The weakest link in the chain of computer security is the user himself. The presence of an antivirus installed on a computer does not mean the absence of malicious software on it. Hackers who develop viruses are also good psychologists. Their goal is not only to deceive the computer's security system, but also to get into the confidence of the user himself in order to penetrate his computer.
Through files downloaded from the Internet
The most common way to get viruses on a computer is via the Internet. In a desire to save money and download a paid program for free, the user visits pirated resources that offer all the most popular and necessary applications for download. On such Internet portals, it is indicated in advance that during the installation of the software, you should turn off the antivirus so that the installation goes smoothly and without problems. You should not be confident that there is no prospect of infection if the name of the downloaded file is not suspicious. It's all about the installer itself, it is into it that malicious software or ad garbage is embedded. The most harmless thing is that after installing the software, many new ones appear in the list of installed programs.
Through a USB flash drive
It happens that a virus travels from computer to computer on removable media, the owner of which does not always know about it. By saving time and skipping scanning your flash drive before using it, the risk of infecting your computer increases.
Through security holes
It is not always wise to trust trial versions of antivirus products to protect your computer. Free antivirus programs have limited functionality; they have little ability to protect your computer from viruses. Many users can legally object, saying that they have been using free antivirus for many years and the operating system runs like clockwork, pristine from viruses, as after installation. On the one hand, the rationale is correct. However, the situation itself is more like the objection of heavy smokers who smoke since childhood and still do not get cancer. It's all about the risk. If there is no important information on the hard disk of the computer, and reinstalling the operating system is not a problem for the user, then it is certainly justified. In other cases, there is simply no alternative to paid antivirus software.
Regular updating of anti-virus databases is also a guarantee of computer security. After the appearance of another virus, antivirus developers urgently release a patch for their products, designed to close security holes and respond in time to an attempt to penetrate.
Via email
You must pay close attention to all messages that come to your email address. Often, emails have attachments that contain malicious code. Before opening such messages, you need to make sure how much you know and trust the sender.
It will not be superfluous to mention that the newest and most dangerous viruses of recent years have leaked onto your computer through email attachments.
