My OS is windows XP home edition. I use Comodo internet security and antivirus, Malwarebytes, Spybot, and Sysprot anti-root kit scans regularly and they all report that my computer has no issues whatsoever. I am not running torrents and never belonged to any file sharing service. I am not running to the best of my knowledge any server on this machine. My router has DD-WRT firmware installed and I am not using UPNP and all ports are closed. GRC.com Shields Up port scan returns stealth on all scans. I do have two Linux webservers on my network as well as an FTP server which I never have problems with.
I am a retired engineer but I have no IT skills. I believe my event and security logs are unusual and am asking assistance with an evaluation. At 2am this morning there was a logon and advapi service transmitted over 200kb of info to the web. I am unable to enclose screenshots here so I enclose a link so you may view them elsewhere.
I would like to run Combofix and have the results analyzed, Any assistance is appreciated. Thank you for reading.
