I didn't find any harmful files. And these are the services my svchost.exe is hosting:



Some of them I can disable, but still, why are they taking too much memory?

My memory usage always reaches 85% in computer with 4GB and also in computers with 8GB, which is suspicious. But like I said, I couldn't find any harmful files.

If you have any comments to help me, please do so.
