I too have had strange things happening to my Windows XP laptop (Dell). I could not open regedit and after trying the search engines (mainly Altavista, I am becoming wary of Google), thinking that I had a Windows technical issue of some sort, I found some sites suggesting a malware problem. So here I am.
As for registering. Well that's a first. I don't usually register.
I am a professional programmer from non-Windows. Accounts/processes with security and privileges are quite common and you learn how to set things up. There are no, or very few, virus/malware/problemware with those other operating systems.
I have not been running Windows/Internet Explorer inside an account with far fewer rights. There are two reasons for this. I was, years ago, of the opinion that all computer use should be inside tightly restricted accounts, but after learning more about the technical internals of Windows (which I still don't know how to program), I decided that the more open/exposed approach might have its own good reasons. So I am prepared to keep going in that direction until someone shows me that the account-based approach is really the only way.
Windows NT has the facilities which provide for multiple accounts for the one natural person and I have looked through them a little. But I haven't put in the time to work with them because I was sure there would be a list of things to overcome. Also, I am not sure whether my setup on my laptop, as done by myself, would stop the unwanted access.
