Hi,
According to TrendMicro, PE_RESOURCER.A is a file infector virus. That is, it infects legitimate files too. In your case, all those detected files belong to legitimate applications, but are infected by virus.
You can boot into Safe Mode, and delete those files. How to boot into Safe Mode:

But, for proper functioning of those software, you need to re-install them.

hkcmd.exe and igfxtray.exe are related to Intel Graphics configuration and hotkey application. Most probably, you will find this in motherboard CD along with the Graphics driver.

This is related to some HP hardware like printer/scanner etc. Probably, this application will be present in the CD that is provided with the hardware.
