For those who don't know. DeepFreeze (DF) is the name of a computer program currently licensed by Faronics. The role is usually more or less this. When installed on a computer, DF will take the current state of the PC and record it to a protected file. Because it works at the kernel level (the subject of the operating mechanism), it can record everything that is on the PC today, whether it's a file mechanism, program, data, or anything else found on the hard disk as a DF job. This info is then recorded by DF to the file I mentioned just now.
Deep Freeze Antivirus
It's like a backup, right? True, indeed his role, making backups of the drive specified by the user. If there is a drive that is not in the DF list, it will therefore leave what is there. Nach, if the computer is restarted (re-booted) and the DF is in an active state, the backup file just now will be reversed to the associated drive, nothing less and nothing. Exactly the same info he got when he was active the first time.
If you can make an analogy, DF is similar to a child who is memorizing a word and rewriting it when he wakes up. Memorizing is done once, but writes repeatedly. That's more or fewer DF works
How does this anti-virus work?
Deep Freeze is software that plays a role in keeping your computer still in its initial state. Any changes that occur after the computer is "caged" by Deep Freeze, those changes will disappear after the computer is rebooted.
For example, your computer is attacked by a virus or there is an unexpected composition change or even an error. Because you have installed Deep Freeze, because it rebooted, the computer will return to its previous state as it was before it was attacked by a virus or error. Any changes that occur (including the entry of viruses) when the computer is in a "frozen" state, the transition will disappear after the computer is rebooted. The computer will return to the previous state before the switch occurred.
Advantages of Deep Freeze
- As long as it's "frozen" (frozen), all changes that occur (virus, computer composition, or registry), Deep Freeze can return it to its normal state.
- According to the manufacturer, Faronics, by using Deep Freeze, you can save computer maintenance costs up to 63%.
- Suitable for use for computer networks such as internet cafes, schools, or offices. In some places, several people are connected to the computer. And from quite a lot of people, there could be someone playing around with the computer. In this case, Deep Freeze will help.
Disadvantages of Deep Freeze
- If you forget your password, the computer will continue to freeze. Any transitions you made (installing software, updating antivirus, etc.) will disappear on restart. One way out if you forget your password is to reinstall the computer.
- If you accidentally save a document on a Deep Freeze protected drive, it will disappear when the computer reboots.
- For desktop computer users without UPS, if the power suddenly goes out, unsaved documents will disappear. Deep Freeze retains the role of reconditioned file storage.
- To install a new program or update antivirus, Deep Freeze must be started first. When the computer load is still exposed to the dangers of viruses and others.
- Deep Freeze does not prevent hard disk fragmentation from occurring. You need to recognize, a fragmented hard disk is one of the triggers that causes a slow computer. To perform defragmentation, you must disable Deep Freeze.
Use DF only in special cases
DF is actually good if used in the right place. For example, we have an individual lab whose role is to perform analysis of viruses, malware, or other tasks that are prone to destroying operating mechanisms. Nach uses DF here. And remember, this PC should not be associated with other PCs either via a network or media transitions such as flash disks, external hard drives, and so on. Making it a stand-alone PC. works alone and is not associated with other PCs. tv does require analysis on the network to another PC with DF, so this can be done. But remember, other PCs connected to the network are required to do research. PCs that will more or less crumble if they are attacked by viruses, malware, or whatever we are going to try. Not connected to our work PC which contains important data.
Use Deepfreeze, you won't get a virus
The above is a 100% false theory. Why? This is his narrative:
You have a PC with 2 partitioned hard drives, data, and mechanisms. Usually, people will Freeze on the mechanism partition aka the place where the operating mechanism exists. Then leave the data alias partition where the data is stored. Is that right? Yes, of course, because if the data partition is affected by Freeze too until gray hair can't store data there.
This is what most people miss. Remember, the working concept of the virus will find and destroy the target file. Say the target virus is a file with an exe or doc extension, because of that it will find and (possibly) destroy those files. Nach, a computer that is frozen without anti-virus protection must be infected with a virus. Whether from flash, network, CD, or other media. Then someone said this: "After restarting the computer, it will return to its previous state". Right, then what about the data partition? It doesn't return to its initial state, because it's not frozen. What if when we turn on the PC just now there is a virus that sneaks in, spreading all the files on the data partition or even destroying it. The partitioning mechanism is safe, what about data? Remember, viruses can work in seconds, even milliseconds.
