“High Priority Message” virus. How to remove? (Uninstall guide)
“High Priority Message” scam wants to trick unsuspecting computer users into calling fraudsters and wasting money on their services
“High Priority Message” alert is a deceptive pop-up that appears on the screen after visiting a phishing website. Such visits might occur due to adware existence on the computer but can also occur after clicking on a malicious online ad[1]. These scam pop-ups say “Do not ignore this high priority message” and repeatedly urge the victim to call a provided “toll-free” number.
It has been noticed that the deceptive tech support scam message comes from Criticalwarningerrortgfn.xyz domain; however, pop-ups displaying similar fake security warnings can be opened by a variety of different scam pages available today.[2] If you noticed a similar warning on your screen, close the browser and check your computer for adware/spyware installed on it. You can use Reimage software to scan the computer if you want.
The website behind the “High Priority Message” pop-up says:
A problem has been detected and windows has been shutdown.
DRIVER_IRQL_NOT_LESSOR_EQUAL
If this is first time you’ve seen this screen, contact windows technician: 1-800158-029
Beginning dump of physical memory.
Immediately contact technical support to prevent further damage
A problem has been detected, and Windows has been crash
The rest of the message says that “the problem seems to be caused by the following file: SPCMDCON.SYS” and informs about “PAGE_FAULT_IN_NONPAGED_AREA” issue. However, these issues are invented and do not even exist on your PC. Therefore, you must find and remove “High Priority Message” malware that is trying to convince you to contact tech support scammers.
It is hard to identify which program is causing these deceptive pop-ups, so we recommend using anti-malware software for identification and “High Priority Message” removal. If you haven’t decided what security program you want to use, consider relying on software suggested by our and Zondervirus.nl[3] teams: Reimage, Malwarebytes MalwarebytesCombo Cleaner or Plumbytes Anti-MalwareMalwarebytes Malwarebytes.
