  • Scan with Malwarebytes: The best program we can use for viruses of all kinds is Malwarebytes, a benchmark for safe malware removal for years.
  • Restart computer: after scanning and cleaning with Malwarebytes we restart the PC and enter normal mode. If there are no other symptoms of the infection we continue with the last point, otherwise we follow the advanced procedure (for professionals).
  • Clean the system of unnecessary filesSome viruses leave traces or changes on the system that must be removed to avoid future infections or problems. The best cleaning program for an infected PC is AdwCleaner, a cleaning tool to run to make the system truly safe.

After cleaning the system we enhance Windows Defender to make it very safe or install a new free and powerful antivirus like Kaspersky O Bitdefender.

If the PC is still locked or no security tool can be started due to the infection, we must use even more powerful tools to be able to clean the computer and make it operational again. The advanced procedure is available below:

  • Start your PC in safe mode: it is important to work temporarily to avoid worse damage. Before the virus blocks this mode, it is worthwhile start safe mode right away Before it’s too late.
  • Scaricare Kaspersky Virus Removal Tool: this free tool from Kaspersky analyzes your PC in depth looking for any threats, removing them effectively and quickly. It can be downloaded from the official website.
  • Use Kaspersky Anti-Ransomware Tool: another effective tool for removing the most serious threats such as ransomware e cripto-malware, the most dangerous PC viruses. It too can be downloaded from the dedicated site.
  • Use Hitman Pro: the last tool to be launched to remove all traces of viruses and malware. Equipped with a very powerful and effective cleaning engine but it is offered free for only 30 days, so it is worthwhile to launch it only if all the previous tools have failed to eliminate the infection.

After attempting the advanced cleaning we try to restart the PC and see if any symptoms of the infection still appear and if the ransomware block is gone.

If the PC does not start what to do?

If the PC does not even start in safe mode and there is no way to start the system, the only hope to recover the full operation of the computer is to use the Emergency Scan CD, i.e. optical media to boot on the internal DVD player or a external DVD player. The best emergency disks are:

  • Kaspersky Free Rescue Disk
  • Comodo Rescue Disk
  • ESET SysRescue
  • Avira Rescue System
  • Trend Micro Rescue Disk

Let’s get a blank CD or DVD, let’s go to another perfectly functional PC and burn one of the disc images above, using some burning programs; alternatively we can create the emergency disk even with a USB stick.

Once the disk or key has been prepared, connect them to the infected PC, let’s change the boot order and make sure to select the optical disc or USB stick. If we have done everything correctly, the tool’s recovery environment will start and we can immediately start a scan for malware to remove.

At the end of the scan, we restart the computer to see if it starts regularly and if it no longer shows signs of infection; it may be a good idea to take advantage of it to launch the tools seen in the previous chapters, so as to remove any residues of the infection.


After removing the malware, if we notice that Windows is behaving strangely, some items or menus are missing or some programs or apps cannot be accessed, we recommend that you reset Windows and return to initial settings, taking care to save the personal data on the PC and to use the cloud recovery procedure to immediately download the latest version of Windows during the process.
