grizz, notice the spelling of
svhost.exe as this is a method of malware writers to confuse users as sv
chost.exe is a needed Windows service that does several things and I notice that you have HijackThis on your Desktop which is not a good place for it.
When you download HijackThis then run its installation application it creates a Folder where it should remain as that is where it stores its Log files to not clutter up the Desktop with its Log files.
Un-install the old HijackThis in Add/Remove Programs and download a fresh copy and install it correctly and run it from the Shortcut created on the Desktop:

Fix checked:
O23 - Service: Windows Telephony (WindowsTelephony) - Unknown owner - C:\WINDOWS\system\svhost.exe
Then reboot.
I recommend downloading Malwarebytes MBAM which is Free then install it then run it and update it with its built in Update function then run a Quick scan and have it remove all that it finds and a reboot may be required to remove locked files:
