Hi:
My system appears to be repeatedly infected.
Please see the following images of "Spybot" and "SpywareBlaster" results:





I typically start by opening "HostsXpert" version 4.3. I then click on: "Make Writeable?"
Then I start Spybot Search and destroy.
After seeing there are problems (Please, see the image above) ........I then click on "Immunize". It then appears to solve the problems.
-------------------------------- and or ----------------------------------
Then I start SpywareBlaster and I see there are problems. (Please, see the image above): I enable all protection and or (on two occasions) check boxes on the custom list.
After doing the above the problems appear to be solved.
Then, I click on "Make read only" in "HostXpert".
However, after re-starting the computer the problems appear to be returning.
Please provide me with Step by Step Instructions that a computing Novice can follow in order to understand and fix these problems.
Thank you in advance.
