High Memory usage

That definitely is excessive RAM usage!

What is your Operating System and what version of Immunet are you currently using? Just mouse over 'About' on the lower right side of the UI and that will tell you what build you're using.

Was Immunet running any scheduled or manually launched scan during that time of excessive RAM usage?

Do you have any programs that very frequently or constantly write to disk such as a backup OS shadow copy or similar software package?

Operation System: Windows 7 SP1, with latest KB updates.

Immunet version: 6.3.0.10988

No. I'm not using scheduled or manual scan at the time of high memory usage.

These are my programs that may have high file/disk io, but I'm not using any of them at the time of high memory usage: firefox, virtualbox, qbittorrent, mipony.

 

Today I noticed memory usage with clamAV enabled has dropped to ~183MB (when only using firefox typing this post). But I think it's still too high compared with other antivirus products.

[EDIT] After using PC for some time and closing all programs, Immunet still uses ~442MB.

I see you're using Oracle's VirtualBox software. That might be the problem.

Other users have run into serious issues while trying to use Immunet in a Virtual Machine environment in the past. Although not entirely impossible and depending on the software it usually takes lots of tweaking with the VM software to get Immunet to function properly.

Immunet doesn't have any know issues running in virtualized environments and has been thoroughly tested in  vmware workstation,  vmware server and  virtual box.  and once even in Microsoft's cloud.

Complaints we've gotten about  running in visualized environments  usually stem from unrealistic expectations of performance on non-dedicated hardware  (i.e. cloud hardware thats randomly shared with strangers (e.g. the free trial and budget tier's of google, amazon and Microsoft clouds).   There is just too high a chance someone like me is  sharing hardware time  and  already pushing the machine to it' s limits (see paragraph below:)

To set  some hardware expectations,  I test Immunet on a local desktop  running dual xenon e506  2.13Ghz CPU's  +12 gb ram (ouch), and   2 independent  scsi  1TB drives ( one dedicated to my os & apps, the other  dedicated to vmware images)  and it easily simultaneously powers  my win10 working desktop (chrome, waterfox, and IE browsers, email, visual studio, and an Android Virtual device)  plus 3 copies of immunet running on vmware workstation images for  win7x32, win7x64,  & xpx32.  It can also power an additional  win 10x64, but at this point the images start to chug ( I think disk  bandwidth is the bottleneck).

 

  I can easily run this same level of compute (dektop + 4 images)  + an additional win10_x64  image  on a single more modern Intel i-core 7 + 64gb of ram and 2 sata disks  (one  flash drive for the OS  & apps an  a 1tb 7200 rpm disk for the images). 

 

Getting back to your original problem,  yochenhsieh  you nailed it figuring out  clamAV,  I've seen similar stats with my benchmarking too.  The clam av engine loads it's full virus definitions signature set into memory:  which takes from  100 to 600mb.  add to that the clam  scanning engine  and virus definitions updater and clam alone  can in a worst case  scenario use  in the the 700mb  of memory range.   Currently we have extra experimental blue keep preventative signatures out for a worm we're expecting that are inflating the  usual virus definitions set size.

 

You can try updating the clam av definitions set  via the update button in the gui and running a full scan overnight.  That might get you a smaller more concise set of definitions that'll take less memory  and get you over the initial performance hump of building the local cache up.
