed and performance.

All of these advancements in the personal computing industry have allowed enhancement in uncountable industries, even some that you have unquestionably not even considered. For instance specific software has made it possible for flipbooks to be made of short video clips while you wait. The software, computing system, and printer permit mobile flipbook studios to be set up in about a 10-foot by 10-foot area at a party or event. Not only have the software and computer improvements made the personal computer better, they have made parties and events more entertaining. Now guests will have a memorable keepsake flipbook to take home and remember your event by.

The digital camera has also exceedingly improved thanks to the improvements to the hardware and software that they utilize . Anyone remember your first digital camera? It was unquestionably twice as big and took pictures at one-third the resolution of the current cameras on the market. Just like computers the storage space on the digital camera has improved too, now thousands of photos can be kept on your camera instead of just hundreds. Also software programs such as Apples newest version of iPhoto now utilize facial recognition to identify people in your pictures once you label them.

In addition to the digital camera software and hardware improvements have brought video to our day-to-day devices. You can now take video from a cell phone, digital camera, or if you call for the capability to take a longer video you can purchase a cell phone sized flash video cam pretty reasonable these days.

Ways to Get Rid of Computer Viruses

Computers have become indispensable part of our lives. But after computer is a machine and is prone to get damaged due to viruses or any other physical activity. We need to take care of it in order to make it functional all the time. So computer security comes into concern where ever there is internet technology. There are times when your computer tends to become slow due to virus attacks so let us understand what computer virus is? Computer viruses are malicious programs that start operating from any location of your system. Computer viruses are like biological viruses that have the tendency to replicate and spread from one work station to another placed in the same network. They are primarily responsible for sudden corruption and deletion of files. But how do you come to know that your system has been affected by virus. The signs and symptoms are quite obvious; you might face the issue of slow system, blue screen errors, abrupt reboots, frequent error messages and a large number of pop up window ads. All these indicate the possibility of virus or spyware attack. Usually there are different types of computer viruses like web bugs, Trojan horses and worms that harm your computer. They self infest in your computer without your proper knowledge and corrupt the sensitive information.

Now let us know the different methods to get rid of computer viruses with the help of computer repair experts.

Use anti spyware programs: Spyware poses a high security threat to your computer. These programs spy on your computer, steal all valuable information and even alter the configuration of your system. These are some of the signs of spyware attack like random changes in your web browser, frequent error messages, slow system and changes in search engine options.

Choose antivirus software: Generally antivirus software forms the part of your operating system as it is pre-installed. But the market offers you better choices. Some of the leading antivirus software includes programs like Norton, McAfee, AVG and Avast . Of these AVG and Avast are free downloadable software. McAfee is the oldest, Norton is the heaviest while McAfee is the sturdy retail antivirus software. Norton is one of the best antivirus software but there is only one disadvantage that installation might slowdown your system. Nowadays computer user prefer to go for AVG as it is one of the popular ones as it upgrades itself at regular intervals without prompting the user every time.

Rescue disks and online antivirus software: Like antivirus software, computer viruses also upgrade themselves. But sometimes they do allow you to access antivirus software installed in your system. Then what you should? For this you need to free online tools and few online virus scanning software to tackle these risky situations. Some of these are Avast Virus cleaner, McAfee scanner, Kaspersky online virus scanner, Trend Housecall and Panda Activescan.

You can also go for rescue disk to get rid of the above problem. If you want to install antivirus software the user has to create ‘rescue disk’ and prompt him to reboot. The rescue disks load antivirus software much before the operating system loads itself.

How does anti-virus software work?

How does anti-virus software work?
An anti-virus software program is a computer program that can be used to scan files to identify and eliminate computer viruses and other malicious software (malware).

Anti-virus software typically uses two different techniques to accomplish this:

Examining files to look for known viruses by means of a virus dictionary
Identifying suspicious behavior from any computer program which might indicate infection
Most commercial anti-virus software uses both of these approaches, with an emphasis on the virus dictionary approach.

Virus dictionary approach
In the virus dictionary approach, when the anti-virus software examines a file, it refers to a dictionary of known viruses that have been identified by the author of the anti-virus software. If a piece of code in the file matches any virus identified in the dictionary, then the anti-virus software can then either delete the file, quarantine it so that the file is inaccessible to other programs and its virus is unable to spread, or attempt to repair the file by removing the virus itself from the file.

To be successful in the medium and long term, the virus dictionary approach requires periodic online downloads of updated virus dictionary entries. As new viruses are identified “in the wild”, civically minded and technically inclined users can send their infected files to the authors of anti-virus software, who then include information about the new viruses in their dictionaries.

Dictionary-based anti-virus software typically examines files when the computer’s operating system creates, opens, and closes them; and when the files are e-mailed. In this way, a known virus can be detected immediately upon receipt. The software can also typically be scheduled to examine all files on the user’s hard disk on a regular basis.

Although the dictionary approach is considered effective, virus authors have tried to stay a step ahead of such software by writing “polymorphic viruses”, which encrypt parts of themselves or otherwise modify themselves as a method of disguise, so as to not match the virus’s signature in the dictionary.

Suspicious behavior approach
The suspicious behavior approach, by contrast, doesn’t attempt to identify known viruses, but instead monitors the behavior of all programs. If one program tries to write data to an executable program, for example, this is flagged as suspicious behavior and the user is alerted to this, and asked what to do.

Unlike the dictionary approach, the suspicious behavior approach therefore provides protection against brand-new viruses that do not yet exist in any virus dictionaries. However, it also sounds a large number of false positives, and users probably become desensitized to all the warnings. If the user clicks “Accept” on every such warning, then the anti-virus software is obviously useless to that user. This problem has especially been made worse over the past 7 years, since many more nonmalicious program designs chose to modify other .exes without regards to this false positive issue. Thus, most modern anti virus software uses this technique less and less.

Other ways to detect viruses
Some antivirus-software will try to emulate the beginning of the code of each new executable that is being executed before transferring control to the executable. If the program seems to be using self-modifying code or otherwise appears as a virus (it immeadeatly tries to find other executables), one could assume that the executable has been infected with a virus. However, this method results in a lot of false positives.

Yet another detection method is using a sandbox. A sandbox emulates the operating system and runs the executable in this simulation. After the program has terminated, the sandbox is analysed for changes which might indicate a virus. Because of performance issues this type of detection is normally only performed during on-demand scans.

Issues of concern

Macro viruses, arguably the most destructive and widespread computer viruses, could be prevented far more inexpensively and effectively, and without the need of all users to buy anti-virus software, if Microsoft would fix security flaws in Microsoft Outlook and Microsoft Office related to the execution of downloaded code and to the ability of document macros to spread and wreak havoc.

User education is as important as anti-virus software; simply training users in safe computing practices, such as not downloading and executing unknown programs from the Internet, would slow the spread of viruses, without the need of anti-virus software.

Computer users should not always run with administrator access to their own machine. If they would simply run in user mode then some types of viruses would not be able to spread.

The dictionary approach to detecting viruses is often insufficient due to the continual creation of new viruses, yet the suspicious behavior approach is ineffective due to the false positive problem; hence, the current understanding of anti-virus software will never conquer computer viruses.

There are various methods of encrypting and packing malicious software which will make even well-known viruses undetectable to anti-virus software. Detecting these “camouflaged” viruses requires a powerful unpacking engine, which can decrypt the files before examining them. Unfortunately, many popular anti-virus programs do not have this and thus are often unable to detect encrypted viruses.

Companies that sell anti-virus software seem to have a financial incentive for viruses to be written and to spread, and for the public to panic over the threat.
