Im Sorry ransomware removal instructions

What is Im Sorry?

Im Sorry is a ransomware-type virus discovered by malware security researchers, MalwareHunterTeam. Once infiltrated, Im Sorry encrypts various data and appends filenames with the ".imsorry" extension (for example, "sample.jpg" is renamed to "sample.jpg.imsorry"). Following successful encryption, Im Sorry opens a pop-up window and creates a text file ("Read me for help thanks.txt"), placing it in each folder containing encrypted files.

The pop-up and text file contain identical ransom-demand messages stating that files are encrypted and that victims must pay a ransom to restore them. It is currently unconfirmed whether Im Sorry uses symmetric or asymmetric encryption algorithms. In either case, decryption requires a unique key. Criminals store this key on a remote server and victims are encouraged to pay a ransom to receive it. The cost of Im Sorry decryption is $500 in Bitcoins. This ransom must be paid within three weeks, otherwise the key is permanently deleted, making it impossible to restore decrypted files. Despite these demands, never trust these people. Research shows that cyber criminals often ignore victims once payments are submitted. There is a high probability that paying will not deliver any positive results  and you will be scammed. Therefore, never attempt to contact these people or pay any ransom. Unfortunately, there are currently no tools capable of restoring files encrypted by Im Sorry - you can only restore your files/system from a backup.

Im Sorry is very similar to R3store, MoWare H.F.D, Donald Trampo, VisionCrypt, and dozens of other ransomware-type viruses. As with Im Sorry, these malware infections also encrypt files and make ransom demands. The only major differences are size of ransom (which usually fluctuates between $500 and $1500) and type of encryption algorithm (symmetric or asymmetric) used. As mentioned above, decryption requires unique keys - manually restoring files encrypted by ransomware is simply impossible.

How did ransomware infect my computer?

Most ransomware is distributed using third party software download sources (torrents, freeware download websites, free file hosting websites, etc.), malicious files attached to spam emails, fake software update tools, and trojans. Third party app download sources often proliferate malicious executables that are presented as legitimate software. Most malicious attachments are either JavaScript files or MS Office documents (with rogue macros) that download the malware. Furthermore, ransomware often employs fake updaters to exploit outdated software bugs/flaws to infect the system.

How to protect yourself from ransomware infections?

To prevent this situation, be very cautious when browsing the Internet. Never download software from unofficial sources or open files received from suspicious emails. Furthermore, keep your installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite. Bear in mind, however, that criminals proliferate malware via fake updaters and, thus, using third party tools to update installed apps is very risky. The key to computer safety is caution.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Im Sorry are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
