To use the computer safely, it is essential to know about computer security.
Please be sure to check the following seven contents.
Sometimes bugs are found in operating systems or other software after they are released. When there are security-related bugs which are called “security holes”, there is a possibility of viruses or malicious users gaining entrance to a computer’s system. In general, when a security hole is found, the software’s manufacturer will release a program to fix it. Therefore, it is recommended that you use software’s latest versions through regular updates.
Viruses are illegal programs that infect and cause damage to computers. There are various ways viruses can infect and damage computers, but in general, computers become infected when users open attachments to suspicious emails or browse questionable websites when the computer has a security hole.
When a computer becomes infected with a virus, its operations can become unstable, files can become damaged,strange messages can appear on screen, and other various symptoms can occur. Other viruses can infect computers and present no noticeable symptoms, but find files and users’ personal information and transmit them over the Internet.
Therefore, it is vital to install anti-virus software and periodically scan your computer to check whether it has been infected with a virus or not.
Anti-virus software releases(almost daily) “pattern files” for identifying viruses so that the software is able to protect computers from the latest types of viruses. If pattern files are old, then the software is unable to identify new types of viruses. Do not forget to update these files.
There are also types of anti-virus software that can be used free of charge, such as Microsoft SecurityEssentials. These types of software, basically, are to be used at the user’sown discretion. Therefore, users should be fully aware that their manufacturers offer no guarantees that their software will not cause a computer to malfunction.
Scanning computers for viruses should be done at least once a month, or, if possible, once a week.
If you use Windows, your OS comes with the firewall function switched on. If you use a Mac, firewall settings can be somewhat complicated. Simply switching on the firewall on a Mac can sometimes affect how other applications operate.Please refer to the following website when adjusting your firewall settings.
Backing up your computer regularly can protect you from the unexpected such as hardware failures and computer virus infections.
*Computers can often become broken without doing or touching anything. Since it is not unusual for a computer to become broken without warning, in particular with older computers, it is important to back up your computer and not simply assume your computer will not have any problems.
When using the Internet, there are many times when you use passwords. They serve an important role in verifying that users are who they say they are. When passwords become known to others, it is possible for them read your email, use your social networking accounts, etc. Never tell others what your passwords are and closely manage your passwords with the following in mind.
Microsoft offers a website that will test the strength of your passwords.
Change the password, if the website says it is “weak.”
Email is an important way to exchange information on the Internet. It is something many people use every day. However, viruses can sometimes be sent as email attachments and emails can also take users to phishing sites that seek to trick users into revealing their personal information.
There are many online services where users can easily enter information such as product reviews and comments on bulletin boards and blogs. Some of these have URLs entered that may take users to sites for phishing scams or where viruses can infect users’ computers. This can be especially prevalent on sites where postings can be made anonymously and without registration. Therefore, be careful about clicking through to sites with links on such pages.
