A lot of the famous names belonging to the PC security providing tools which will release your PC from ransomware, but they do not charge for the privilege. As a result, in this guidance, we will introduce to you some of the best anti-ransomware software as well as the Avast ransomware shield, and of course, you can own it for free. There are also several dedicated tools to prevent your programs from ruining on your PC at all.
Before you get started, it is essential for you to aware that there are two crucial kinds of ransomware: a typical ransomware that can encrypt your files and it may directly delete your files in case that you did not pay any fee (like WannaCry); on the other hand, a ransomware locks you out by interfering you with your desktop. Luckily, there are free tools as Avast ransomware shield to defeat that both ransomware types.
If you have not been a victim of a ransomware attack yet, but you want to save your PC proactively in order not to meet any problems with the ransomware, consider a tool like “ZoneAlarm Anti-Ransomware”, which can be used as behavioral analysis. Its core benefit is to identify processes that act like ransomware – even if it has not become a specific known threat and it automatically backs up your files whenever it finds out anything. Otherwise, it also requires a subscription fee, so that we have not included it in our key round-up, but it costs $1.99 per month for one PC, which is a modest fee compared to these ransoms charged by the criminals.
I. The Avast ransomware shield
Firstly, we will refer to the Avast ransomware shield:
Avast Internet Security or an avast ransomware shield is a full-scale suite, with a robust firewall, an antivirus, a wealth of bonus features, and a simple spam filter. Based on your demands, the company’s free antivirus could be more cost-effective.
1. Main Window of Avast ransomware shield
If not using for the window caption “Avast Internet Security”, you would not be able to distinguish this suite with Avast Free Antivirus. Both of them use a similar dark theme with a big status indicator available on the main page, and a simple menu down the left.
2. Cleanup Premium of Avast ransomware shield
Even though you have bought the suite, some apparent bonus features turn out to ask you for an extra payment, among them Driver Updater, Cleanup Premium, and Secure Line VPN.
3. Avast ransomware shield’s Firewall
This part consists of a robust firewall which handles attacks from the outside by the way of putting all ports in the stealth mode and prevents betrayal from the managing programs that aim to enter into the network.
4. Avast ransomware shield – Ask Mode
In default, the firewall runs its own decisions regarding of application management. If you change it from Auto-decide mode to the Ask mode, it still automatically configures permissions for known programs. However, it will ask you the way to handle any unknown programs.
5. Avast ransomware shield’s some Application Rules
In the Auto-decide mode, the firewall will make rules for programs which attempt network access automatically. You can see them on demand, and you can also change permissions for any programs you may have mishandled in the Ask mode.
6. Avast ransomware shield
By default, the Avast ransomware shield component saves many types of data files in the Pictures, Documents, and the Desktop folders for every user. You can adjust the protected folders and files if you need.
7. Ransomware Protected
When all other protective shields turned off, Avast ransomware shield will come to prevent the real-world ransomware from modifying any files. Notably, do not trust the ransom note in this screenshot.
8. Spam Filter
Avast ransomware shield does not install the spam filter if you do not require. Settings are quite easy, and most users should ignore the sensitivity slider in the default middle spot.
9. Advanced Spam Settings
You are allowed to use the spam filter’s advanced settings to the white-list or black-list addresses or the whole domains, or install it to the automatically white-list address belonging to your own outgoing messages.
It is one of the bonus suite-specific features, which is used by antivirus researchers so as to observe a suspect program’s activity without any disadvantages. Avast ransomware shield allows you to go with the Sandbox to run programs conveniently.
II. Other effective anti-ransomware tool
1. Avast Free Ransomware Decryption Tools
Solutions for defeating various strains of ransomware
Tackles 21forms of ransomware
Not all ransomware encodes data in the same method, so security software providers need to create detailed solutions as new threats. At the moment of writing, the security experts at Avast have developed a familiar avast ransomware shield named Free Ransomware Decryption Tools to tackle 21 various strains of file-locking ransomware.
In order to help you execute and identify the one you truly need, Avast has given a detailed description about the way each form of ransomware works, what extension you will observe on the encoded files, and an instance of the kind of message that the virus inventors have created for their victims.
