I’m Being attacked by a virus that does the same thing but drivers are different than the ones mentioned. I’m using Ubuntu 20.04.

Can anyone help on how to fix this?

Get new quality usb flash drive?

Yeah my guess is "bad sector on the Flash drive". Get a new one.

Guarantee you aren’t being attacked by a virus. Same answers for your other thread.

Took me a minute to figure this out. The other thread got closed...The OP here says nothing about thumb drives.
I concur. Use a different/new thumb drive.

How I know it’s malware:
1) I received a threat email
2) Both a Mac and the Ubuntu system were working fine before the email
3) Now both computers present the same behavior wether I try copying to any usb flash drive or hard disk
4) I read on another thread that this can be done by replacing the Ubuntu usb 2.0 driver with a 1.1 driver. I asked the question there but since the thread was 4 years old the moderator asked me to open a new thread. The file names mentioned there are outdated and seem to be different in Ubuntu 20.04
5) if this isn’t evidence enough, the hacker got into my windows computer and corrupted the boot sector.
6) The point of the attack is to not let me make backups of my files because the copy never gets finished. It starts at 30 mb/s and it stalls at 5/mb/s. When you’re trying to backup 1tb of data from hard drive to hard drive the copy would take forever. Same behavior happens when I copy one directory to different sandisk or Multilaser usb flash drives.
7) On my Mac he did something even more amazing, all text files get copied but when you open them on the other side they are completely filled with dots (...........).

OP: this is complete nonsense, please stop posting things like this. Things like this never happen.

Prep (or have a friend prep) a USB drive with a live-cd iso file (perhaps using one of the tools in my signature) and with ClamAV on it. Boot to that and use clam-av to scan your drives. 99.9% chance that if there is a virus present CLAM will detect and report the virus. I am betting there is no virus, but this is the test you should run to be certain. One might also use a CD-R disk loaded to boot a Linux image with Clam.

Running ANY AV detection from within the CORRUPTED OS is futile, a well crafted virus can use the OS facilities to hide itself. Booting a different OS from a USB device or CD avoids that issue.

Have you taken the Mac and Windows computers to a shop to be looked at professionally (the Mac to an Apple Store, in particular), and if not, why not?

Pesonally I would line the machine room with tinfoil!!!

wpeckham, thank you for your reply. I ‘m using eset antivirus. I found out the reason why the antivirus doesn’t detect it is because what he does is replace the usb 2.0 driver with a 1.1 driver. Like I mentioned this post
https://www.linuxquestions.org/quest...device-166981/
Shows that doing this gets me the exact effect that I mention. I just need this procedure updated to Ubuntu 20.04.

Thank you in advance do your help

I find it incredibly revealing that you've chosen to ignore this.

Probably because it’s not actually a virus but a problem of perception. Viruses that perform said actions simply don’t exist. Making a virus that slows a USB copy just to prevent someone from doing a backup is ludicrous. A new USB stick would probably fix the issue but this is apparently not what OP wants so this thread, like all others about the exact same “mysterious virus” activity will continue ad infinitum.

I guess it could be possible that some email did some damage to two systems. It is not impossible. It is possible that some uefi damage could do that but the odds I'd think are very low.

It should be easy enough to burn a cd/dvd of some live distro and boot to confirm either software or hardware issue.
