What cannot start is not a threat...
I just want to know your opinion about this:
- Set "security" only for read in registers (HKCU\software..\RUN, RUNONCE) and (HKLM\software..\RUN, RUNONCE).
- Block the use of windows explorer for internet browse(use firefox, opera...)
- Turn off file share and printer share in net config(where the fixed ip is set).
- Turn off ICMP.
- Only let to log as an user (not administrator).
- Have a quite good antivirus program(avast, nod, avg...)
- Use any kind of firewall properly set(kerio, zone, sygate, isafer...)
- Screensaver and other such type of software set to block.
- Turn off some services...
- Alternative for ICQ and for outlook.
- Some antispyware software
- Teach not to click on any "unknown" links.
Is it enough for a computer protection?
I am "building"a computer for my cousin(16) and I think, that is enough for her safe browsing.
