install MVPS or HPHosts
but biq question is what else does the tool bar do and does it have "affiliates" re-read the ULA
I have not read the thread at Kaspersky but you should
did you google the toolbar name?
do a scan with malwarebytes anti malware and let's see if anything else got installed with the downloader packet
what os, browser, firewall and other security software do you run
run the SECUNIA advisor and see if all of your software is up to date
are you running as an admin or have you set yourself up a user account
in other words
how vulnerable are you?
