I am using Norton 360 (it is managing firewall, av etc.) + SuperAntispyware on demand. Am I safe enough or I need more protection in terms of firewall etc... Advice.......
Yes, you are safe enough with Norton 360 alone. The rest is just a bit of a paranoia. Common sense is also an additional layer of protection, sometimes considered to be the most important one
TBH, you are never "safe enough" with software alone. The best defense is safe browsing. Be smart. All the AV/Firewall products in the world won't catch 100% of whats out there.
The best defense is using logic and good old fashion common sense while on the Internet. Also remember that once you hit the reply or send button it's on the Internet FOREVER!
Get Sandboxie for running questionable apps. I like using a HIPS like Comodo with on-demand AV such as Avira. I also run a cloud AV called Immunet which scans all new files.
I use comod Internet Security (AV, firewall, defence plus (like W. defender), etc). Comodo fully free and safer for me. You could try that.
