There are various reasons why you need to use your discretion when it comes to trusting unsolicited advice and notifications from suspect programs. This is because there are so many threats posing as genuinely helpful applications as in the case of HDDoctor. The Serious System error popup is a fake alert used by HDDoctor as part of its attack on the system. Serious System is only one of the fake security alerts used by HDDoctor and is completely without basis and merit.
Users will receive the Serious System fake error pop up message if their systems are infected with HDDoctor. The fake Serious System pop up reads as follows:
Serious system error
Take note of the spelling and grammar mistakes contained in the above fake pop up message. This should already point to the legitimacy of the application and the fake alerts generated by HDDoctor. If presented with any calls to action disregard it and remove HDDoctor from your system immediately. This will also effectively annihilate Serious System error pop up message from the system and allow you to take back control of what’s rightfully yours.
Do not allow HDDoctor to run wild on your system. Remove Serious System and HDDoctor by making use of a genuine security tool which will also offer adequate future protection against similar threats and attacks.
