For this purpose, u may use TeamViewer or Ammy Admin. Before running scanner, download TeamViewer and double click to Run, when the box comes click Run (Remember, don’t install) in the client computer and take ID & Pass (u have to create 1st time), then run the scanner on infected computer and move to ur computer. Open TeamViewer in ur computer, and follow as above to run it (don’t click Install) and type the same ID and Pass which taken from client computer. This is the safe and u can watch what is going in client computer.
Another way, u can try “EMCO Network Malware Cleaner”. It also helps for remote virus cleaner purpose.
