If I read this right your machine has that backup drive connected all that time. That means any pest that does get through can corrupt or tamper or delete it all.
Let me ask this. If the machine and the attached storage vanishes, will you have the files you can't lose somewhere?
As to security and virus what you have is OK if the owner is not doing things like clicking on every link in emails or using torrents, craks and more. There is no protection known for an unsafe user.
I am running a WindowsXP SP3 Desktop with MS Explorer 8.
I use Microsoft Security Essentials and the Windows Firewall. I also backup my data, music, video and audiobook files to an external drive using Genie-Soft's Timeline 2. Pro.
I do not backup the Program Files from C:\ drive due to space constraints.
1. Am I covered for security, virus and spyware issues. If not, please suggest what I need.
2. Am I covered for backup? Should I be backing up program files? I do have the discs or download sites captured.
Thanks for your advice and help. I just need some confirmation that I'm covered.
