How to prevent computer viruses are not affected

Some things to keep the virus from infecting and spreading to the computer are as follows:

1. Using antivirus software is always updated regularly. Do it updates automatically if the computer is connected to the Internet or manually by downloading the file to be installed antivirus updates later. It aims to identify and eradicate the virus can be new viruses that keep popping up. This becomes important if a computer user always use flash or other device that is always moving a computer or frequently used on the internet which will likely bring new viruses that can be transmitted to the computer. Or if the computer is always used for the Internet. Updates can be done every 1 or 2 weeks, but this depends also from the antivirus update service providers.
2. For computers connected to the network, always use a firewall to prevent viruses and other disorders such as hackers and so forth.
   
3. Perform a virus scan on the flash or external hard drive into a computer that was previously used on another computer. This becomes especially important for computer users who use portable antivirus (not necessarily direct the installation and use).
4. Do not open or execute files from another computer for suspicious, such as files or folders that berekteksi *. exe (application) that looks suspicious.
