I reinstalled my os (Win XP 64 bit) and now IE8 64 bit's Secure Domains immunization fails partially (IE8 32 bit immunization works fine), already tried deleting Sec. Domains-folder from registry and trying again but no luck, still 1035 Sec. Domains not immunizated.
Other active security softwares are Comodo Internet Security 5.10 and Spywareblaster, Malwarebytes Scanner I use once a week.
I use IE8 only on 1 website so not a big deal but still would be nice to have full immunization.
Before reinstallation of os no problems with immunizations.