Ah, it's okay, I need Windows to be safe. Tomorrow if someone asks for a coffee program from the data partition so that it will be the most exposed to the virus. Congratulations, you just got a very good partner because, in addition to providing the necessary program, it gives a bonus virus
There is much that can be said regarding the correct use of DF. What's more, if you are a beginner, it's better to function the PC as it should. The enemy of the virus is anti-virus, the enemy of malware is anti-malware.
Can use Deep Freeze to guarantee that our PC or netbook is virus-free even if we don't have an antivirus installed? And can using Deep Freeze for a long period of time on a PC or netbook destroy the hardware of the PC or netbook? Because I recommended a colleague not to use Deep Freeze for a long period?
Using Deep Freeze with the right settings can make the protected drive virus-free even if we don't have an antivirus installed. But hope that Deep Freeze and System Restore doesn't know malware like antivirus but works like a time machine so it has advantages and disadvantages too. The best computers using Deep Freeze are computers used by several people such as internet cafes, public computers, or computer labs at school.
As far as Vaccination is concerned, the use of Deep Freeze in the long term does not destroy hardware, especially PC / Netbook hard drives. But it must be remembered that Deep Freeze does not protect you from physical hard disk damage, so even if you use Deep Freeze you should always cover your important data or consider using G Data Backup which has a power like Deep Freeze and can backup your data regularly. automatic.
Deep Freeze in concept works "similar" to Windows System Restore which saves computer settings at a certain time. He will do a snapshot (photo) of the image of your computer drive/partition at the time you have set and save the image in a protected and "hard" condition against malware interference (I say it's hard to find programs on the internet that can be implemented through deep protection Freeze).
Whenever needed the image can be activated and the computer setup will return to when the snapshot image was executed. To make it easier, think you have a time machine on your computer :) if something happens that you don't expect, for example, there is a driver dispute, malware, setup errors, and other things that cause computer settings to mess up, then you can activate the time machine You and in time all your settings will be reversed and any malware or anything you installed will disappear.
But remember, Deep Freeze is not a bottle genie who can compare which is a good installation and a bad one, so any changes to the computer mechanics will be undone and reverted to its original setup indiscriminately.
Actually, System Restore from Windows gives it a similar role to Deep Freeze, but System Restore Windows has two drawbacks:
- The Windows Restore System Image cannot be stored on a separate drive.
- System Restore can be executed by malware.
If your computer is infected with malware that disables System Restore, you will not automatically be able to restore it because the image is in the same drive partition and System Restore itself has been infected with malware.
Because Deep Freeze reverts back to the predefined image settings that were set up initially, it eliminates all MS Office data transfers, new software installations, cookies, temporary files, and other transitions the mechanism has made on the drives it protects. Therefore you need to be careful and only save data on drives / USB Flash that is not protected by Deep Freeze.
Deep Freeze Security
Deep Freeze cannot protect the operating mechanisms and installed hard drives when the computer is booted from other media (such as another bootable partition or internal hard drive, external hard drive, USB device, optical media, or network server).
In such a case, the user will have real access to the (supposedly) cached content of the mechanism. This scenario can be achieved by configuring the CMOS (non-volatile BIOS) of each workstation to boot only to the hard drive to be protected, then protecting the CMOS with a code.
The next deterrent treatment is securing the PC case with a physical lock or cable tiedown mechanism to prevent access to the motherboard jumpers. Failure to take such action could compromise the protection provided by the software.
Deep Freeze can protect hard drive partitions larger than 2 TB (using NTFS). The advantage of using Deep Freeze is that it uses fewer system resources, and does not slow down computer performance too much.
The disadvantage is that it does not provide real-time protection, as the affected computer must be restarted to remove the malware.
Steps to Install Deep Freeze
- Download the installer on the official Faronics website
- Double click "DFStd.exe". On the first monitor, click "Next". Then there will be an "End User License Agreement" window. Click "I accept...", then click "Next"
- In the next screen, select the drive that you will protect with Deep Freeze. My advice, only specify drive C because drive C is what is called the "heart" of your computer, the place where the OS is. If you choose another drive, you will have to disable Deep Freeze every time you save a file on that drive
- After selecting the drive you want to protect, click "Next". Then click "Install". Wait for the installation process to finish.
Steps to Use Deep Freeze
How to use Deep Freeze itself is easy. To set when the computer is frozen (Deep Freeze is active) or thawed (Deep Freeze is not active), just access the Configure Deep Freeze window. The trick is to press Ctrl+Shift+Alt+F6.
