Checking for viruses on a flash drive using linux?

Question

linux

Hello. At work, I was given the task of installing ubuntu on a computer and using it to check flash drives for viruses. Can ubuntu detect viruses that were written for windows? And how to look for viruses?
PS One user brought a flash drive to work, and there were viruses on the flash drive. We decided to put a separate computer on which we will check flash drives

Answer 1

Of course, you can open the site virustotal.com from this computer on Ubuntu and throw files there one at a time, checking if they are viruses. But if your time is worth less than an annual subscription to an antivirus, I think I agree with paran0id : run from there. Where the work is organized so illiterately - fakap is inevitable, and you will find yourself extreme.

Answer 2

Well, this clearly requires an educational program.
Antivirus is a program. Initially, in the days of DOS, antiviruses were only scanners: the program scanned the RAM and disk, looking for what looked like viruses. Later, resident antiviruses appeared that monitor the activity of viruses.
An anti-virus scanner that looks for viruses only on the disk - it is quite easy to port to almost any operating system, since it works exclusively with standard file operations; non-standard are access operations to areas of the disk that are not part of the file system, such as MBR.
The search for viruses in memory and the resident operation of the antivirus are very difficult to port, since the corresponding mechanisms vary greatly in different operating systems.
Fortunately, you only need to scan for viruses on the disk for your task (a flash drive is equivalent to a disk in this context).
The easiest way is to use a simple scanner from a flash drive - like "DrWeb CureIt!". This is a minimal Linux and program from DrWeb.
The disadvantage is that this system does not have an automatic update, it must be updated manually.
In principle, you can put on a Linux machine; and put an image of a bootable flash drive or a bootable CD-ROM into the virtual machine (a real CD-ROM is slow, but this does not matter for images). Well, Linux itself will download the latest version of the antivirus as needed.

Answer 3

It depends on the base of the antivirus. Ubuntu itself is not an antivirus.

Answer 4

Antivirus boot disks (Kaspersky, Dr.Web) are based on linux. Naturally, the "acting component" there is not Linux itself, but eminent anti-virus software. There are also antivirus distributions for installation on linux.
There are also open antiviruses, for example, ClamAV, but I would not trust this. Buy a normal antivirus.

Answer 5

Prohibit the use of any flash drives on working computers.
This is the only easy and cheap way out.
Slightly more complicated is the configuration of local/domain policies.
Even more difficult - all of the above + the purchase of comprehensive data protection.

Answer 6

Check with those who set it how to complete this task.
It is not known what they meant and why.
