Just received an email from our ISP explaining, "... your computer or another computer on your network may be infected by malicious software known as "DNSChanger." It goes on to say, "Currently, it is not known whether or not this industry-wide malware attack impacts anything other than web or advertisement redirection and there is no tool that is known to be
effective in detecting and eradicating this infection from infected computers." They strongly recommend updating our master boot records and reformatting our hard drives. Pretty extreme.
Does anyone have experience with this and know whether these measures are really necessary?
Thanks for any help you can offer.
