Public bug reported:
Kernel always crashes on attempt to scan /usr with Avira AntiVir.
----------------------------------------
1. Context
1.1. I have two mutually independent installations of KUbuntu 12.x: on a hard
drive of PC and on a flash drive.
1.2. Updates mentioned below are the updates both for an OS and for Avira
AntiVir (of all its components except keys).
1.3. Information about software:
avscan --version
product kind: Avira AntiVir Personal (ondemand scanner)
product version: 3.1.3.5
VDF version: 7.11.77.76
VDF date: 2013-05-08
AVE version: 8.2.12.38
operating system: Linux 3.2.0-23-generic-pae i686
binary target: linux_glibc22
The program is running in fully functional mode.
2. Chronology
2.1. Initially there was no such problem some time before (about 1 month before
now).
2.2. Then the problem appears (probably, after an update) both for the
installation on a PC and for the installation on a flash drive.
2.3. Several weeks later (now) the problem disappears (after an update) for the
installation on a PC. But for the installation on the flash drive problem still
always occurs on any attempt to scan "/usr" (even after an update).
3. Steps to reproduce
3.1. Open a console.
3.2. sudo avscan --batch -s /usr
3.3. Wait (scan never completes).
