Well, not to long ago my computer started booting up slower, still runs fast once booted, however. Everything goes smooth until I type in my password and my computer logs me in. It takes about a whole minute to boot and than at the top left corner I get "Setting up personalised settings for:rundll32 IEDKCS32.DLL.BrandIE4signup". I've read around and people told me it could be a virus and to use Combofix. But I'm pretty chicken to use it unless instructed. Plus, I don't even know it's a virus. Could anyone give me advice?
