i've heard about nod32 a lot. maybe i will give that a try. is there a way to serialize the two tasks (a/v scan / defrag)? sometimes people stay back late at night and they terminate the task. is there any way to avoid that?
You can lock the pc so no one can log in except you this is how you do it:cheesy:
Manually locking your computer
There are three popular methods of manually locking your computer; choose whichever method is easiest for you or best serves your needs.
Method 1
You can use a key combination of the Windows logo key (it is typically located beside your Spacebar and has the flying Windows logo on it) and the l key (the letter l) to immediately lock your computer.
Method 2
Press Ctrl-Alt-Del. In Windows 2000 or XP, click Lock Computer. In Windows NT, click Lock Workstation.
Method 3
You can create a desktop shortcut that will lock your computer when you double-click it:
Right-click the desktop and select New, then Shortcut. This will open the Create Shortcut Wizard.
For the location of the item, type the following:
%windir%\System32\rundll32.exe user32.dll,LockWorkStation
Click Next.
Type an appropriate name for this shortcut and click Finish.
You will now have a shortcut on your desktop that will lock your computer when you double-click it.
Locking your computer through the screen saver
To set up your screen saver to automatically lock your computer, follow these directions:
Right-click the desktop and select Properties.
In the Display Properties window, select the Screen Saver tab.
From the drop-down list, select a screen saver file.
In the "Wait:" field, set the amount of time you want the screen saver to wait for activity before starting.
Check the Password protected or On resume, password protect box, and then click OK. From now on, when the screen saver comes on, your workstation will be locked.
However you choose to lock your computer, to unlock it, press Ctrl-Alt-Del. The Unlock Workstation or Unlock Computer window will appear. Enter the password for the username under which you're logged in.
Administrators for either the local computer or the domain can unlock a locked computer by entering their username and password at the login prompt. This will log the current user out, but will not log the administrator in. At this point, any user with login rights can log into the computer normally.
Note: If you are the local computer administrator, you need to log into the local computer rather than the domain. Also, by using the administrator login to unlock the workstation, you will erase all unsaved work.
If your domain username is in the Administrators group, then you can enter your domain name and domain password and select the proper domain from the drop-down list. You are not required to log into the local computer. This will also unlock the workstation and erase all unsaved work.
