Performs virus scanning and disinfection functions in Task Manager at 200+ MB

Hi all,

I was wondering why Sophos is using up so much of my memory, always running the "Performs virus scanning and disinfection functions" at 200+ MB. I looked at some existing threads and disabled on-access scanning, but it had no effect. I have version 10.6.3.537 and running on Windows 10.

 

Not sure if this will help, but these are the components - Thanks for the help!

  • Hello Diane Wang,

    I'd not call 200MB so much - do you think it's causing issues? This question comes up every few months although the only reason seems to be that it's deemed, well, unreasonable.
    As mentioned in other threads it's always a trade-off, memory vs. CPU vs. I/O. If you don' keep detection data and information about files that have already been scanned in (virtual) memory this requires CPU and causes more I/O on a scan. The data is kept even if you turn off On-Access (otherwise it would incur a considerable overhead - you might have turned off OA only temporarily or you could perform numerous on-demand scans). Arguably paging is more efficient here.

  • Hi Christian , i have the same problem.

    I have on-access scanning enabled. Because i think is more security no ? if you disable this function is more easy for infection no ?

    My on-access enable to:

    check files

    write

    change name

    read

    enable detaction

    adware/PUA

    file suspect

    and another options on-access

    I check only scan system memory. --> Its necesary to check this option ?

    Thanks so much for advanced.

  • Hello Cristiano.

    as said, this amount of memory usage is normal and shouldn't cause issues on a decent computer.

    Generally you should use the Recommended settings for Anti-Virus and HIPS (it also explains some of the setting in more detail).

    Christian

  • Hi Christian ,

    the decent computer :)

    we talk about computer with :

    4Gb memory ram

    500Gb HD

    Intel i5

    How the mininum hardware for to work with Sophos ?

    The HIPS is not necessary to setting in option the exclusion windows files ??

    For example in my setting i put to exclusion:

    *.jrs
    *.pst
    bschJW.exe
    C:\MOVENTIA\
    C:\Program Files (x86)\Google\Chrome\Application\
    C:\Program Files (x86)\Mozilla Firefox\
    c:\Program Files(x86)\
    c:\Program Files\
    C:\Program Files\Internet Explorer\
    C:\Program Files\Microsoft Office\
    C:\Program Files\Microsoft Office\Office15
    C:\ProgramData\
    c:\Users\mmartip\Documents\OneDrive - MARFINA,S 1.L\MOVENTIA\
    C:\windows\rescache\
    C:\Windows\security\database\
    C:\Windows\SoftwareDistribution\DataStore\
    C:\Windows\SoftwareDistribution\DataStore\Logs\
    C:\Windows\System32\GroupPolicy\Machine\
    C:\Windows\System32\GroupPolicy\User\
    cloud-drive-ui.exe
    Edb.chk
    GestorIncidencias.exe
    mstsc.exe
    NTUser.pol
    Registry.pol
    Tmp.edb

    Thanks ,

     

     

  • Hello Cristiano,

    the mininum hardware
    if you can run Windows
    and your applications with acceptable performance AV shouldn't bring the computer to its knees (and keep in mind AV is not nice to have).

    As to exclusions: If the above are really exclusions they are not only redundant but also risky (whether a little bit or more than that depends on whether you usually work with a normal account or as an admin). My mantra is exclusions only when proven necessary. We only have a few (not the "recommended" or allegedly even "required" ones) exclusions for some of our servers and otherwise none. Admittedly Windows' self-protection has improved and adding some unperilous exclusions would perhaps save some overhead - but it wouldn't be noticeable anyway.

    Christian 

  • Hello Christian ,

    thanks.

    You recommended not create exclusions. Correct ?

    The exclusions C:\windows\rescache\  recommend Sophos Technicians.

    All the users work with single user , don´t work with admin. The exclusion i do apply of endpoints , not server.

    Thanks ,

    Cristiano

     

  • Hello Cristiano,

    use whatever exclusions a Technician recommended - I won't second-guess Sophos. Personally I'm not a fan of proactive exclusions and recommend not to create them unless there's an actual need (i.e. an issue which can't be resolved without applying them).

    Christian

  • Ok.

    Thanks so much

    Crisitiano.
