HELP_DECRYPT has a few different names and you may also come across the terms crypto-virus, cryptoware, crypto-Trojan or crypto-worm, regardless of what this malware is called, what YOU need to know is what it can do and how you should react if it has infected your computer.
HELP_DECRYPT infects your computer by taking advantage of your curiosity
The majority of ransomware is disseminated by email. More specifically, in files that are attached to messages. These spam emails will either look like a tempting special offer that you simply can't miss out on, or they may come via a friend or acquaintance in your contact list that has been hacked. The attachment is carrying the HELP_DECRYPT virus and once you have clicked on the file, video clip or document to open it, it will install itself on your PC.
Some variants if this ransomware may also attack you if you have been unlucky enough to visit a compromised website that has been infected with it.
How do you lower the chances of being infected by HELP_DECRYPT virus? Well unfortunately it is not possible to know in advance whether a website has been compromised but you can definitely be proactive when it comes to emails (and instant messenger chat windows that come with links embedded in them). We've been told it a thousand times, but it is shocking the amount of people who still can't resist opening emails – and even attachments – that come from an unknown sender.
What does HELP_DECRYPT do to your computer?
It has been created to extort money from you. It's as simple as that. And to increase the chances of you giving in to its demands it needs to give you the most cause for alarm that it possibly can.
If you're under attack from this ransom virus your files or documents will be held hostage and you will receive a ransom note, either by email or in a pop-up window that is asking for an amount of money in return for the release of your data or files. The release normally comes in the form of a code that tells you you'll be able to use it in order to unlock your file or files. However, not all of these codes actually work so handing over the ransom is no indication you will even get your files back.
What should I do if I've been infected?
It's easy to say, but try not to panic. And whatever you do, don't pay the ransom unless the encrypted files are very important and you can't afford to lose them. If the encrypted files are not very important or you don't have money to pay the ransom, you can remove try to restore your files (at least some of them) using Shadow Explorer, Recuva and some other specialized tools listed below. Please note that even of you decide to pay the ransom there's really no guarantee that cyber crooks will recover your files. If you have any questions, please leave a comment below. Last, but not least, if there's anything you think I should add or correct, please let me know. It might be a pain but the issue needs to be dealt with – and the way to do it is by not giving in, not paying up and not letting the attackers win.
