Clean up a malware-infected PC by deleting every trace


Our PC is infected and we do not know how to clean it up? Let's find out how to eliminate every trace of the threat.

The best weapon for the security of your computer is always prevention and in several articles we have shown you the best programs to effectively protect yourself from threats before they infect your PC.
Summing up very quickly, the main cyber threats are: viruses and malware that cause malfunctions or blockages, spyware that steal personal data or show unwanted windows, rootkits that penetrate deep into the PC by modifying and controlling it, trojans that allow you to overtake defenses and control the PC, worms that replicate indefinitely to clog memory and disk and finally ransomware, ie those viruses that block any PC activity and encrypt files asking for the payment of a ransom to free the PC, otherwise the data will be permanently lost.

Even if you protect yourself, especially those who like to experiment, we can still catch these types of malware, especially by installing little known programs and visiting unsecure internet pages.
In this guide we will look at the best free tools to use to clean up a virus-infected PC by removing all traces .

How to clean up a virus-infected PC by removing all traces

The programs that we must use to clean up an infected PC and return to use it without problems are listed below.
Just download them, install them and start the integrated scan to be able to effectively find all types of malware described above.
Cleaning with these tools is very effective but deep changes may be necessary to the system so we use them only when we have recognized all the symptoms of an infected PC (sudden slowdowns, windows that open themselves without meaning, programs that disappear, Web pages that open themselves, block screens or blackmail etc.).

1) AdwCleaner
The first program to be used to clean up a virus-infected PC is definitely AdwCleaner, which can be downloaded free of charge from AdwCleaner  website.

Once downloaded, open it and click Scan Now to start scanning all types of threats on your PC.
At the end we will be shown the malware and unwanted components found on the PC, just click on Clean and Repair to remove all traces of malware immediately.

This program is particularly effective for stopping spyware, worms, unwanted advertising windows, infected plugins, malicious extensions and any other threat that could interfere with normal Internet browsing.
Once downloaded, open it and click Scan Now to start scanning all types of threats on your PC.

At the end we will be shown the malware and unwanted components found on the PC, just click on Clean and Repair to remove all traces of malware immediately.

This program is particularly effective for stopping spyware, worms, unwanted advertising windows, infected plugins, malicious extensions and any other threat that could interfere with normal Internet browsing.

2)Kaspersky Virus Removal Tool

Another free tool that we can use to clean up an infected PC is offered by Kaspersky, a big company that deals with computer security.

We can download Kaspersky Virus Removal Tool from   Kaspersky Virus Removal Tool  website.
At the end of the download let's start and immediately click on Start scan to start the PC scan.
When the scan is finished, we remove all the threats that this tool will warn us, so that you can use the PC again without problems.

This tool is particularly effective against viruses, trojans, worms, ransomware and spyware, so we can use it without problems on all PCs that exhibit infection symptoms.

3) Spybot

Among the most effective tools to remove threats from the PC definitely stands out Spybot, which can be downloaded from Spybot

Once downloaded let's start and use the System Scan and File Scan voices , to scan all the critical areas of the system and to find the most hidden threats.

At the end of the scan confirm the cleaning to return to use the PC as before infection.
This program is particularly effective against spyware, fake antivirus programs, harmful components that open windows randomly and in general against threats that want to take control of the PC to spy on us.

4) MalwareBytes Anti-malware

One of the most famous and used tools to clean up your PC from threats is definitely MalwareBytes Anti-malware, available in free version (with trial period of 14 days) .

At the end of the installation of the program, start it and bring us to the Scan screen , where we can start the search for threats by clicking on the Scan button . 

Immediately the program will check all areas of the PC in search of the threats supported, so you can remove them automatically. 

This program is particularly effective against Trojans, worms, spyware and ransomware, so it's always good to use it when we suspect an infection.

The Premium version (with real-time control coupled with the antivirus) is offered for 14 days free; at the end of the trial period you can always use the program for manual scans but the real-time control will be deactivated until we obtain a user license. 

In our case the free version is fine so we can install it without problems.

5) HitmanPro: A very powerful program to remove threats from the PC is definitely HitmanPro, available to download from HitmanPro website.
This program has a multi-engine scanner with cloud detection system that can also catch the threats that have escaped previous tools and antivirus used.

Once started it will be sufficient to start the scan and wait; all threats will be shown in the scan summary screen ready to be deleted or moved to quarantine.

This program is particularly effective against rootkits, ransomware, trojans, spyware and tracking cookies, ie those temporary components in the browser cache that spy our activity and track us as we navigate.
The program can be used for free for 30 days without limits, after which a user license is required to be able to clean the PC (scans are always available).

So we use this HitmanPro only as a last resort when the other recommended tools have failed and the PC is still slow or infected, given its extraordinary power better to use it only when needed and when we no longer have alternatives.
