One of the main reasons for the malfunctioning of a personal computer may be a virus in your computer. There are many possible methods of infection. A similar situation is with malware, the number of which is growing exponentially daily . Anti-virus databases are not always updated promptly, and this can lead to negative consequences. As a result, your personal computer may be affected by malware, which is almost impossible to predict.
Signs
The main sign that there is a virus in the computer is the appearance of some deviations in the work. This may be the appearance of windows that were not called by the user, and a noticeable decrease in performance, and attempts to unauthorized access to the network, and incomprehensible launch of applications in shadow mode. This is not a complete list of signs that can indicate the appearance of
malware on the system unit. At the slightest suspicion that such software is on your PC, you urgently need to take a set of measures that will help diagnose the cause of these problems.
Firewall
Experienced users recommend installing a firewall, whose name in English sounds like Firewall. It allows you to block the attempt of unauthorized access to your information. Indirectly, this will neutralize the virus that could get here. Ideally, this program should block the infection of your PC with this dangerous software. An example is the standard Windows firewall. However, often its capabilities are not enough to prevent the virus from appearing on your computer. Therefore, in most cases, specialized software is installed that has a higher level of functionality.
Antivirus
Also, to ensure the maximum level of security, it is recommended to use an antivirus. Its presence allows you to prevent infection of the machine. Even if malware appeared on your system unit, an antivirus will help to cure it. In most cases, it is enough for this program to work in active mode. With its help, you can solve the problem of how to clean your computer from viruses. To do this, it is enough to run a forced scan of the computer for the presence of various kinds of threats. It will also allow you to eliminate malware.
Utilities
If the antivirus worked, but the suspicion of the virus remained, you can resort to the help of specialized utilities. This is one of the ways
to check your computer for viruses. To do this, just download a similar program from the Internet and run it on a computer. Before downloading, it is recommended to check the utility version. It should be the latest, and the antivirus database should be the most recent. These two conditions are the key to success. Before this, you must necessarily disable the anti-virus forcibly. The operation of two products of this class on the device can lead to unpredictable consequences.
Conclusion
If there were suspicions of a virus in the computer, and after the manipulations were not obtained the desired result, it makes sense to reinstall the operating system (perhaps the problem is in it). It is also possible that a hardware malfunction occurs. In this case, it is necessary to conduct a thorough diagnosis of the system unit and try to identify the cause of the failure.
