GMER log is clean.
dotmacsyncclient.exe seems to belong to some iPhone, or other Apple mobile device sync program. It should be located in: C:\\Program Files\Common Files\Apple\Mobile Device Support\bin
I don't know what device you use, but most likely, you should reinstall application, which came with it.

Now, let's take a look at your HJT log.
Malware-wise, the log is clean.
I can see, this service running:
-O23 - Service: Apple Mobile Device - Apple Inc. - C:\Program Files\Common Files\Apple\Mobile Device Support\bin\AppleMobileDeviceService.exe
which most likely calls for dotmacsyncclient.exe file
The above service also runs this startup:
- O4 - HKLM\..\Run: [AppleSyncNotifier] C:\Program Files\Common Files\Apple\Mobile Device Support\bin\AppleSyncNotifier.exe

You also have couple of unneeded startups, which can be safely disabled. No actual programs will be removed.
Open HJT, and checkmark:
- O4 - HKLM\..\Run: [NvCplDaemon] RUNDLL32.EXE C:\WINDOWS\system32\NvCpl.dll,NvStartup
- O4 - HKLM\..\Run: [iTunesHelper] "C:\Program Files\iTunes\iTunesHelper.exe"
- O4 - HKCU\..\Run: [QuickGammaLoader] C:\Program Files\QuickGamma\QuickGammaLoader.exe (unless you work as a graphic designer)
- O4 - Global Startup: Adobe Gamma Loader.exe.lnk = C:\Program Files\Common Files\Adobe\Calibration\Adobe Gamma Loader.exe (same as the above)
- O20 - Winlogon Notify: !SASWinLogon - C:\Program Files\SUPERAntiSpyware\SASWINLO.dll
Click "Fix checked" button.
Restart computer.
