Ya will reply back … I did wanted to ask a couple of thing but thought to wait for fix to finish … 1. Should i use comodo secure DNS for internet. 2. I did not visited so many sites after i freshly installed firefox I can make a list of those site & do another fresh installation then check for infection by visiting the sites in the list one by one at an interval of three days to see where i got this infection from so that i avoid that site. 3. If this is not a sites related n the infection is not an addon then what ?.. Sorry if this sounds noob to you. I do not under stand much of what is going on n complying just as told to soo wanted to know …
