Well , there are so many good anti virus used now a days.
but in my opinion Nod32 is best in the business.

It has the best security features available in it.
I am using it for both office and home.

In office till now we have not faced any problem of security .
Nod32 takes care of all kind of viruses
We only use Internet without being worried about viruses.

Moreover It is developed by ESET, one of the best anti virus brand.

You can download it using the following site:

Just download it and than install in your system.

Scan your system to check for viruses. You need to update it after certain period of time so that it can scan the new viruses.
