Use an account on your computer that doesn’t have administrative privileges to reduce the likelihood of installing malware; and to reduce the likelihood of making severe and catastrophic changes to your system.  Password protect the “administrator” account, and create a “limited” user account for daily use.

Most system administrators adhere to the principle of “least privilege”.  That is, users should only be given the least amount of access and privilege necessary to perform their duties.  The more privilege you have, the more damage a user can do; intentionally or unwittingly.
If you happen to run a small business with a file server or a workstation acting as a file server and you have not limited access to critical data from your users, you have a ticking time-bomb waiting to go off.  Run through a scenario of what would happen if all of your data was wiped out.  Is your data backed up?  Do you have redundancy? In this scenario, some organization would cease to operate; in other cases an organization’s operations would be severely crippled.  Don’t be that organization.  Contact TRA for a free consultation and analysis.
