The single most effective security precaution any Microsoft Windows user can take, no matter what website you are using, is NOT to use any iteration of Internet Explorer.
No, I cannot agree that it ranks as the single most effective security measure.
For me, the three key on-line precautions are:
- Properly configured firewall (preferably hardware with NAT & PAT);
- Up-to-date anti-virus set to on-demand scanning;
- Not to run as an admin or equivalent.
