With users getting issues from the picture site recently I thought it might be a useful idea to post what security apps are used/recommended by fellow site users. Might even help out some users keep their personal data safe.
My current setup:
Eset Smart Security
http://www.eset.com/us/home/products/smart-security/
Malwarebytes (Free Version)
http://www.malwarebytes.org/
SuperantiSpyware (Free Version)
http://www.superantispyware.com/
Spybot Search and Destroy
http://www.safer-networking.org/index2.html
Spywareblaster (Free Version)
http://www.javacoolsoftware.com/spywareblaster.html
Free security suites like Microsoft Security Essentials are available as well but keep in mind some free suites are limited to some extent.
Free security apps (Malwarebytes, SAS) all require user to update and scanning, no real-time protection.
