How to get rid of two Lenovo Vantage files that are slowing down the internet?

Question

Lenovo

My internet was constantly slowing down. When scanning Dr. web cure it, found these two files from Lenovo Vantage.
C:\ProgramData\Lenovo\Vantage\Addins\Lenovo.Vantage.SmartPerformanceAddin\1.0.0.117
ProcBy.dll
SmartCareSDK.dll

When I deleted or moved them, via Dr. web cure it, the internet worked fine. But the next day they reappeared.
Just uninstalling Lenovo Vantage didn't work because the files were gone and the internet was still bad.
Is there anything I can do about it besides reinstalling windows and doing a daily scan?
