Suspicious processes in task Manager

A few days ago I noticed in task Manager the processes are unclear, although earlier they were not, they are called Wahiver64.exe, waspwing.exe, WaspAce.exe, service.exe. They are on the way: Users\AppData\Local\Google\ Several times I deleted this folder with a strange file, but after a while they appear again in the process and the folder is re-created in this way. Antivirus finds nothing, I have Avast already installed for 4 years and during that time never missed a single virus. On porn sites and similar do not come and download verified Repack from Mechanics, Hatab, FitGirl and Phoenix, so the miner should not be. Please tell me what is this strange process can be and how completely to get rid of? Maybe someone had something similar?
