RE: there is any way to scan the PC from the ePO ??
you can keep a client task configured with an immediate full scan and then drop this onto machines as you need it and then wake it up.
assuming you have network access and rights and have allowed remote console connections (for the VSE console) you could use the console on the epo server to connect to the console of the machine and then start the default full scan from there. console/tools/open remote console
