Sometime back, I had an argument with Rogers Mukalele over the choice of antivirus to use. While I suggested that Smadav was enough in a school lab setting, Rogers was quick to remind me that it wasn’t an antivirus. And Rogers was right, Smadav is only a second layer form of protection compared to standard antiviruses.
However, my argument was that, it was useless to have a standard antivirus while my computer still gets infected. Personally, my Internet café in Nabbingo, the only antivirus I use is Smadav and for over 5 years, my computers are always in top form. I also used the same kind of protection at Mountains of Hope Internet Café in Mpigi and for 4 years, the café is still intact with no need for re-installations and re-configurations.
School computer labs, like internet cafes will get all sorts of problems ranging from virus attacks to human related errors. This makes the IT support staff spend a lot of time and resources repairing computers so that the next user gets a smooth experience.
Use Deep freeze
To get an always perfect feel of my PCs, I use a program called Deep Freeze. When installed on a PC, you will request the program to “freeze” local disk “C”. However, to be able to save your work, you will have to deselect all other drives. All data to be saved must be saved in the other drives and not on drive “C”. You cannot save on the desktop or “My Documents” as these files will disappear when you restart the PC.
Deep freeze ensures that whenever the computer is restarted, it goes back to the same perfect state it was. You can never worry about viruses or malicious changes to your computer settings as these will be cleared on every restart.
