Just switch to NBN.
This morning I received an email that my OISS had been cancelled. I phoned customer care and was told to renew online. I tried this and got message Optus Internet Security Suite is not currently available with your broadband service. Phoned Customer Care on 133 937 and was told Optus didn’t provide internet security for NBN.
Now without any warning my computer says it is unprotected.
What is another good antivirus program? I really liked the one I had.
Recon if you put that quote into Google you'll get a few good hits.
A paid antivirus software does have a number of advantages over its free counterpart, and this is its far more comprehensive cover and protection. First of all, paid versions are easier to install, do not have advertisements attached to them, update simultaneously, automatically using the latest virus information and offer additional features such as parental controls. Paid virus protection systems often include useful extras such as backup and recovery tools, useful if your PC crashes, and performance enhancement utilities that ensure that your laptop or PC are running at their most efficient. There is also the advantage of high quality customer support and technical back-up, often lacking in free software versions.
