Definition of Antivirus

Antivirus software is a type of utility used to scan and remove viruses from your computer or smartphone. While many types of antivirus (anti-virus) programs available, the main purpose of creating antivirus is to protect computers and smartphones from viruses and remove any detected viruses.  Most of the antivirus programs have both manual and automatic scanning capabilities. Automatic scanning can check files anywhere, whether files that are downloaded from the Internet or disks that are inserted into a computer or smartphone, even files that are created by the third-party software.  Automatic scanning can also scan the entire hard drive regularly. The manual scanning option allows you to scan files one by one or the entire system whenever you want. Because of the growing technology, new viruses are constantly being made by hackers.Therefore an antivirus program must store an updated database of virus types. This database collected from the list of "virus definitions" that are referenced by antivirus software when scanning files.  Because new viruses are often distributed, it is important to always update the virus database from your antivirus software. But don’t worry, most antivirus programs automatically update the virus database every month even weeks. Basically, antivirus software is primarily designed to protect computers and smartphones against viruses. But now there are many antivirus programs that are able to protect against other types of malware, such as rootkits, adware, and spyware as well.  Antivirus software can also be reinforced with firewall features, which help prevent hackers from accessing your computer and smartphone. Utilities that have antivirus and firewall features are usually branded "Internet Security" software. In addition to antivirus, you should also understand about computer viruses. Because if you have understood the definitions, types, and examples of computer viruses, you can determine which antivirus is appropriate to ward off existing computer viruses. Most antivirus programs are available for Windows, Unix platforms, and Macintosh. But most antivirus software is made for Windows systems. This is because most hackers target viruses to computers with Windows systems.  Therefore virus protection like antivirus is very important for Windows users. If you are a Windows user, you should have at least one antivirus program installed on your computer, or your smartphone if it also uses the Windows system.  Here are a few examples of common antivirus programs, including Norton Antivirus, Kaspersky Anti-Virus, AVG Antivirus, and many more.

Types of Antivirus Anyone who finds out on the internet and then knows about various antivirus programs can benefit by allowing you to stay safe when you are online. Accessing a website can open the way for hackers to infect your computer with a virus, and they are also able to gather information or spying on you secretly.  Not only antiviruses that have various types, but computer viruses also have various types. You should also learn the types of computer viruses to know how to counteract and fix them. But you don't need to worry, by installing appropriate antivirus software, you can prevent viruses from infiltrating your computer or smartphone.

1. AVG
AVG is one of the most popular antivirus programs that can be obtained for free, and it’s easy to download directly from the internet. In addition to not taking up a significant amount of space on a hard drive, it can also work with a number of different Windows operating systems. It incorporates both antivirus and antispyware abilities and works by scanning all the files on the computer at regular intervals. Additionally, it has the ability to quarantine virus files so that they cannot do any harm before they can be checked and deleted.

2. McAfee
McAfee VirusScan has been the second most popular antivirus program on the market for years, which has enabled the company to cement its position as a strong competitor to Symantec. It provides spyware and virus protection within one program, rather than separately as many other programs do. It is necessary to take out a subscription to use McAfee, but it will give you access to continuously updating virus protection.

3. Norton
There are a number of Norton antivirus programs available, all produced by Symantec. They have quickly proven themselves to be a market leader when it comes to computer system security, with their products available from a range of different electronics supply stores. Norton programs are used by the majority of computer users on the market, who pay an annual fee for a subscription service. Norton Anti-Virus and Norton Internet Security are software programs that search the computer regularly and delete any viruses that they find.

4. Kaspersky
Russian-developed Kaspersky is not the most popular of all the antivirus protection programs; many people have probably never heard of them. However, they still provide a very effective product for protection against viruses, spyware, and Trojans. Kaspersky Internet Security and Kaspersky Antivirus prevent problems that computers will encounter in the event that they become infected.

5. Ad-Aware
This software by Lavasoft is another antivirus program that provides protection against a large number of cybersecurity threats that arise from using the Internet. They offer different levels of protection according to how much you want to spend in a one-off payment for the program. In addition to finding and removing viruses and spyware that can detect keystrokes and passwords, it will protect against Trojans. Advancements in anti-malware technology allow it to provide effective protection while not putting excessive pressure on the system in the process.

Conclusion
That's the definition and type of an antivirus. As the name implies, antivirus is created to ward off viruses. And now you know that there are many antivirus types and antivirus examples, even those that are not included in my list are still many.  

If you want to print wirelessly from your laptop, you have two basic options when it comes to installing a printer: You can either install a network printer that connects directly to your home network, or you can share a printer that is connected to another computer on your network. The option you choose will likely be dictated by the connections that your printer supports, as well as your home network setup.

Most modern printers will connect to your home's wireless network. Some network printers can only connect via Ethernet cable. Older printers or budget printers will likely need to be connected to a computer via USB and then shared on the network.

