Windows Activation Pro virus removal guide

What is Windows Activation Pro?

Windows Activation Pro is a malware (scam), which locks victims' computers and then displays a window stating that malicious software has been detected and that the victim must enter a valid Windows Activation Key. It is also stated that the victim may call Customer Support via a telephone number provided (1-844-459-8882) to receive help in solving this problem.

Windows Activation Pro scam

After system infiltration, Windows Activation Pro modifies various settings allowing it to display a fake BSOD (Blue Screen Of Death) stating that the Windows copy has expired. Entering an Activation Key, however, does not remove the lock. Therefore, users have no choice but to call the aforementioned Customer Support number. Be aware that the persons behind this telephone number are cyber criminals who attempt to sell unnecessary support services. They will ask victims to make certain payments in exchange for a valid Product Key, which will supposedly remove the lock. This behavior is common to various ransomware-type viruses. We strongly advise you not to call the telephone number or pay the ransom. The developers of the 'Windows Activation Pro' scam aim to generate as much revenue as possible by attempting to trick you into paying, and then ignoring you. Furthermore, they might steal your credit card information, which can lead to serious privacy issues or even identity theft.

Although Windows Activation Pro scam does not encrypt system files, it shares many similarities with other ransomware-type viruses. Examples include Bloccato, Locky, CryptoHitman, and Cerber. All infiltrate the computer, encrypt files, and demand a ransom. The only differences are size of ransom and type of algorithm used to encrypt the files. Research shows that most viruses are distributed via infectious email attachments, peer-to-peer (P2P) networks, fake software updates, and/or trojans. Therefore, be cautious when opening attachments sent from unrecognized/suspicious email addresses and when downloading files/software from third party sources. Keeping all installed applications up-to-date and using a legitimate anti-spyware or anti-virus suite is also paramount.
