High CPU usage on IPS

Question

Hi guys
I got a problem with an IPS, from some weeks the CPU has been at 100% (all the 4 CPU's) and I don't know why, the Inspection Load is really low and I guess this is not affecting to this. Here some information of the SHOW VERSION command
*I also attach some images of the IPS*
Cisco Intrusion Prevention System, Version 7.1(1)E4
Host:                                                    
    Realm Keys          key1.0

    Signature Update    S807.0              2014-06-13   
OS Version:             2.6.29.1                         
Platform:               ASA5585-SSP-IPS10               
Using 4428M out of 5839M bytes of available memory (75% usage)
system is using 25.1M out of 160.0M bytes of available disk space (16% usage)
application-data is using 68.0M out of 171.6M bytes of available disk space (42% usage)
boot is using 56.0M out of 70.5M bytes of available disk space (84% usage)
application-log is using 494.0M out of 513.0M bytes of available disk space (96% usage)
I hope somebody had some idea what could be causing the high cpu usage.
Regards

Has this been something that just recently started happening, or have you had this issue for a while?  Have you installed any new programs recently?
You may want to download Glary Utilities, which is a free software(they will ask you if you want to go Pro, just say no, the free version works very well).  There is a module for startup manager.  You can go in and disable stuff that starts with the computer.  I would advise unchecking adobe, java, quicktime, printers, etc.  Anything that doesn't REALLY need to start with the computer.  The nice thing with Glary is that you can restart the computer, and if you find that you need one of the programs to start with windows, you can go back in and enable it again.
The Celeron 925 processor in your computer is a decent entry level processor, but if there are too many programs running in the background, it can bog down quick.  I would also recommend downloading and running Malwarebytes Anti-malware, to be sure that there is nothing malicous running in the background.
