portability and "sensitive" files

[Admini]

maybe I found out what's happening at work and I've been synced out of sync,
my computer receives policies every hour or so and
I saw these entries in my event viewer / security

Code:

Permissions on an object were changed.

Subject:
    Security ID:        
    Account Name:        
    Account Domain:
    Logon ID:        

Object:
    Object Server:    Security
    Object Type:    Token
    Object Name:    -
    Handle ID:    

Process:
    Process ID:    
    Process Name:    D:\Utilities\PortableApps\CentBrowserPortable\chrome.exe

Permissions Change:
    Original Security Descriptor:    
    New Security Descriptor:

so, the "security descriptor" changes (is different each time) and
because chrome sync is tied to a whole bunch of data of a pc,
it recognized that something has changed, so it requires that I sign in again
(otherwise I could be a.. hacker? for Christ's sake google!)

Is your computer in a domain and controlled by domain controller?
Have you checked chrome://policy and your anti-virus?
