SLocker virus Removal Guide

What is SLocker ransomware virus?

Infamous SLocker makes a huge comeback with 400 new malware versions

SLocker is probably the most notorious Android virus which was also the first one to start using encryption to render victims’ files unintelligible. The virus was first brought to light in 2016 after its active campaign began causing havoc on users’ devices. However, after the wave of initial attacks has passed by, the virus seemed to have gradually died down. Antivirus software vendors contributed hugely to the immobilization of this threat [1]. Besides, the virus itself was not especially well built itself. The victims could simply remove SLocker by performing factory reset even though this meant the loss of the encrypted files. Unfortunately, the malware’s disappearance was merely a calm before the storm, and at the beginning of May 2017, the virus has hit the web with 400 new malicious versions [2]. As expected, hackers were not wasting their time but seriously working on improving these new variants in order to make them more resistant and more effective. It is has become especially difficult to find samples of these parasites since they now tend to use a wide range of different disguises. The virus may even infiltrate legitimate software sharing platforms and spread there as legitimate third-party applications. In such cases, the virus completes all of its predetermined processes before the victims realize they should perform the SLocker removal. Unfortunately, the virus will not leave your device that easily. Therefore, it is much easier to take preventative actions before the virus hits your device. We recommend downloading FortectIntego Cleaner from the Google Play store or install”>BullGuard Mobile Security to supply your device with extra protection.

SLocker virus

SLocker is the virus that set up a new trend of smartphone ransomware which is now growing rapidly not only in Android but across other operating systems as well. Nowadays, people have half their life stored on their tablets and smartphones, including pictures, videos, documents and other data. So, ransomware attack on these devices can have just as harsh of an impact as the encryption of PCs. Naturally, there will always be people who will consider paying the extortionist for the data recovery. However, we strongly advise not to do that. Don’t support the cybercriminals and simply get rid of the virus instead.

Methods Android ransomware may use to infiltrate your device

There are a lot of zero-day vulnerabilities on smartphones and tablets that SLocker may use for the device infiltration. As we’ve mentioned, the virus can be downloaded as regular-looking application which will use modified icons, deceptive package names and obfuscated executables to operate on the devices undetected. Also, the virus may hit the device while visiting corrupted websites which contain infectious ads. These ads will automatically download the malicious payload on the device. Our advice here is simple: stay away from suspicious third-party software, avoid visiting shady websites, and you will not have to waste your time dealing with SLocker.

Preparing for SLocker removal

The essential step of SLocker removal preparation is the acquisition of a powerful malware elimination tool. These tools may help decontaminate the virus, though their effectiveness is not 100% guaranteed. Booting your device in Safe Mode may be helpful. If the data on your device is not especially important to you, you may as well remove SLocker virus by performing factory reset.

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