Examine your network and needs. 

Printers that are connected directly to the network can typically be easily accessed by both Windows and Mac laptops. Printers that are connected to a computer and then shared on the network are easily accessed by computers running the same operating system family, but get a little trickier when sharing across operating systems. Since it requires fairly different steps, click here for instructions on sharing a printer across operating systems.

• Installing the printer directly to the network is almost always the better choice if possible. Not only does it allow for easier connectivity, but it also means that the printer is constantly available. If you are sharing a printer that's connected to another computer, that computer will need to be turned on in order to access the printer.

Method 1: Printing to a Network Printer

1. Connect your printer to your home network. The process for this will vary from printer to printer.

• If you are connecting your printer via Ethernet, connect the Ethernet port on the printer to an open port on your router or network switch. This is typically all you'll need to do for an Ethernet printer.
• If you are connecting a wireless printer, you'll need to use the printer's display screen to connect to your wireless network. You'll need to select your wireless SSID (network name) and enter the password if it is secured. The exact process will vary depending on the printer, so refer to your documentation for exact instructions.

2. Connect to the network printer. Once the printer is installed on the network, you can connect to it from your laptop. These instructions work for all versions of Windows.

• Open the Control Panel. You can access it from the Start menu. Windows 8 users can
• Press the Win + key and type "control panel".
• Select "Devices and Printers" or "View devices and printers".
• Click Add a printer.
• Select "Add a network, wireless or Bluetooth printer". Windows 8 users will not need to select anything.
• Select your network printer from the list of available printers. Follow the prompts to install the drivers automatically. If Windows cannot find the correct drivers, you may need to download the from the printer manufacturer's support site.

3. Connect to the network printer (Mac). Once the printer is installed on the network, you can connect to it from your laptop. These instructions work for all versions of OS X. Note that the network printer must support AirPrint or Bonjour (nearly all modern network printers do).

• Click the Apple menu and select "System Preferences".
• Select the "Print & Scan" option from the System Preferences menu.
• Click and hold the "+" button at the bottom of the list of installed printers.
• Select your network printer from the list of nearby printers. If your printer isn't listed, you may need to download the software from the printer manufacturer's support site first.
• Click the Download & Install button if it appears. While OS X comes with the software for most printers already installed, your printer may require additional software from Apple. If it does, you will be prompted to download it after adding the printer.

4. Print to your newly-installed printer. Once the network printer has been added to your operating system, you can print to it just like you would if the printer was connected directly to the laptop. Open the "Print" dialog in any program and select the network printer from the list to print to it.

Method2: Sharing a Printer Between Windows Computers

1. Install the printer on the computer that will be sharing it. Since the computer will need to be on whenever you want to print, you should install it on a desktop computer that is frequently turned on.

• Most printers can be installed by simply plugging them in via USB. Refer to your printer's documentation if you are having difficulty installing the printer on the computer that will be sharing it.

2. Create HomeGroup (Windows 7 and later). If all of the computers on your network are running Windows 7 or later, you can use the HomeGroup feature to quickly and easily share your printer. If you are using Windows Vista or XP, skip down to Step 5 of this section.

• Create a HomeGroup on the computer sharing the printer. You can access the HomeGroup menu from the Control Panel. Click the Create a homegroup button to set up a new HomeGroup.
• Follow the prompts to set up the HomeGroup. When asked what you want to share, make sure that "Printers & Devices" is set to "Shared".
• Copy down the password that appears.

3. Connect to the HomeGroup on your laptop. Now that the HomeGroup has been enabled, you can connect to it on your laptop.

• Open the HomeGroup menu in the Control Panel on the laptop.
• Click the Join now button and enter the password.
• Follow the prompts to finish setting up the HomeGroup connection. You will be given the option to pick what you want to share, but this isn't necessary for connecting to the shared printer.

4.Print to the shared printer. Now that your laptop is connected to the HomeGroup, you'll be able to select the shared printer as if it was connected directly to the laptop. Make sure that the computer sharing the printer is turned on.

• Open the Print dialog in any program and select the shared printer from the list of available printers.
• If you are using HomeGroups, this is all you need to do. The next steps are for users who can't use the HomeGroup feature.

5. Enable File and Printer Sharing and then share the printer manually if you can't use HomeGroups. If either the laptop or the computer sharing the printer are running Vista or earlier, you'll have to share the printer manually.

• Open the Control Panel and select "Network and Sharing Center" or "Network and Internet" on the computer sharing the printer.
• Click the "Change advanced sharing settings" link and then expand the "Private" network settings.
• Select the "Turn on file and printer sharing" option and select Save changes.
• Return to the Control Panel and select "Devices and Printers" or "View devices and printers".
• Right-click on the printer you are sharing and select "Printer properties".
• Click the Sharing tab and check the "Share this printer" box.

