Yesterday my computer began a continuous receiving & sending data, as indicated by the twin monitors icon, confirmed by the local area connection dialog box. This happened sometine during the day, absent any unusual incidents. I was editing a local copy of website with MS Frontpage, and accessing Twitter and other CLEAN websites. among other tasks, I was picking up code for Twitter Twee & Follow buttons. These tasks completed OK, and I uploaded revised website to remote server.
On Friday 4/28, I did experience a hang & spontaneous reboot at some point when the monitor was off and no applications beyoond task manager and word pad were loaded. Took several reboots before system restarted with everything running. Initially, desktop loaded with an error message, and Norton Ghost & AV did not start. It is all running fine now.
System connects with internet via Comcast modem, Linksys router. Security: Norton AV 2009 22.214.171.124 updated many times daily, Zonelaram 9.3.014.000 with TrueVector v9.3.014.00, and Spybot updated weekly. Scans with Norton AV & spybot yesterday found no problems.
*Review Task Manager: during continuous send, no additional CPU or process activity. Machine & internet access run at usual fast speed, with no apparent problems.
*Close all apps that might access internet: no change.
*Comment out twitter button code on local copy of web: no change
* engage Zonealarm internet lock. Traffic stops. Releasing lock : No traffic for about 2 minutes, then resumption of continuous activity.
This machine was installed about 2 years ago. Outside of the system problems caused by Firefox, which have all seemed to be self-correcting after a few reboots, it has never exhibited problems, nor has it slowed noticeably, despite the massive accumulation of whatever in that 2 years.
What is happening? This activity cannot possibly be proper, in the absence of any user input or connection to continuously updating sites such as Yahoo Finance. How do I locate & fix?
