Semalt Expert De nes Steps To Avoid Ransomware Infections

One of the most dangerous things to infect a computer system is malware. One good example is the CryptoLocker malware which has been a nuisance to online users for a while now. Until a few months ago, experts did not have a de nite solution to ending the menace. The malware locked out over half a million people out of their systems. The government together with some security experts managed to neutralize the threat, and online users can now rest easy. What the government did was that they seized all the computers believed to be the source of the malware.

Later on, an IT company developed a tool which they made public for use by the people who had their computers infected. Its primary purpose was to decrypt any rewalls and recover their lost les.

Oliver King, the leading specialist of Semalt Digital Services, has discussed some compelling issues that will help you avoid dangerous ransomware attacks.

Nevertheless, as much as online users have one less problem to think about, CryptoLocker does not exist in isolation. There are similar malware roaming the internet, with hackers continuing to develop more on a daily business. For example, after taking down CryptoLocker, CryptoWall, took its place. It is a ransomware that has been in existence since November 2013. Since then, over 625,000 PCs containing over 5.25 billion les have fallen victim.

The ransomware is not as complicated as CryptoLocker in infrastructure and source code but does not make it less of a threat.

When CryptoWall gains entry into a clean computer, it scans all the les then uses RSA encryption to encrypt it. Once it permanently places itself in the system, it opens the notepad application with distinctive details about how the owner can access the decryption service. The process will, of course, involve a payment for the service. At a minimum, the decryption programs begin at USD 500 and rise to USD 1000 after seven days. The instructions indicate that the only transactions accepted are in the form of bitcoins and the address to pay changes with each infected user.

The following 9 steps indicate means through which users can shield themselves from ransomware such as CryptoLockker and CryptoWall as they both fall in the category of insidious ransomware family.
