A client has recently been experiencing a lot of internet data traffic on their network which cannot be explained. Speaking to the ISP, they seem to suggest that their may be an infection of some type on the server which was, at one particular time we tested, the only machine connected and turned on. However, we have ESET Smart Security installed and have run several in-depth scans with no results.
Is it possible that the modem is somehow being hijacked, or that the PC is running all these downloads without us knowing? Interestingly, the downloads are often all the same size - 117MB, from memory, which isn't a bit deal until these are dozens of them!!
