HOW TO KNOW IF A WINDOWS COMPUTER IS INFECTED WITH A VIRUS


It is not always possible to detect the appearance of malicious code on a Windows computer before they have caused any harm to the system. In addition, different viruses manifest themselves in their own way, and they have no common features. However, a PC user should still pay attention to various manifestations of malware actions. Firstly, in order to avoid personal information falling into the wrong hands, and secondly, so that you do not have to reinstall the system again .


CPU AND MEMORY LOAD

The most serious load on the computer, or rather its processor and memory, miner viruses. Because of them, almost all PC resources are spent on cryptocurrency mining, while other programs and system processes start to run slower. You can make sure that such a "miner" or virus has got on your computer using the Task Manager. Having opened it, it is worth checking if some process is taking too much RAM. If the answer is yes, it could be malicious code.


On the other hand, the reasons for freezing programs are often different - not related to any viruses. Sometimes it's just a lack of RAM when trying to run software or a game with high demands on a not-too-powerful computer. The speed can also slow down in cases where there is almost no free space on the system disk. Windows updates that are not installed on time may be the cause of the problem.


THE APPEARANCE OF ADVERTISING AND SPAM

The list of signs of a computer virus infection is the appearance of a large number of advertisements when using a browser. The malicious code replaces links to almost all sites with its links. Basically, this is an advertisement for casinos, bookmakers and resources for adults.


The user can learn about viruses on the PC and by the fact that spam starts to be sent on his behalf. First of all, by email. Letters can also cause problems - but not for the owner of the computer, but for the addressees of his letters.


NEW SOFTWARE AND DISABLED ANTIVIRUS

Due to the appearance of some types of viruses, third-party software may spontaneously install on your computer. You can find out about this by looking at the list of installed programs and components. And also - by new icons on the desktop or on the taskbar.


Often, malicious code affects the operation of the antivirus. Virus programs can interfere with running system scans. Or even stop your antivirus software. In extreme cases, the shortcuts that launched the antivirus can disappear completely.


PROBLEMS WITH INTERNET ACCESS AND DATA LOSS

The user can notice the infection of the computer with a virus by completely stopping access to the Network or by a serious decrease in speed. There can be two reasons - the virus sends information from the PC to outsiders or some data is downloaded from the Internet. However, the access speed may decrease for other reasons, for example, due to the fault of the provider.


Lost data can be a symptom. And, while it is almost impossible to notice the theft of passwords, the disappearance of files is detected much easier and faster. There are viruses that can steal not just data, but funds from electronic wallets - and even from bank accounts. It is also not difficult to notice such a loss - although it is hardly possible to return the funds back.


PROBLEM SOLVING

Problem solving methods are standard for dealing with malicious code. The first thing a user needs to do is run an antivirus program that will scan the system and destroy (or try) viruses. This is followed by the installation of all the necessary updates of the operating system - some of them can close the vulnerabilities of Windows. It is also worth using utilities for cleaning and optimizing the registry. But as a last resort, when the malicious code could not be removed, you can try or reinstall the system - or contact a specialist.
