CPU-intensive (but AV-clean) executables causing sluggishness

    Dear Tech Support Guy community,

    My PC (info below) has been sluggish for a while, and having lately kept a close eye on the most CPU-demanding processes under Task Manager (under zero-load conditions, i.e. empty taskbar), I have a list of three suspect executables.

    • ZenworksWindowsService.exe - part of the Novell network software that is embedded with this PC's OS
    • id_tray.exe - runs iDrive, a cloud backup service that I've set up to run daily, typically from 3pm till about 3:20pm
    • WmiPrvSE.exe - apparently a legitimate Windows service
    The AV that is installed on all my company's PCs (of which this is one), SOphos, has, for some reason, stopped updating correctly for a while, as you can see int he log below. Since I never found that particular AV helpful anyway, I've scanned the above 3 exe's at virustotal.com, which I'd have thought is also more up-to-date. All three of them seem clean, even after requesting a re-analysis.

    How else can I check whether these exe's have somehow become infected/hijacked? I am not really up-to-speed with how the latest malware infects PCs nowadays, so it might not be as simple as it used to, i.e. identifying&cleaning specific exe's. I know HijackThis is a very good tool for detecting malware that hijacks a PC's resources, however afaik it is for *browser* hijackings in particular, whereas right now my suspicions lie with the above-mentioned exe's.

    I should add that I am using the free version of "Windows 8 Firewall Control" (even though I run Win7), which unfortunately gives the user no control over exe's located in system folders (which is the case for WmiPrvSE.exe).

    Thanks in advance for any help!
