Command-line scan may not start while another scan is in progress, with unclear error
message [61247]
When scanning the system is already in progress (e.g. a task “Perform full computer check” is
running), attempt to start a command-line scanning task (with fsav.exe) may fail with error
messages "Error: Cannot start the scan, try again" and "Error: Unknown error".
Due to the design of scanning the system, certain portions of the scanning task cannot be run
simultaneously. As a workaround, try running the scan a few minutes later.
Quarantining action only available for files on local hard disk [61034]
The quarantining action for infected files is only designed to work for files on the local hard disk.
Files on removable media (e.g. USB memory sticks) or remote (network) drives cannot be
quarantined. For example, when manual scanning setting has been set to “Quarantine
automatically” and an infected file is scanned on a USB memory stick, no action will be done
with the file. To remove an infected file from removable media or remote drives, select the
“Delete” action or remove the files manually.
Infected files from restored folder may not get detected [59875]
When a previously deleted folder (as moved to “Recycle Bin”, not permanently deleted)
contained infected files, and the whole folder is being restored, the infected files may remain
undetected when being restored.
This may occur because restoring a folder from “Recycle Bin” is implemented as a simple folder
rename operati
on, if the folder is located on the same hard disk as the “Recycle Bin” folder.
Real-time scanning does no scan files upon folder rename operations because this would make
such operations much slower. The infected files will be detected and blocked in any case when
being opened or executed from the restored folder, so malware cannot activate on the
computer regardless of this problem.
Progress bar does not account for files scanned inside archives [59503]
Files scanned as packed inside archive files (e.g. zip) are not taken into account in the progress
indicator. For example, if the scanning target includes two equally large zip archives then the
progress bar will remain at 0% until the first of the archives has been completely scanned, at
which point the progress bar will jump to 50%. It will remain at 50% and will jump directly to
100% when the scanning of the second archive file has been completed. If the scanning target
includes a single archive file only then the progress bar will remain at 0% until the scan is
completed.
Infected files dragged and dropped from VMWare host not detected [59093, 59147]
This problem is specific to the product running inside a virtual machine, under the VMWare for
Workstations product.
When a folder with infected files is dragged and dropped from the host computer to the
VMWare guest computer with the Anti-Virus product, infected files thus copied to the virtual
machine may not get detected by real-time scanning. This only happens when complete
folders are copied to the virtual machine: when individual files are copied then real-time
scanning detects the infected files.
