Well, I got sick of it and did a full format this morning. Now, as we all know this gets rid of everything but you wouldn't believe it, after installing all the software and my backup files of last week, now I have windows coming up (2 or 3 different) saying I have problems in my registry and its telling me to go to Registry-Doctor.com or another window comes up and it comes up as reg (something else, have forgotten).com or another window comes up with the same message and tells me that if you have Windows XP, 98, 95, NT, please go to the link below in the window to get your registry repaired. Now, I reformatted the hard drive again as I suspected that my backed up files of only days ago were corrupted and all I have done is put corrupted files back into a newly formatted computer, so what I did is reformatted again and installed my folders and files of 4 months ago which I know are 100% clean. I did not use virtually anything from the computer of a few days ago and you wouldn't believe it, those 3 messages from WINDOWS MESSENGER come up again. Would these be generated by windows? or have I still got something on my computer which is causing this or have I possibly got a corrupted or damaged XP disc with a genuine registry problem? Remember, all messages coming up are different but say I have a registry problem and point me to different sites. Please, someone help me, what could be going on?
