ClamAV: Can't read file ERROR

clamav antivirus

When running the command today:

sudo clamscan -r --detect-pua / > clamscan1.txt

I got very many errors going along the lines of these ones (in the txt file):

Is this anything to worry about?

Solution 1:

/sys is the mount point of a sysfs virtual file system:

sysfs is a virtual file system provided by the Linux kernel. By using virtual files, sysfs exports information about various kernel subsystems, hardware devices and associated device drivers from the kernel's device model to user space. In addition to providing information about various devices and kernel subsystems, exported virtual files are also used for their configuring.

The files in /sys are not real files, viruses will not infect them. Also, you can't create new files inside /sys, try it yourself! There's no need to scan it. Use the command line option --exclude-dir="^/sys" to ignore /sys.
