This week we were asked to examine our classroom computers and discuss the types of security we have in place to prevent malicious software and/or hackers and to cite any areas of concern. In my opinion, our school software is not very protected. No one maintains the computers on a regular basis. A technician comes in only if there is a problem. We pay for a program that I consider inefficient, as I run one of two different free protection programs: AVG or Panda Cloud. Honestly, we have a minimal firewall. Students can go to any page I believe. The only protection we have is the students have to have an administrator's password to download something. We really need an overhaul and a professional development on how to avoid viruses, Trojans, and worms. Then we need to conduct a lesson with our students so they can be wise users of the internet at school and at home.
We know how damaging the effects of a Trojan can be. My mother-in-law's computer completely crashed. Luckily we have a friend who teaches computer science at a university and builds computers as a hobby take a look at it. He moved all the documents onto an external hard drive, reset the computer to factory settings, complete reformatted the hard drive, and then reloaded the operating system and office suite. He gave us the external hard drive to transfer the documents back to the computer. After we did that, the same thing happened again. He says that it was possible for the Trojan to break itself into pieces and then put itself back together when we restored the documents. That is the current stage we are in. Our friend is going to retake the computer, work his magic, and hopefully the computer will once again work. The computer is only a year old, but if it cannot be repaired, we will have to purchase a new computer for her. Technically she will get my new computer that we were saving until I killed this computer, but either way a new computer will need to be purchased. I kill my computers on a yearly basis. My husband jokes that I need a military grade computer. I just physically beat them up from transporting it everywhere with my school supplies.
