Hi,

The logs are clean.
The Hosts file and the ZoneMap were reset.

How ever a few hours after you used your computer the problem returned.

Please investigate the possibility that these .lnks are the carrier.

ultraiso.exe
UltraISO Premium
EZB Systems, Inc.

To check without deleted these .lnk I suggest you rename by adding .old to all the shorcut links.
Such as C:\ProgramData\Microsoft\Windows\Start Menu\Programs\UltraISO\UltraISO Help.lnk.old

Shortcut: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\UltraISO\UltraISO Help.lnk -> C:\Program Files (x86)\UltraISO\ultraiso.chm ()

Read this, you may have to delete the file or add .old extension to stop if from executing.
<<<>>>

This shortcut can be deleted.
Shortcut: C:\Users\Vintage\Desktop\Windows Update.lnk -> C:\Windows\system32\eudcedit.ex (No File)

Restart the computer normally.
If the problem is solved I can give you a fix to remove all traces.
<<<>>>

If the problem persists have a look at your Router settings.

The only thing we did not do is to reset your router. It may be infected.

Ultra iso has nothing to do with it - every installer, if I download it, check it on the VirutsTotal website.

Besides, I recently used this ultra iso 1 time since I don't know when even. When my problem started to appear, I did not use it.

I have already re-installed the whole system many times - the problem came back every time.
I have already reset the router to factory settings many times (while formatting the computer, I wrote about it earlier and it did not help) the problem kept coming back every time.

So after 2 weeks of torment and attempts that did not solve my problem, I decided to buy a new hard drive and:

1. I disconnected the computer from the network completely (I do not have a wifi in my PC, cable was pluged off my pc)
2. I have disconnected all hard drives.
3. I took out and put the CMOS battery, RAM and Rested Bios in.
4. I Fleshed BIOS.
5. I have connected a completely new hard drive.
6. I have installed the system from a bootable USB flash drive (new - never inserted in my PC before)
7. I installed the basic drivers (Realtek, Lan, Usb from the manufacturer's board of my motherboard).
8. I installed the NVIDIA graphics driver and firefox browser - the installs were copied from my brother's computer (which is on the same home network, they were all freshly downloaded).
9. I updated my computer overnight.
10. Today on 15/11 the problem has returned.

I am an IT specialist myself and I have never dealt with something like this - no scans and restarts - of the router - the disks, the system do not work. At this point, all I can think of is: is it possible that some virus site has my IP address? and that's why this problem comes back ??? what the F$ is this with !? I have 2 other computers in my network, they are all connected the same as mine, i.e. and they dont have my problem.

My PC, PC2, PC3 = connected to a switch and this is connected to a router that provides internet access.

My PC, PC2, PC3 <-> Switch <-> Router <-> Internet

What else can I do ?
Ask to change my IP address of my ISP?

UPDATE:

In 'Windows Firewall and Advanced Security on Local Computer' I added 1 rule for inbound and outbound traffic in tabs (Outbound Rules / Inbound Rules) blocking the IP address which I added at the beginning of this topic in the attachment. (fwcdn.png attachment in my 1 post in this topic) (see attachments outbound / inbound rules)

When 'this' $ hitstorm started (2 weeks ago), I installed the mbytes program for the first time and it blocked the outgoing traffic to the fwcdn.pl domain from the browser several times (see attachment: fwcdn.png).

After adding these rules (I do not know if I added them correctly) So far no browser opened by itself but I will wait and inform you.

I also talked to my internet provider and he said: that although I seem to have a fixed IP, it changes every now and then (the server allocates other ~~ and that he strongly doubts that 'something' connects to my computer only from outside- and 2 others in this the same network are healthy)

PLEASE consider the possibility where this 'virus' may have its source on my computer:
1. I have no external drives or foreign USB
2. I formatted my computer multiple times and bought a new disk - the virus still came back.
3. I fleshed the BIOS (2 times) - that didn't help either.
4. I have reset the Router (many times) - that didn't help either

So it turns out that this 'virus' is sitting somewhere in my computer,
where can he be? what could its location be - and how to get rid of it?

-processor?
-motherboard?

I guess only these places were left to be explored - nowhere else can the virus nest ???

Hi,

There is no virus or trojan on you computer.

Your IP address assigned by your provider are being ping.
If found you get the popup.

The IP address is blocked.

You can also block the domain fwcdn.pl with the HOSTS file.

Add the following line to the HOSTS file.
Leave the current information as is.

127.0.0.1 fwcdn.pl

Make sure you save the file before closing it.

===


I will leave the topic open for 6 days,
You can return if needed.

p.s.
Learn about the HOST file.

So u are 100% sure there is no chance dat wirus is on my computer?
So if i understand it what u say: there is some constant pinging my ip from some outer source???
So the only TRUE solution is: realny change my current ip adress? is dat correct what im saying?

Can u guide me how to block ping (my pc ) from outer sources (step-by-step) so no1 can ping me in future?

Update: eh. default browser still opening by itself. Should i block whole imcp pinging for outbound traffic?
Will windows and other programs run properly when I do this?

Update: i done this for ipv4 for inbound and outbound traffic and browser still opening by itself sometimes 2 at once
i done this also for ipv6 for inbound traffic and browsers still opening. cant do this for outbound rules - anyway At this point i dont even know if its a correct way of proceding.

maybe i setted them in wrong way i dont know ...

Hi,

Edit your HOST file again.

::1 localhost

Leave a space after ::1 and edit your previous entry to:


0.0.0.0 fwcdn.pl

Save the File.

Restart the computer normally.

If the problem persists then these are pupups are being generated if some Browsers are Synced with other devices or from what is know at PUSH notification.


Malwarebytes's push notifications blog.

Folllow the instrutions.

Restart the computer normally.

If you need Malwarebytes install the Free version.

Please download Malwarebytes Anti-Malware from Malwarebytes or
