Is this a severe infection

Sigrun ransomware will encrypt your files, as it is ransomware. It is a severe threat that can permanently stop you from accessing your files. It’s pretty easy to infect your device, which makes it a highly dangerous malware. If your system is infected, you likely opened a spam email attachment, pressed on a malicious advertisement or fell for a bogus download. When it finished the encryption process, victims are asked for a ransom, and if they choose to give into the requests, supposedly, criminals will send them a decryption utility. The amount of money you will be asked depends on the data encrypting malicious program, some demand thousands of dollars, some for much less. Whether you are requested for a lot of money, or a small amount, it’s not suggested to comply with the demands. Think about whether you will actually get your data back after payment, considering there’s nothing stopping cyber criminals from simply taking your money. You can certainly find accounts of people not getting files back after payment, and that isn’t really shocking. Backup would be a much better investment, since you wouldn’t be risking losing your data if the situation were to reoccur. From external hard drives to cloud storage, there are many backup options available, you just have to select one. For those who did take the time to back up data prior to infection, simply erase Sigrun ransomware and restore data from where you are storing them. You will encounter malware like this everywhere, and you will possibly get infected again, so you have to be prepared for it. If you wish to stay safe, you need to become familiar with possible contaminations and how to guard your computer from them.

Ransomware distribution methods

Ransomware normally uses pretty basic ways for distribution, such as through suspicious downloads, corrupted advertisements and infected email attachments. Nevertheless, it is possible for ransomware to use more sophisticated methods.

The possible way you got the data encoding malware is via email attachment, which could have came from an email that looks completely legitimate initially. Once the corrupted attachment is opened, the ransomware will be able to start the encoding process. Those emails normally end up in the spam folder but some people check the folder for possibly lost emails, and if the ransomware email is written at least kind of convincingly, they open it, without thinking about why it landed in spam. You can expect the ransomware email to contain a basic greeting (Dear Customer/Member/User etc), evident mistypes and errors in grammar, encouragement to open the attachment, and the use of an established business name. A company whose email is important enough to open would use your name instead of the common greeting. Expect to come across company names such as Amazon or PayPal used in those emails, as a known name would make the email appear more legitimate. You might have also picked up the threat through some other ways, like malicious ads or bogus downloads. If you are someone who engages with ads while visiting strange pages, it’s no wonder you got your device contaminated. And use only valid websites when it comes to downloads. You should never download anything, not software and not updates, from ads or pop-ups. If a program needed to update itself, it would not notify you through browser, it would either update without your interference, or send you a notification through the program itself.

What happened to your files?

The reason data encoding malicious programs is categorized as very dangerous is due to its capability of encrypting your data which might permanently block you from accessing them. It may take mere minutes for it to locate its target file types and encode them. Strange file extensions will be added to all affected files, and they’ll usually indicate the name of file encrypting malware. Your files will be locked using strong encryption algorithms, which aren’t always possible to break. You ought to then see a ransom note, which should explain what has occurred. It will tell you how much you need to pay for a decryptor, but buying it’s not something we suggest doing. By paying, you would be trusting crooks, the people who are responsible for locking your files in the first place. Not only would you be risking losing your money, you would also be supporting their future projects. The easily made money is regularly attracting more and more people to the business, which is thought to have made more than $1 billion in 2016. Instead of paying the ransom, invest the money into backup. If this kind of situation reoccurred, you could just get rid of it and not worry about losing your data. If you have decided to ignore the requests, proceed to erase Sigrun ransomware if it’s still present on the computer. These kinds threats can be avoided, if you know how they spread, so try to familiarize with its distribution methods, in detail.
