By OE6 do you mean Outlook Express Ver 6.
That may have confused us a bit. That's a bit elderly now but If you have EM's you want to keep ? - From memory I upgraded to outlook 7 and was able to keep my EM's.- The Malware detectors are not perfect.
It's a bit of a guess but do you have Malwarebytes on your System I use it personally on XP - Its free but you can buy the Pro Version.
You might have a Malware infection - Downloadable from here
Malwarebytes : Free anti-malware download
The best way is to run it in Windows Safe mode. - But I suggest you try it initially as it comes installed. From memory I don't think it has any browser add ins but be cautious. It has never caused me problems but you can Un- install it from you Sys normally after you have used it.
It needs to have its definitions updated manually - Do this after install. The menu is simple
Also check you Add/Remove Programs for any surprise entries.
Its well worth a try. You may have a browser hijack pest on your Sys.
