How to Prevent Ransomware From Locking Your PC

  • 48
    Shares

The Quick Heal Threat Research Lab has been detecting increased numbers of ransomware infections over the last few weeks. We have recently reported on the notorious Dridex ransomware. These incidents depict a clear trend that malware authors are steadily shifting to serious money making ransomware variants.

The rise in these ransomware variant detections can be attributed to the following primary reasons:

  • Ransomware has proven itself as a highly effective money extortion mechanism over the last year.
  • Ransomware has become much easier to develop due to the availability of source code and the emergence of ‘Ransomware-as-a-service’ products in the black market.
  • Ransomware is increasingly being used along with other successful and penetrative malware propagation techniques such as spam campaigns, ‘Malvertising’ and ‘Social Engineering’.
  • Ransomware has become efficient due to the presence of Bitcoins, a digital currency that enables cybercriminals to collect money anonymously.

Stats for Ransomware Detection by Quick Heal

This graph shows the number of ransomware detections by Quick Heal for the 7 weeks starting from February 1st, 2016. In this time period, our lab has detected nearly 450,000 ransomware samples, which work out to approximately 9,000 ransomware detections every single day. These figures present a considerable rise in the ransomware detections that we have seen in the past, and they highlight the growing threat of ransomware to businesses and individual users.

How to Avoid Ransomware Infections

There are a few foolproof precautions that need to be undertaken to prevent ransomware variants from infiltrating and locking your machine. These safety guidelines are even more relevant for enterprises and small business owners who are often the most sought after victims of ransomware authors.

1. Backup your data often and in different ways

When it comes to data security, the first step is data classification. It is essential for data owners to segregate their data into crucial, moderate or dispensable categories and then devise ways to secure their most sensitive information. We recommend the 3-2-1 rule – maintain 3 different copies of data, in 2 different formats, with 1 format available offline.

2. Update your OS and other applications & utilities

Malware developers typically exploit vulnerabilities in applications and the OS to breach system security. To prevent incidences it is highly recommended to automatically download OS updates, and apply regular security patches for other applications on the system. Commonly targeted applications are Java, Adobe Acrobat Reader, Adobe Flash Player, MS Office and web browsers such as Google Chrome, Mozilla Firefox, Internet Explorer and more.

3. Be cautious of suspicious emails and attachments

Spam emails have become one of the most effective ways for ransomware to enter vulnerable systems. Through social engineering techniques or by disguising emails to appear as authentic ones, attackers cause victims to click on fraudulent links or download malicious attachments. When it comes to email security, we suggest the following security measures:

  • Always check the email senders information
  • Always verify the content of the email properly
  • Never click on the links embedded within suspicious emails
  • Never open or execute attachments received from unknown senders

Some More Ransomware Prevention Techniques

  • Personalize spam settings for your email inbox and your installed security solution.
  • Use the native Windows functionality of ‘Show File Extensions’. This shows the extensions of unknown files before opening them.
  • In case of breaches or infections, immediately disconnect the Internet connection.
  • Keep the Windows Firewall switched on at all times and regularly monitor its settings.
  • Enable your installed security software to scan compressed and archived files when they enter the system.
  • Turn off AutoPlay for USB devices, so that they do not immediately open the files within them.
  • Consider installing an add-on which blocks automatic pop-ups on your browser.

Recently, ransomware infections have begun spreading via JavaScript codes on websites as well. So there are multiple avenues through which ransomware can be delivered into vulnerable systems. Quick Heal defends against the latest malware samples with generic and heuristics-based detections that are discovered through our global virus signature database on a daily basis. Moreover, Quick Heal security products also provide multiple lines of defense such as Virus Protection, Email Protection, DNAScan and Advanced Behavior Detection System for complete system security.

This is useless product when comes to Locky Ransome malware virus which did not even prompt for malware when our server was hacker which had 15years data. We have been using this product for 7-8 years with regular updates and timely activation done for 3yrs. There customer support is never reachable as we need to wait for 50-60 mins but no one will come on line. If any tech comes online they simply do not understand the issue and say we are helpless. THIS IS USELESS PRODUCT, NO SUPPORT, WASTE OF MONEY. THEY ARE THE BIGEST HACKERS WHITHOUT PROVDING SUPPORT.

These ways of protection are not enough. Can this ransomeware be completely removed from machine by rebooting, and can be repaired by Quick heal total security? Or you have any other option.

Yes, I trust Quick Heal but I am using Quick Heal Internet Security version 16.00 (9.0.0.54). When I upgrade to it’s latest version version 17.00 (10.0.0.6) it consume more RAM & slow down my PC, increase startup & shutdown time. That’ss why I am using version 16.00 (9.0.0.54) again. Also When start LIVE CHAT on your website, I did’nt received Chat transcript but it show Mail has been sent successfully.

QH isn’t as effective as MS Security Essentials in detecting and killing ransom virus. Org. like QH should find soln. to unlock files affected by ransom as a service to its reg. users.

QH updating is fictional and not practical or real, for QH cannot remove or fight with ..ware effectively and after each update my PC gets slow in operation.
