Acer Packard Bell Startup

Some details:
Is your PC back from the service center? Has it 'undergone' a system reinstall? Who knows, it might not even be yours! (Well, the hardware is yours, but not the 'software' system)

Explanations:
Understand that ACER and Packard Bell are PC assemblers. Of all the components that make up the PC (power supply, motherboard, memory sticks, hard drive, monitor, keyboard, and mouse...), Packard Bell only designed the case, the chassis, the tower. Just this large piece of metal and plastic/metal panels with the brand symbol engraved/bent on it.
I myself, like many others, have assembled my own PC. If you ask me for the brand, I won't give you less than 6! Intel for the processor, eVGA for the motherboard, ASUS for the graphics card, Cooler Master for the power supply, GSkill for the memory, Seagate for the hard drives, Corsair for the tower... Logitech for the keyboard)

Solution:
Reinstall your system with the CD that was provided to you with the equipment.

Because the manuals don't tell everything... But not nothing either, right!

Hello Erwan, and thank you for your attention.

My computer hasn't returned from the repair service; I've had it for 3 years, and it's not a laptop.

However, on Friday, I noticed that a small unknown icon appeared at the bottom like a tower with a minus sign on it that was moving and then disappeared after a long time. When I clicked on it, it said that new software was being installed, which was not the case.
All my files and software are there, except for one for photo editing, which I had to reactivate with an installation key provided when purchased, as if I just bought it.

I don't really want to format it if it's not necessary.

Could this be a remote update by Packard Bell?
Or someone else?

It's strange to see Acer when I turn on the computer...

Thanks in advance for your help.

Erwan, here are the answers to your questions
The icon was on the taskbar at the bottom of the screen
It appeared suddenly and it surprised me when I clicked on it; it said a software was being installed even though I wasn't installing anything. I couldn't remove or close it.
My daughter was on Facebook shortly before, as she is every day.

After this icon, I noticed that the settings had changed, as well as the screen resolution. I had to reset everything back to how it was before, icon size, display size. But everything is still there, including the photo software site mentioned earlier.
My antivirus is Avira Free and Microsoft Security Essential

I confirm I had Packard Bell when starting up (my daughter confirmed this to me) as the name of my PC tower and now it says Acer when starting up.

In general system information: manufacturer = Packard Bell
I also thought someone might have logged into my computer; is it possible to check it that way?

Thanks for your help...

I have a Packard Bell for which I took the latest updates recently
and didn't see any Acer on the horizon.

And what if I did a restore to a date from last week?
Thank you..

Yes, you can try it, but I'm not sure it will end.

In trying to restore to last week, I went to accessories, system information, and there it says Acer as the manufacturer, whereas in general system information it clearly states Packard Bell.
I don't understand anything at all, why Acer is there and why it changed by itself??..........

Thanks to anyone who can help me understand, and especially if I need to reformat the PC; I'll try restoring to an earlier date first, and I'll keep you posted.

Here is additional information that might help you

I restored to an earlier date last week and now it brings back the icon at the bottom on the taskbar (it's actually a tower or PC, I'm not sure of the exact term with a green ball that goes up and down)

it's been more than 2 hours - "INSTALLING DEVICE DRIVER SOFTWARE"
(everything is lagging during this time)

clicking on it opens a window and here are some lines:
Intel 82801 244E Bridge....................................................Ready to use

and others..........

and this morning still Acer with
a window that opens on the taskbar and indicates: USB ADSL Loader
and Avira: 2 new files installed

Never in 3 years has it done this to me.

Thank you for helping me understand all this, what should I do? Should I be worried?

In my opinion, it's a big virus that must be causing this!
Backup your main documents and format
that's what I would do
it's already happened to an internet user here

Thank you, Christian, that's what I'm going to do then... damn

How could I be infected despite my antivirus?

Also, how do you explain that I have "Packard Bell" in "general system" and "Acer" in "system tools", could the virus have changed that?

There's something that comes back to me from an email I received last week from an acquaintance, who actually didn't send it to me; I clicked on it

http://whaouh.com/newnews.facebook.com.foxnews3.php

It was a page in English, could that be where it came from?

Since I'm not always next to it when I turn it on, as it's a bit slow at the beginning, it could date back several days.

Thanks again to you and Erwan for your help.

With the page you give, it's Google that appears.
I think it's a virus because apart from that I don't see what could transform your PC! It's not the updates since there's no Acer anywhere on mine.

Keep us posted after your formatting.

Sure, I'll meet you in a few days after the formatting. A friend of mine is going to do it for me, and he also says it needs to be reformatted, so I'm going to entrust my precious to him!!

Thanks again!

In the future, create an image of your computer with Acronis or Norton
when it's running smoothly
when you have a big problem, revert to the image, it prevents having to reinstall everything!
