Unlike most people who scrutinize their event viewer with paranoia, I have never (in many years) found anything suspicious in my event viewer log -- until now. And, I do have reason to suspect my PC could be compromised by someone.

Look at this event log:


An account was successfully logged on.

Subject:
Security ID: SYSTEM
Account Name: DESKTOP-6KVBGNL$
Account Domain: WORKGROUP
Logon ID: 0x3E7

Logon Information:

Elevated Token: Yes

Impersonation Level: Impersonation

New Logon:
Security ID: Window Manager\DWM-1
Account Name: DWM-1
Account Domain: Window Manager
Logon ID: 0x1DDEC
Linked Logon ID: 0x1DE27
Network Account Name: -
Network Account Domain: -
Logon GUID: {00000000-0000-0000-0000-000000000000}

Process Information:
Process ID: 0x378
Process Name: C:\Windows\System32\winlogon.exe

Network Information:

This event is generated when a logon session is created. It is generated on the computer that was accessed.

The subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.

The logon type field indicates the kind of logon that occurred. The most common types are 2 (interactive) and 3 (network).

The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on.

The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.

The impersonation level field indicates the extent to which a process in the logon session can impersonate.

The authentication information fields provide detailed information about this specific logon request.
- Logon GUID is a unique identifier that can be used to correlate this event with a KDC event.
- Transited services indicate which intermediate services have participated in this logon request.
- Package name indicates which sub-protocol was used among the NTLM protocols.
- Key length indicates the length of the generated session key. This will be 0 if no session key was requested.



Can someone please explain this event, paying especial attention to the Virtual Account status of "yes" which is very rare from what I gather from seeing dozens of other similar posted problems (I have never seen a "yes" here before). And all the items under New Logon. Furthermore, isn't Advapi always a remote item?
