This article was inspired by an incident in which one of my friends had a really infected computer. His computer was infected with thousands of viruses that were hiding in various files and programs. No antivirus is installed and you can not install or uninstall anything! This computer lasted more than two years in this state (!). I decided to show my dear friend how to protect her computer from hackers and other malicious threats. Now, I will share this information with you to help protect you from various Internet threats.
First, always use an anti-virus software. Even free people can meet basic security needs. Some of the free antivirus is considered better than commercial software, the fact of not getting antivirus software nowadays because expensive, is not an excuse. In fact, there is no excuse for that. If you do not have such software, you are certainly looking for problems. Most of these software have the ability to protect in real time. Enabling this feature is a necessity for maximum protection.
Getting the antivirus software and installing it is one thing and keeping it up to date is another. This should be done frequently (every day). You want your software to be updated because new threats are discovered every day and you can not be sure if you do not. Most anti-virus software can be programmed to automatically receive updates every few hours or so.
Many threats are hidden in e-mail messages. If you see an unknown email (for example, you do not know the name of the sender or you are certain that it is a spam), delete it. Do not bother to open it. In addition, do not open e-mail attachments if you are not sure about the sender. Be wary of images or files with strange extensions and names. E-mail attachments are a serious but underestimated Internet threat and should be handled accordingly.
Perform regular virus scans. Once every two or three days or maybe once a week. It does not really matter. Just do it at the right time to make sure everything is working and your computer is clean. The feeling that you feel when you discover that there is no virus in your PC is great. You feel protected.
Avoid as much as possible to use peer to peer (P2P) file sharing software. If you're careful enough, you can use P2P programs to securely download movies, songs, and software, but you can still download an infected file. For example, a song with which a keylogger is associated. This will send anything you type to another computer over the Internet. The worst thing is that you can not really know when this happens unless your antivirus software detects the recorder.
Pay attention to USB flash drives that move from one computer to another. They can be infected in different ways. So, when you connect such a flash disk to your computer, the first thing to do is to analyze it thoroughly. Chances are you find something threatening. Simply delete it or quarantine any action. Pay attention to what you are transferring from the USB flash drive to your PC.
Watch for the websites you visit. If you want to watch porn, know that you will certainly infect your computer with a virus or spyware, no matter what you do. Unless you are a security maniac and you have increased the maximum security levels via the interface of your anti-virus software. In this case, you will be informed that the page may be dangerous and contain malicious elements. You enter at your own risk.
Besides the use of anti-virus software, a good idea of security would be to use a firewall. If you are lucky, your Internet connection is already equipped with a hardware version of a firewall (common in wireless routers). Alternatively, you can download and install a version of the software. The firewall simply limits the number of ports open to the public, preventing hackers from accessing your computer.
These are just a few ideas for enhancing computer security against Internet threats such as hackers, viruses, spyware, and so on. job. You can do it. The average surfer can perform these tasks quite easily and the reward is an ultimate and complete security. Good luck!
