Those using ESET anti-virus to protect themselves on the web have been affected today by a faulty update which was pushed out this Monday morning.
Any user who applied the update was stopped from browsing most of the internet, including SCMagazineUK.com, and ESET's own site.
ESET has confirmed issues via its Twitter feed and on its Security Forum.

The earlier issue is now fixed. Virus signature update V13103 is the latest version and no longer flags false positives. Update ASAP
