Free endpoint security products
While the following products are not necessarily in use campus-wide, they are from reputable companies and score well in independent testing. There are many similar (and also free) products, but we do not feel it is useful to present more than one or two alternatives.
Please note that while the products listed here are free for home use, the companies producing them will often embed attempts to up-sell consumers.
ISS always recommends, regardless of the product used, that users update any definitions on a regular basis – at least daily – and that the installer only be downloaded from the company’s site. Endpoint security products should never be downloaded or installed from third party sources (with the sole exception being the Apple App Store).

Additionally, individuals may wish to use a supplementary malware scanning technology. ISS has had good luck with Malwarebytes, downloadable from the vendor's site.
Formerly, IST had recommended AVG Free as a non-Microsoft product, but this recommendation is rescinded based on their updated privacy policy.
Mac OS
While Apple builds some anti-malware technology directly into their operating systems, Sophos is also available.
