TO PROTECT OUR COMPUTER FROM VIRUSES


           
Every day we are facing with many computer problems. Virus is a common word in our everyday life. It harms us by destructing our important work. And now we will discuss about the way of rescue from Virus.  The steps of protecting computer are given below:

  • Installing an antivirus program and keeping it up-to-date can help defend your computer against viruses. Antivirus programs scan for viruses trying to get into your email, operating system or files. New viruses can appear daily so check the manufacturer's website frequently for updates. Some antivirus programs are sold with annual subscriptions that can be renewed as needed but many are also available for free. Microsoft offers Microsoft essentials, a free antivirus program you can download from the Microsoft Security Essentials website. You can also visit the windows security software provider's webpage to find a third-party antivirus program.
  • Don't open email messages from unfamiliar senders or email attachments that you don't recognize. Many viruses are attached to email messages and will spread as soon as you open the email attachment. It's better not to open any attachment unless it is something you are expecting.
  • Use a pop-up blocker with your browser. Pop-up windows are small browser windows that appear on top of the website you are viewing. Although most are created by advertisers, they can also contain malicious or unsafe code. A pop-up blocker can prevent some or all of these windows from appearing. The pop-up blocker feature in Internet Explorer is turned on by default.
  • Keep windows updated. Periodically, Microsoft releases special security updates that can help protect your computer. These updates can help prevent viruses and other computer attacks by closing possible security holes.
  • Use a firewall. Windows Firewall or any other firewall program can help alert you to suspicious activity if a virus or worm attempts to connect to your computer. It can also block viruses, worms and hackers from attempting to download potentially harmful programs to your computer.
  • Use your browser's privacy settings. Being aware of how websites might use your private information is important to help prevent targeted advertising, fraud and identity theft. If you are using Internet Explorer you can adjust your privacy settings or restore the default settings whenever you want.
  • Turn on User Account Control (UAC). When changes are going to be made to your computer that require administrator level permission, UAC notifies you and gives you the opportunity to approve the change. UAC can help keep viruses from making unwanted change.
  • Clear your Internet cache and your browsing history. Most browsers store information about the websites you visit and information that websites might ask you to provide such as your name and address. While it can be helpful to have these details stored on your computer, there are times when you might want to delete some or all of them. For example, when you are using a public computer and don't want to leave personal information behind.



MAXIMIZING THE SPEED OF INTERNET CONNECTION



The steps of maximizing the speed of internet are given below:


·       Firstly, you have to check to see if faster internet connections are in your area. Fiber optic and cable internet tend to be faster than DSL and Dial-up.
·       Secondly, you need to do some arrange on your PC. Run Disk Defrag, a scan disk, a Virus scan, a malware scan and clear your recycle bin. An unusually slow Internet connection experience is often the only the sign that your computer is infected with Viruses or other malware. Delete old files and temporary files. Never allow the free space on your C: Drive to be less than 10% of the total size or twice the installed RAM. Google or your local computer repair store should be able to help you with this if you don’t know how or you can use any good system cleaner and PC optimizer tool for free or purchase something.
·       Thirdly, you better reset your home network. Sometimes restarting your home net work or your router will increase the speed of connection.
·       If you have multiple computers sharing a connection, make sure all the computers are physically connected to a router or switch and not just to a hub. Hubs are “DUMB” low-level equipment while routers are capable of prioritizing and directing traffic effectively.
·       Now optimize your cache or temporary internet files. These files improve your internet connection performance by not downloading the same file over and over. When a web site puts their logo graphic on every page your computer only downloads a new one when it changes. You should be aware about that if you delete the temporary files they must be downloaded again when you go to that site. If you disable the cache then it must be downloaded every time you view the page that uses it. This can be fixed by opening internet Explorer, clicking on Tools at the top and closing “internet options”.
·       If you are using a wireless router, make sure it doesn’t conflict with a cordless phone or wireless camera. Wireless routers come in three varieties; 802.11 b.g. and n(2.4Ghz) or 802 a (5.8Ghz). If you are using a 2.4Ghz cordless phone and 2.4Ghz wireless router then your internet connection speed will slow while you use the cordless phone. The same is true of wireless security cameras. Check on your phone and camera, if it’s 900 MHz, then its fine. If it says 2.4Ghz or 5.8Ghz then it could be the cause of your slow connection speed while they are in use.
·       You better to call internet service provider. Sometimes you just have bad service. They can usually tell if your connection is substandard without having a technician come to your home.
·       If your computer is slow then upgrade your computer.
·       Upgrade your router specifically look into any speed specifications. Older routers may be not capable of transmitting to/from the internet faster than 10 Mbps. Also older routers may be underpowered so that even though the theoretical speed is 10 mbps the processor on the router is too weak to reach maximum speed.
·       You should upgrade your router firmware. Check the manufacturer’s web site for firmware downloads for your router. Compare this with your version and upgrade if necessary. Most routers have web interfaces for managing this, check for any labels on your router specifying default address, username and password.
·       You can replace your old cable modem. Any solid state electronics will degrade over time due to accumulated heat damage. Your broadband modem will have a harder and harder time concentrating on maintaining a good connection as it gets older. An after –market cable modem as opposed to a cable-company modem will frequently offer a better connection.
·       Sometimes your connection might be slow because other programs are using it. To test if other programs such as anti-virus and other updates are accessing the internet without you know.