6. Install the shared printer on the laptop. Now that the printer has been shared, you'll need to install the printer on your laptop so that you can select it.

• Open the Control Panel and select "Devices and Printers" or "View devices and printers".
• Click Add a printer.
• Select "Add a network, wireless or Bluetooth printer". Windows 8 users will not need to select anything.

Select your network printer from the list of available printers. Follow the prompts to install the drivers automatically. If Windows cannot find the correct drivers, you may need to download the from the printer manufacturer's support site.

Method 3: Sharing a Printer Between Mac Computers

1. Install the printer on the computer that will be sharing it. Since the computer will need to be turned on in order to access the printer, install the printer on a computer that spends a lot of time-powered on.

• When installing a printer on a Mac, you can usually just plug it in via USB and OS X will install everything automatically.

2. Enable printer sharing on the Mac that the printer is installed on. Once the printer has been installed, you'll need to enable printer sharing so that your laptop can connect to it.

• Click the Apple menu and select "System Preferences".
• Click the "Sharing" option.
• Select the "Printer Sharing" option to enable printer sharing.

3. Share the printer. Once you've enabled printer sharing, you'll want to share the printer from the same window. Check the box next to the installed printer to share it.

4. Connect to the shared printer on your Mac laptop. Now that the printer has been shared, you can connect to it from your Mac laptop.

• Click the Apple menu and select "System Preferences".
• Select the "Print & Scan" option.
• Click and hold the "+" button and select your newly-shared printer.

Click the Download & Install button if it appears. While OS X comes with the software for most printers already installed, your printer may require additional software from Apple. If it does, you will be prompted to download it after adding the printer.

5. Print to the shared printer. Once you've installed and then the shared on your laptop, you can print to it just as if it was connected directly to the laptop. Make sure that the computer that the printer is connected to is turned on.

• Open the Print dialog in any program and select the shared printer from the list of available printers.

Gaming is all about High-Quality display, vibrant colors, clear volumes, and speed. Variety is one of the biggest strengths of PC gaming. Apart from the numerous types of different hardware components, users also have the opportunity to choose which operating system suits them best. Today, there are three main choices: Windows, Linux, and macOS. However, these all cater to different audiences and have their own respective advantages and disadvantages.

1.Windows: There is no doubt that the major part of the gaming world solely belongs to Microsoft Windows. Being the most famous OS in today's world, mostly PC games are referred to as ‘Windows Games’. It’s   fun to play android game  in windows pc because of its widescreen and sound effects. Microsoft Windows is the most widespread and popular operating system. When Microsoft first released Windows 3.0 in 1990, it was considered revolutionary because of how it simplified the user interface and brought computers closer to the mainstream public

Today, we have the most advanced and most reliable version of Windows yet: Windows 10. This latest version of Windows also marks a big change in Microsoft’s approach to their flagship OS – rather than releasing a brand-new Windows version every few years, the company has decided to build and improve upon Windows 10 with numerous free updates. It is equipped with the latest DirectX software. It makes it stand alone among all other popular operating systems. This feature makes it best among all the Gaming Operating Systems.

2.Linux: Long gone are the times when gaming on Linux was next to impossible. In fact, gaming on Linux has grown quite stable in recent years. If the user wants to play games in Linux OS, they just need an app called Play on Linux. You can use Play on Linux to install other windows based .exe programs to your Linux computer. Linux is unusual in that it doesn’t denote a single operating system but rather a wide array of different operating systems all of which are based on the open-source Linux kernel. It was created in 1991 by Linus Torvalds with the idea of offering people a free and flexible OS. 

Ultimately, however, Linux is aimed more towards professional users and enthusiasts due to its powerful features, flexibility, and lower hardware requirements as compared to Windows. Playing games under Red Hat Enterprise Linux is a fun way to pass the time. Game availability depends on the variant of  Red Hat Enterprise Linux installed by the user.  That said, the interface could seldom be called “user-friendly” and Linux-compatible software is not exactly in high supply.

 3.Mac OS: The Mac is most well known for being virus-free and great for stretching your creative talents. It’s not usually known for its gaming. Due to most games being developed for the PC market games aren’t generally developed with the Mac in mind. This means that they are ported over from original PC copies. This leads to the game just having the essentials changed so it will work on Mac and ending up not being optimized to work at its best. While its roots go all the way back to 1984, macOS, as we know it today, was only released in 2001. It is second only to Windows in terms of popularity, and it differs mainly in that it is only found on Apple’s own iMac and MacBook computers.

An obvious downside to macOS is relevant to its primary advantage – the hardware. In terms of raw power, most Apple computers are sorely lacking, relying on the software for high performance instead. To put this into context, in the whole of 2017 there were over 7,000 PC games uploaded to the Steam platform.
