There is quite a bit of information on the net about it, and if you are worried, go to your antivirus manufactures support page and type the problem in, (DNS Changer) and you will find full details of how to check for it, and how to delete it. (If you have kept your security program up-to-date it should have blocked it as it has been known about for quite some time, however it’s always good to double check in case it got through early on)

Another option is to run a check from a boot disc before the system starts; a good free one comes from AVG and can be downloaded here

WARNING: This affects PCs; MACS & LINUX computers, so don’t get complacent just because you are NOT running Windows.

Above all don’t panic
