Windows 7: Explorer.exe 20% cpu usage when idle

Hello, from time to time my computer get kind of slow and the internet don't work (the internet connection is ok) and when I check the taskbar the explorer.exe using 20% of the CPU even when I'm not using any program. Sometimes it gets normal, but this problem keep hapening. A days ago I had a Malware.packer.gen but it was deleted with Malwarebytes Anti-Malware, it may have some relation? If this is not the right place to this post, just say to me and I will fix it. Thanks!

What's caller64.exe?

You'll need to enter "Programas" and post a screenshot as well.

Kaspersky TDSSKiller and ESET online scanner didn't find anything. The caller64.exe seems to be from my samsung printer. Here are the programs. The problem dissapeared for now, but as I said it keep coming back from time to time.

This happened to me... Try CTRL+ALT+DEL and open task manager and kill all apps, or simply restart the computer to restart all programs (explorer)
