Antivirus-Program

No matter how a home computer is connected to the Internet, intruders attacks are often successful. Many home computer owners don’t realize that they need to pay attention to computer security. In the same way that you are responsible for having insurance when you drive a car, you need to also be responsible for your home computer’s security. We will explain how some parts of the Internet work and then describes tasks you can do to improve the security of your home computer system. The goal is to keep intruders and their programs off your computer.

Although there is no guarantee that you’ll always be free from spyware, there are some things you can do to seriously lower your risk. First and foremost, you need to use an antivirus program that detects and prevents spyware from installing itself on your computer (and removes it). Antivirus software can also periodically scan your computer for spyware that may get through and remove it.

Nobody is immune from catching a computer virus, becoming victim to a phishing scam, or being the target of a clever piece of spyware unless one practices technology or computing abstinence. You can significantly lower your risk by taking some precautions.

Anti-virus software protects your computer from viruses that can destroy your data, slow your computer's performance, cause a crash, or even allow spammers to send email through your account. It works by scanning your computer and your incoming email for viruses, and then deleting them.

Symptoms of a computer virus:

If you suspect or confirm that your computer is infected with a virus, obtain the current antivirus software. The following are some primary indicators that a computer may be infected:

  • The computer runs slower than usual.
  • The computer stops responding, or it locks up frequently.
  • The computer crashes, and then it restarts every few minutes.
  • The computer restarts on its own. Additionally, the computer does not run as usual.
  • Applications on the computer do not work correctly.
  • You see unusual error messages.
  • You see distorted menus and dialog boxes.
  • There is a double extension on an attachment that you recently opened, such as a .jpg, .vbs, .gif, or .exe. extension.
  • An antivirus program is disabled for no reason. Additionally, the antivirus program cannot be restarted.
  • An antivirus program cannot be installed on the computer, or the antivirus program will not run.
  • New icons appear on the desktop that you did not put there, or the icons are not associated with any recently installed programs.
  • Strange sounds or music plays from the speakers unexpectedly.
  • Slow internet connection.
  • Changing your web browser’s home page.
  • Loss of internet connectivity.
  • Unable to visit specific websites, which may include redirecting you to another one.
  • A program disappears from the computer even though you did not intentionally remove the program.
Note: These are common signs of infection. However, these signs may also be caused by hardware or software problems that have nothing to do with a computer virus. Unless you run the Scan using any Antivirus Program, and then you install industry-standard, up-to-date antivirus software on your computer, you cannot be certain whether a computer is infected with a computer virus or not.

Keep your Security Software to update itself automatically:

Keep your security software active and current: at a minimum, your computer should have anti-virus and anti-spyware software, and a firewall. You can buy stand-alone programs for each element or a security suite that includes these programs from a variety of sources, including Commercial Vendors or from your Internet Service Provider. Security software that comes pre-installed on a computer generally works for a short time unless you pay a subscription fee to keep it in effect. In any case, security software protects against the newest threats only if it is up-to-date. That's why it is critical to set your security software to update automatically.

Once you confirm that your security software is up-to-date, run it to scan your computer for viruses and spyware. If the program identifies a file as a problem, delete it.

Also, some software applications have default settings that allow other users to access your computer unless you change the settings to be more secure. Examples include chat programs that let outsiders execute commands on your computer or web browsers that could allow someone to place harmful programs on your computer that run when you click on them. 

Note: Spyware applications are typically bundled as a hidden component of freeware or shareware programs that can be downloaded from the Internet; however, it should be noted that the majority of shareware and freeware applications do not come with spyware. So, spyware is similar to a Trojan horse in that users unwittingly install the product when they install something else.

Some scam artists distribute malware disguised as anti-spyware software. Resist buying software in response to unexpected pop-up messages or emails, especially ads that claim to have scanned your computer and detected malware. That's a tactic scammers have used to spread malware.
