Persistent Screen problem, BIOS malware
« on: July 28, 2019, 12:51:44 PM »
Hi, I have a persistent problem because of a screen deformation of clarity that remain even when I reformat entirely the partition of the system for a new installation and that is shown also from the bios side. Some months before the screen was clean but the problem started gradually from a little part until it cover nearly all the surface of the screen. I joint the screen photo. Thank You for the help!.

Unfortunately from the screenshot and your notes this looks very much like hardware failure rather than software.

It seems to be either the screen, inverter or graphics chip.

Hi Nordine,

I think it doesn't seem to be caused only by CIS. Please check whether the screen problem occurs only when CIS is enabled, if so kindly share us the CIS version and windows version.  :-TU

If the screen looks the same when the BIOS is loaded we are looking at a hardware issue. Then it is not a virus.

This has not relation at all to CIS as it had been existing already before its installation.
I suppose it is a malware that reside in the BIOS interface of the computer and it can not be a hardware deficiency because the effect of light is constantly changing it began only with light then it added darkness.

This is 99.9999% a hardware issue. Is your laptop still under warranty? If it is please invoke the warranty with its vendor.

Thank you for the advice but this just mean there is no solution for the BIOS infections, however it is also the opinion of the manufacturer community. But still I have the impression it is not a hardware physical problematic of the pc.

BIOS viruses are very rare and the symptoms I see are very very likely, 99.99999%, a hardware issues.

To rule out it is a BIOS virus flash the BIOS. If the graphical glitches still appear directly after flashing when your system first enters the BIOS after the mandatory then you know it is a hardware issue.

Hello again, I had searched for a solution to flash the Bios and theoretically I had found the answer at the manufacturer website which consist just of the keyboard uses but the problem the keys combination had not worked for me, so I have not a solution to initialize the BIOS to its default state, farther that I can see the malware program when it start.

Now I just update the BIOS using a download but actually this do not resolve the problem and the screen remain perverted by the effects of lights and shades.

This proves you have a hardware issue. This is not a virus. If the system is still under warranty please invoke the warranty or have a person knowledgeable look at the system.

Is this a laptop or a desktop computer? If it is a system with an onboard graphics solution then the solution might be to buy a new one. Although I have seen people on youtube do funky things with certain on board NVIDIA chips but that is only for advanced users and after making back up of data etc.

EricJH is most likely right.

It has the clear signs of a faulty display.

Your HP laptop has a faulty (broken) display panel. Most likely it has been sat on, leant on or trodden near the bottom left corner (where the darkest area of the deformation is).

This is not a virus, BIOS or otherwise.

I've never seen a laptop screen do this spontaneously or have it caused by software (malware or otherwise)- LED and LCD screens simply do not malfunction in this manner. This is simply a screen that has been physically damaged.

Sorry to be the bearer of bad news.
