Thank you to all the people that made the time to reply. I appreciate it.
I want a computer that is as secure as a computer can be, one step short of not having a computer.
Virus, is an apt description of what it does. It is a sickness that not only renders a perfectly good machine to function poorly, but has the capacity to inflict damage to humans as well, by gaining information, and using that to further gain. ( usually money, but also power. )
Not made by clever young kids, as one might imagine, but by cyber criminals, some of whom have (bot) control over 1000000 computers.
The best defense I have been able to come up with, so far, is, as follows:
Avast! free antivirus
Comodo Firewall (stand alone)
PrivacyEraser Pro (settings to 20 overwrites, change filename, reset to zero bytes)
CCleaner (settings to 35 passes)
Keep everything updated at all times. (Browser, antivirus programs...everything.)
Delete all System Restore points, except the latest one. ( reason is, that, system restore points often house a yet unrecognized virus, and albeit, your updated Avast! has since found and eradicated the virus, it remains in your System Restore point. )
Modem kept off when not online.
At the end of every Browsing session, I run all these programs, I run Avast! Full Scan, then Avast Boot time Scan.
But, I don't know...if running a Boot scan negates running a Full scan.
