How to remove malware from your PC

Virus, malware and spyware are often manifested in different ways, from the most dangerous that can get to delete information from our computer to those who send this information to other computers to steal important data, to others that simply show us on screen a window that informs us that we are infected, and we must pay to register and be able to use a hypothetical program, which promises that it will be cleaned and solved.

What do you do if a virus or malware has infected your computer?

It is at that moment when we feel like taking a good hammer and hammering us with the PC. But it’;s going to be more expensive, so we’;re going to effectively eliminate the problem. Before starting, we will make a backup of our data, whether they are “;my documents, images, videos”; and everything we have in our user profile, which is the one that will be eliminated. Once the copy of our files is done on an external hard drive or USB memory, we start with the procedure of virus, malware or spyware.

Prepare disinfection

The first thing you must do is download and install the programs that you will need, either from the device itself or through an external device through a USB drive. Plus précisément, the software that you will need is:

  • GridinSoft Antimalware – Currently the best disinfection tool you can find and in whose free version are all the utilities that you need.
  • CCleaner – For your purposes, it is perfect when it comes to cleaning the registry of wrong keys and other traces after the battle.

It may be a good idea to disconnect the Internet connection during the process, but before doing so, it is recommended to run GridinSoft Anti-Malware to update the virus definitions database to the most up-to-date version. A few seconds after opening, a pop-up window will appear that will suggest you install the most updated version of the application. As for the database, by clicking on the Run Update button of the Update Menu tab, you will update it. The analysis itself you leave for later.

Stop malicious processes

You are already in safe mode. If you have not done so, disable your WiFi or cable connection to narrow the problem. You are going to start ruling out problems. Yоu start RKіll tо stop аll resident рrосеѕѕеѕ аnd рrеvеnt them frоm bесоmіng invisible to the аntіvіruѕ or dіrесtlу preventing thеm frоm bооtіng. Then click on the executable and in a symbol window, you will see the result of the analysis.

The next step is to check if you have installed anything that may be infected. Pour ce faire, go to the Add or Remove Windows Programs section or, better yet, open CCleaner and check it in the Tools>; Installed Programs section. Organize all the installed programs by date and check the latest ones. Eliminate everything that you consider suspicious, and that coincides with the present day. Since you are in CCleaner, it is also a good idea to go to Tools>; Home and take a look.

Proceed with disinfection

Open Anti-Malware and wait. The quick scan will start automatically. Après analyse, you will see the report with the detected elements. Mark them all and give the bottom button Delete Selected. If it asks you to restart, do postpone it, because there are still things to do.

In the case of disinfection tools, it is always good to resort to more than one tool (eye, malware detectors, not antivirus with resident protection, since the latter usually cause conflicts between them if they are installed together). You have buils-in Windows Defender.

Before proceeding to the restart, it is a good idea to take a look at the browser, since it was probably the gateway to the infection. Each case is a world, but a common resolution is to reset the browser to its factory state to reverse a possible installation of a malicious extension or any change in the default home page.

Check that you are clean

Are you safe now? You had an antivirus installed or not; you can use GridinSoft Anti-Malware to check it since it is a useful online analysis tool that during the installation process updates the database and performs the scanning.

Clean the remains

It only remains to leave everything as it was. For this, the tool of registry cleaning and elimination of temporary files of CCleaner comes to us of pearls.

In the case of rebel malware

If some viruses or other infections resist being eliminated or reappear at the time of scanning the system, apply the following method:

  • Identify, if possible, the true name of the malicious file and delete it manually in safe mode.
  • Uncheck the Windows XP Automatic Restore (this is in the Control Panel / Performance and Maintenance / System menu.) On the Restore tab, the system check box deactivates the system restore; this will allow you to eliminate all the system restore points.
  • Once this is done, restart the computer in safe mode (press the F8 or F5 key (if F8 does not work) during startup) then use the arrow keys to select the safe mode.
  • After restarting Windows in safe mode, scan the computer with the selected antivirus, in the same way for anti-spyware and other utilities, to permanently eliminate the intruders. If there is a need, remove the malware you wrote down previously, from the directories or folders indicated by your security programs.
  • Empty the recycle bin, temporary files, etc.. with CCleaner or another that fulfills the same function.
  • Replace the desired Internet Explorer home page, click on Start, Panneau de commande, and Internet Options and the General tab, fill in the homepage. Once finished, restart the computer normally.
