Unable to execute scan in Linux, "Useful life of Scan has been exceeded"

GuyDamico

Downloaded and installed SAV for linux today. 

SAVScan virus detection utility
Version 5.27.0 [Linux/AMD64]
Virus data version 5.30, August 2016

Immediately upon installation I received this message:

"On-access scanning not available. It was not possible to obtain or build suitable kernel support."

Subsequently I tried running a scan, here's the output:

guy@guy-Latitude-E4310 ~ $ savscan -f
SAVScan virus detection utility
Version 5.27.0 [Linux/AMD64]
Virus data version 5.30, August 2016
Includes detection for 11781705 viruses, Trojans and worms

System time 10:30:39 PM, System date 06 February 2017
Command line qualifiers are: -f

Useful life of Scan has been exceeded

 

Is there a solution?

    Hello GuyDamico,

    downloaded ... SAV for linux today
    from where? Virus data version 5.30, August 2016 suggests the package is half a year old. This would also explain the It was not possible to obtain or build suitable kernel support as the included Talpa version is very likely too old for your Linux (BTW, it's always a good idea to specify the system's details - uname).

    The obvious solution is to download the current version here.

    I used your link today and I still am unable to run a scan:

    I saw your comment to another post about compiling TALPA.  I have no idea what TALPA is.  I tried a google search on the word without any success.

    Did a revised google search "compile TALPA" and found an article on the Sophos forum.  I don't know if it is still applicable to my situation as there isn't any message about kernal support but I went ahead and executed the command. Here's the out:

    guy@HPDesktop ~/sophos-av $ sudo /opt/sophos-av/engine/talpa_select select
    [sudo] password for guy:
    [Talpa-select]

    Hello GuyDamico,

    savscan performs an on-demand scan and thus file access interception (either Talpa or Fanotify) doesn't come into play. Talpa is required for On-Access ("real-time") scanning, i.e. files to be opened by an application are scanned before access is permitted.

    The Useful life of Scan has been exceeded indicates that SAV hasn't updated after installation. This should be the case only if either the machine has no Internet connection or updating hasn't been (correctly) configured. What happens if you run  /opt/sophos-av/bin/savupdate?

    Hello GuyDamico,

    while there are no precompiled Talpa binary packs for Mint it should compile. Please check the /opt/sophos-av/log/talpaselect.log as mentioned in the Locally Compiling ... article.

    Executing the update command cured the problem.  Thanks very much.
