I have problem with VDI

Hello, 

SEPM gives notifications about NETWORK VIRUS DEFECTED and source of this virus are THIN clients and they haven't installed SEP Client, because of low disc space I can't install CLIENT soft for them and I'm interested if there is any solution if I can instal there any SEP agent or something like this to scan these virtual computers without installing full SEP client.

Clients using WIN7

SEP version is 12.1.5 RU2

Also I have situations where SEP icon shows that "There are multiple problems (2)" and I cant identify what problems there are.
