Ransomware virus

That page is about SOLO ransomware that gets into PC around the world, and encrypts their files. Here we've gathered full info on what is SOLO, and the uninstalling of SOLO from your workstation. Besides, we'll explain how to restore the corrupted data, if possible.

SOLO is the malicious program getting into machines mostly via e-mail spam and Trojans. Occasionally hackers use exploits to penetrate the PC, but they are quickly fixed. After penetration, SOLO examines the computer memory to find the files to be encrypted and their rough price. Currently, any modern virus is able to cypher image, audio, text and video info in all popular extensions. Virus cyphers all files, but the ones that look like business documents go first. All software on PC will be safe since scammers are interested only in information. The process is made via world-known AES and RSA algorithms, and its complexity is so high that decipherment of information without a key is impossible. This is the ground for such an incredible success of ransomware in recent years: common user, even having a fairly high knowledge of the PC, will never recover the data, and will need to pay the price. The sole way to recover files is to find the fraudster's webpage and get the encryption keys. Some experienced hackers can retrieve the keys due to faults in the code of the virus itself. The corrupted files acquire Tets.txt.solo extension, and requires 0.2BTC for file recovery.

The knowledge of computers is highly substantial in our century, as it helps user to defend the workstation from harmful programs. Unfortunately, 90% of customers see the significance of computer literacy just when ransomware infects their workstations. To guard yourself, you have to keep in mind these few basic rules:

    • Don't ignore the symptoms that your laptop displays. It consumes a lot of CPU resources to encode the information. If you observe an abnormal reduction in computer capacity or detect a strange string in the Process Manager, you can shut down the machine, launch it in safe mode, and run the antivirus. This, if the laptop is really infected, will guard some of your files.
    • Take notice to the dialog boxes. If the laptop is polluted by malware, it will try to eliminate all copies of your data, to make the recovery impossible. However deleting of shadow copies requires admin rights and verification from the user. If you'll stop for few seconds before verifying the changes, it may save your files and your efforts.
    • Carefully examine your emails, specifically the messages which have attached files. The very effective model of fraud e-mails is the story about prize gaining or parcel obtaining. Also you should be attentive with business correspondence, particularly if the sender and the content is unknown. reports, lawsuits, Bills for goods or services, summaries and suchlike important files cannot come accidentally, and the receiver should know the sender. In all other cases it is a fraud.
