How to Prevent Ransomware

Ransomware is malicious software that blocks access to the system of a computer. To be able to unlock it, you will be required to pay a certain amount of money through a transfer. Numerous people around the globe have fallen victims of ransomware, but thankfully, there are things that can be done to alleviate this matter.

Update Your System

Many people tend to forget to update their system, but this is extremely important to conduct to avoid ransomware from taking place, as well as other negative elements. Today’s cyberattack seems to have come from a bug in Microsoft’s Windows operating system that was solved with the upgrade to the latest version. It is recommended to update the systems to the latest version as reported by the manufacturer on its website.

Don’t Open Attachments from Unknown Users

If you noticed that there is an attachment from an unknown in your inbox, do not commit the wrongdoing of opening like most people tend to do. Instead, you should opt to delete it. If you stop and think about it, it is better to prevent than lament. Via email is how a lot of scammers like to spread the virus and thus make more money.

Likewise, even if they come from known users, always be careful when downloading attachments. Unless you are completely sure of what you are downloading, do not do it or you could put your computer’s privacy in danger.

Don’t Reply to Unknown Individuals

If you receive a suspicious email, delete it completely. Do not opt to reply, as this could only result in you becoming a victim of ransomware in a short period of time.

Don’t Click on Unknown Links

It’s important that you do not click on any links that you suspect. The latest known scam that infected a smartphone of a particular social media user came from a Netflix offering. In that case, it was not ransomware, although it could have been.

Ransomware Notification

The ransomware manifests itself when the damage is already done—when the information has been blocked. A message is displayed on the screen warning you about this and asking for ransom for release.

Do not pay under any circumstance. Paying does not guarantee that you will have access to the data again. If you pay, it is possible that you will be subject to attacks again, since the cybercriminals know that you are willing to pay.

The future of ransomware is not known. Yes, there are ways that you can report the crime, but this crime continues to affect many people on a daily basis. It seems that the only way that it can come to a complete halt is if PC users start to become wiser on the matter so that they don’t easily fall for it.

Take the Proper Precautions

The previously mentioned tips can greatly aid you in never becoming a ransomware victim like so many people have unfortunately already been. From now on, you should put them to practice, as this type of scam is getting stronger than ever. Scammers are finding new ways to get into people’s systems, and thus you should take the proper precautions.


DATA RECOVERY 101

INTRODUCTION

The loss of data can be due to various reasons such as hard drive failure, damage or its corruption, accidentally deleting the wrong files and also formatting gone wrong. However, this process is reversible through data recovery. In most extreme cases such as that of a hard drive recovered from plane crash, data recovery is more complicated than when the information is lost through a simple power outage. Data recovery is process of information retrieval .It basically means trying to salvage the information that has been lost by all means.

 

DISCUSSION

The process of successfully recovering data from a hard drive or a computer can be in 2 categories i.e. logical damage and mechanical damage. These two categories are named after the type of damaged that has occurred on the data.

Logical recovery of data- This is whereby the software has been damaged and the data is not readable. The software refers to the file system or the partition table. The logical data damage is usually caused by: an error by the user i.e. through deletion or accidentally formatting the data, the corruption in the operation system, power loss occurring suddenly, viruses, updates in the operating system especially those done automatically, malware and mechanical failure. Data rescue is the best for logical data recovery.

Physical data recovery -It is also known as mechanical data recovery. It is mostly performed when there is an electronic failure or internally damaged hardware. The symptoms include: clicking noise, beeping noise, buzzing noise, dead hard drive, hard drive not detected or recognized, no power to the hard drive, a slow computer and scraping noises. It is usually due to the machine or device falling, improper storage or handling of the machine, damaged hard drive from the manufacturer, power surges, liquid damage, fire damage and inadequate or poor ventilation in a room. In physical data recovery it is necessary to repair the drive so that information can be recovered from it.

 

CONCLUSION

The technique used in the data recovery depends on how the data was lost for example through file deletion or file corruption. It should be noted that if the hard drive has been physically damage the process of data recovery is complicated and requires a professional specialist. Although the process may prove to be costly at times , it is worth it and the best results are delivered at the end.
