Windows 7 - Anonymous Logon 156 times in 24 hours

This happened 156 times in the last 24 hours & over 300 in the last 7 days. Uhh? Should I be upset, alarmed or concerned?


Although my account is the only one on the computer and it is listed as an admin account I have received errors which I did not have privledges. I do not recall the specifics or times this has happened. But almost always when I dl and try to save to C:\(root) I am denied. Unless these two might be related due to spyware/hacker? I am not concerned about my privledge issues

The Error:
An account was logged off.
Subject:
Security ID: ANONYMOUS LOGON
Account Name: ANONYMOUS LOGON
Account Domain: NT AUTHORITY
Logon ID: 0x1594087
Logon Type: 3
This event is generated when a logon session is destroyed. It may be positively correlated with a logon event using the Logon ID value. Logon IDs are only unique between reboots on the same computer.

Concerned . Run a thorouh anti virus check and malware check.

Priveledge issues are normal. Win 7 is designed to make it hard even for admin to have full control since so many people use their computer soley as admin. The second issue I have no valuable information on though. make sure you are running a firewall and running an anti-virus program.

Are you running Anti-Virus/Malware/Spyware software?

If not, then download one program from each line.

Microsoft Security Essentials OR Avast 5 Free
Zone Alarm Firewall Free OR Comodo Firewall Free
Malwarebytes' Anti-Malware

I ran(1 at a time): Norton, Spybot, AVG and Trojan Hunter. Some 'popular' spyware was found but nothing which seemed serious - would steal CC/PW information.

Cool, cool - thanks.

Are they all the same Anonymous account? Any pattern you can see to the time spacing?

I would definitely do a scan with MBAM, SuperAntiSpyware or something similar. Also, why are you trying to save downloaded files to the root directory? I suggest using the download folder in your profile (or create a folder where you want) and see if that resolves the problem.
