Try restarting the computer.

Avast still uses most of the CPU just not enough to make CPU usage 100%.

Consuming resources is one reason I ditched avast years ago so you're not alone in your complaint.
 
You may want to consider replacing it with another solution which is not as resource heavy.  If you don't mind paying, I generally recommend ESET NOD32 Anti-Virus or Emsisoft Anti-Malware as they are effective but leave a small footprint...meaning they are not intrusive and do not utilize a lot of system resources which slow down performance. Kaspersky Anti-virus is also a good choice for the same reason. If you don't want or can't afford to pay, then I would recommend Sophos Home Free Antivirus, Panda Cloud Antivirus or Bitdefender Anti-virus Free Edition if you prefer not to use Windows 8/10 Defender or Microsoft Security Essentials, the free anti-malware solution for Windows 7 and Vista SP1/SP2 that combines the features of an anti-virus and anti-malware scanner to provide real-time protection.

For more suggestions see Choosing an Anti-Virus Program.

Might this high usage be temporary, as would perhaps be found in the midst of a periodic full background scan, etc..?

 

(UVK has a "Kill all processes" option that might terminat whatever it is, or, alternatively, MS/SysInternal's "ProcessExplorer" should let you suspend/kill whatever tasks are spawning your errant/stubborn task)....

 

(Purely as points of reference, although a Defender scan may only use 12-15% cpu resources, a MalwareBytes scan, while active, hovers at 65-75% during the quick scan during those few minutes (on a 7700K, w/ 32GB of RAM)

Download and run Sysinternals' Process Explorer.

 

Double-click on the process name and select the Threads tab to see which thread is using the largest amount of CPU.

Also, enable the VirusTotal check in Process Explorer by clicking on Options > VirusTotal.com > Check VirusTotal.com
