How to get rid of viruses on a PC device?

A variety of threats can get into the computer’s operating system via the Internet, from someone else’s storage medium or when installing malicious software.

Important! The development of protection systems (antivirus products) entails the “evolution” of malware. Today, they can easily “take root” in startup, reappear after futile attempts to get rid of them.

Is it possible to quickly clean the computer of viruses, because it becomes harder to secure your personal computer? But nevertheless, there are relevant methods of protection:

• The most effective, true and rude way to get rid of viruses is to reinstall the OS again. But it is worthwhile to understand that with a complete cleaning of the system from viruses, you will also lose all your data. This means that all data that was on your computer will be lost.

Important! No one cancels system backups, but then there is a risk of saving the virus along with the copied data.

• Full disk cleanup (formatting). An effective method, if there is confidence that the malicious “villain” has not settled in the system partition.
• Restore the previous state of the computer. For example, Windows can roll back to its previous state when the system was not infected with viruses. When using this function, fresh files will disappear and replaced with old ones.
• One of the surest ways is to use a proven antivirus. There are trial and free versions that every user can easily find.

How to detect viruses and prevent a threat?

There are several ways to detect malware and files:

• Pay attention to the performance of the computer. If the performance has noticeably worsened, then there is a high probability that this is precisely due to malware. Accordingly - it is time to clean the computer from viruses.
• You should also look for threats if your browser and system settings “unexpectedly” change. At the same time, work on the device is accompanied by uncharacteristic and excessive advertising, the standard search engine has changed, when you open a browser, sites unknown to you open.
• Well, one of the most effective ways is detection with an antivirus. It is not recommended to suspend the anti-virus and disable the firewall if you do not trust the software that “asks” to do such actions.

Important! Remember that if you find unwanted software, you should temporarily turn off the Internet if the problem is solved without it, because an attacker could have access to your computer.

We tidy up the RAM and the registry

Let's talk about how to monitor the RAM on a PC. If RAM is always busy with something, then it's worth seeing what exactly. You can observe this through the task manager. Directly through it, you can stop the processes that “eat” the memory. There are utilities created specifically for this. For example, Msconfig, which is also free.

Important! If after these steps the problems with RAM do not disappear, you should contact a qualified specialist.

Clear the registry is not difficult, just do all this at least once:

1. Open the “Start” panel.
2. Open the “Run”.

Computer is not trash

If your line of business does not require a “sudden” recovery of the files you just sent to the trash, then why not empty it? Let's not forget that deleted files take up space on your hard drive.

The cleaning procedure itself does not have any complexity and consists in right-clicking on the basket icon and selecting the “empty basket” item.

Important! Also, the basket itself and part of the software presented above have the function of automatic cleaning, which makes the task doubly easy.

Use of free disposable utilities

If after all the steps you couldn’t completely clean the computer from viruses, then there are antiviruses that are designed to scan your device once. Just download it and run it, and such software has several advantages over classical software:

1. It is free. The vast majority of such antiviruses do not charge money for use.
2. Easy to use. Such software has a primitive and intuitive interface.
3. Small size. Such programs "weigh" within 100 mb.

Important! Unfortunately, one-time utilities and one-time utilities cannot provide real-time protection, and it is not always convenient to download a file over and over again. We advise you to resort to this method of "treatment" only when the usual antivirus can not cope and other methods also do not help.

Top Utilities

Consider the three most popular disposable utilities:

1. Dr.Web CureIt! - convenient software, which is famous for the fact that it is impossible to "kill" during the scan. This feature makes it invulnerable to active viruses.
2. Kaspersky Virus Removal Tool. It works on the same principle.
3. ESET Online Scanner. Its feature is that it works inside the browser.
