Thank you all, for your timely and courteous replies. I ran Malwarebytes, updated, which found and quarantined the following: Trojan.Agent, C:\Documents and Settings\Admin\Local Settings\Application Data\Adobe\AIH.714e7278dae86a3ba9d9d86878394814b68f93ae\gtbcheck.exe,[f0194df14f2d0c2a479d9d4b99681ae6] I am not using add-ons to CCleaner, and have restored to default settings, including monitoring, which was not running before. After clicking "Analyze Only", and highlighting individual entries, I did not see anything out of the ordinary, nor any references to "winsock", so I allowed cleaning to commence. I have re-started between each of these actions. My problem still exists, that after running CCleaner, my machine cannot find the internet after restarting, until I enter "netsh winsock reset catolog" into "Command Prompt." I'm using Spyware Blaster, updated to the current version. If nothing else, I have learned to control my impulse to throw my computer out the window.

Compliments on a useful application, which at the moment is causing me a headache. Within the last two weeks, CCleaner v4.19.4867 seems to be deleting the winsock catolog, when I run the Cleaner, not the registry tool. I must then reset the winsock catalog, so my computer can access the internet (winsock is the list of instructions which allows my computer to establish a network connection). Then my browser works well, until I run CCleaner again. It has never done this before. This problem began about the time I downloaded the current version of CCleaner. My impression is that CCleaner shouldn't remove anything that would stop my computer from connecting to the internet. Could it be that CCleaner doesn't work on an antiquated machine like mine?