Once you have downloaded the suitable tool, it will lead you to the wiping ransomware process without paying the criminals, then you will need to provide two versions of the same file – an encoded one and a basic one.
This will be the simplest way unless you did not make a backup before infection, but Avast ransomware shield also recommends some locations where you might be able to look for any unaffected primary files. After that, the tool will compare both of them and use the results to find out the password.
2. Trend Micro Ransomware File Decryptor
A single download that can take 27 breeds of ransomware down.
All tools provided in only one download
Decryption may be incomplete
Trend Micro Ransomware File Decryptor is regularly updated with new ransomware definitions, and it can provide locked files by 27 different kinds of ransomware and their variants when starting writing.
Trend Micro is not similar to the above Avast ransomware shield, it bundles all its decryption tools into one bundle, but you still have to let it know what form of ransomware it is dealing with. Trend Micro’s site gives information to help you determine your particular infection and detailed contacts for its technical support department in a case that you still hesitate.
When completing, let’s provide a sample file for the Decryptor to analyze, then it will work. Decryption can take anything from several minutes to several hours, depending on the kind of encryption has used.
The File Decryptor Tool is not completed – several forms of ransomware are especially tricky and can only be partially decrypted. But the company is constantly working to develop it, and it is a wonderful tool for use in an emergent situation.
3. Trend Micro Screen Unlocker Tools
Release a locked PC, even if you cannot access the Safe Mode.
Can run outside the Windows
Not decrypt files
There are two “Trend Micro Ransomware Screen Unlocker Tools” – one for PCs that are locked so that you cannot enter into the Normal Mode, but you can access the Safe Mode with Networking via the BIOS menu, and another for any cases where both modes are inactivated.
The first one can be downloaded directly on the affected PC with its Safe Mode and Networking.
Once it is installed, reboot the PC into Normal Mode with the locked screen, and press this command: [Ctrl]+[Alt]+[T]+[I] so as to scan for ransomware and remove it.
The other version of the tool should be downloaded using an uninfected computer and saved to a USB stick. After that, you can use to boot the locked machine. When initiating, the unlocker will run a scan and then remove any ransomware it has found, releasing your PC.
Like Trend Micro’s File Decryptor (and unlike the Avast ransomware shield), the advantage of two versions of Screen Unlocker is regular updates to combat new types of ransomware.
4. Bitdefender Anti-Ransomware
A malware vaccination which follows your antivirus software.
Protects from known threats
No behavioral analysis
Not decrypt files
There are a lot of superb free antivirus programs around there, but some of them do not offer the dedicated protection against ransomware. If you are thinking about the potential risk, ”Bitdefender Anti-Ransomware” is a handy supplemental security tool which runs alongside your normal security software to protect from some of the most known forms of ransomware and their offshoots.
Bitdefender Anti-Ransomware currently protects against VTB-Locker, Petya, Locky, and TeslaCrypt, and begins to defend your PC from the aforementioned threats immediately. However, it is just a preventative measure; so if your computer has already been infected with one of those malicious programs, you will have to use one of the tools we have mentioned above.
In case that you currently use the Bitdefender Antivirus, the Anti-Ransomware module has been already set.
5. Kaspersky Anti-Ransomware Tool
Comprehensive ransomware protection for your small business
Proactive ransomware protection
Can undo malicious actions
Monitors network activity
Ransomware on your own computer is detrimental enough, but an infection that blocks you from your business PCs could be an absolute disaster. Your private accounts and client information, as well as work, could all be encrypted – and it could affect multiple machines on a similar network.
Kaspersky Anti-Ransomware Tool for Business is produced to support small- and medium-sized businesses (SMBs) with the aim of protecting their data from such a catastrophe. Like Bitdefender Anti-Ransomware, it’s a preventative tool which was designed in order to avoid infection in the original place rather than decrypt files or unlock your desktop.
Kaspersky Anti-Ransomware Tool runs smoothly alongside your normal security suite, monitoring network activity for things that matches well-known ransomware behavior. The threat database which is reserved on Kaspersky’s cloud servers, so that updates are pushed out to all users at that moment.
