Usam Usam is a ransomware virus of the file-encrypting subtype. This means that Usam applies an encryption algorithm on specific target file types when it infects a computer. However, these are file types are numerous and pretty much include all the most commonly used formats. For example, Usam will most likely have encrypted your images, videos, music, any office documents, PDFs, etc. And what this means in layman\u2019s terms is that as a result of Usam\u2019s activity on the infected machine, all these files will become inaccessible to the victim. There won\u2019t be a program or software application in existence that could possibly open or read these files, hence you won\u2019t be able to use them. That is, of course, unless you decide to pay the hackers behind Usam a hefty amount of money in bitcoin (or whatever other cryptocurrency they demand) in exchange for a decryption key. The decryption key, in turn, is unique for each instance of infection. And after you receive it, it is said to reverse the encryption and make your data usable again. But that\u2019s in theory. In fact, this classic blackmail scheme is quite flawed and there\u2019s actually no guarantee that you will in fact regain access to your precious information. There are many things that can go amiss and we won\u2019t waste your time trying to list them all. But what is important to know is that you also have other options, and none of them will require you to send your hard-earned cash to some anonymous cybercriminals. We have put together a detailed removal guide for you just below this post, which we encourage you to follow in order to remove Usam from your system. And after you\u2019ve done that, you will reach the second part of the guide, which contains alternative file recovery methods. The Usam virus The Usam virus uses a strong encryption algorithm to lock its victims\u2019 files. However, although the process can take a long time to complete, the Usam virus typically runs in the background without exhibiting any symptoms. This is one of the things that makes malware of this type so dangerous. And another is that it usually also won\u2019t trigger a response from your antivirus system, making it all the more treacherous. Some ransomware variants are even capable of disabling your antivirus software altogether. However, on some occasions it may in fact be possible to intercept a ransomware attack before it\u2019s over. In this case a significant system slowdown is usually what would give the infection away. And if you happen to notice an unfamiliar process using up all of your computer\u2019s CPU and RAM, shut your machine down immediately. The Usam file distribution The Usam file distribution can take place using a variety of different means, most commonly malvertisements and spam. And very commonly there\u2019s also a Trojan (Auto Refresh Malware, Wup.exe) or other backdoor virus aiding the Usam file distribution. So with that in mind, we would also recommend running a full system scan for additional malware after you have dealt with this variant. \u00a0 SUMMARY: Name Usam Type Ransomware Danger Level High\u00a0(Ransomware is\u00a0by far the worst threat you can encounter) Symptoms Very few and unnoticeable ones before the ransom notification comes up. Distribution Method From fake ads and fake system requests to spam emails and contagious web pages. Data Recovery Tool Not Available Detection Tool Remove Usam Ransomware Some of the steps will likely require you to exit the page. Bookmark it for later reference. Reboot in\u00a0Safe Mode\u00a0(use this guide if you don't know how to do it). WARNING! READ CAREFULLY BEFORE PROCEEDING! Press CTRL + SHIFT + ESC at the same time\u00a0and\u00a0go to the\u00a0Processes Tab. Try to determine which processes are dangerous.\u00a0 Right click on each of them\u00a0and select Open File Location. Then scan the files with our free online virus scanner: After you open their folder,\u00a0end the processes\u00a0that are infected, then delete their folders.\u00a0 Note:\u00a0If you are sure something is part of the infection - delete it, even if the scanner doesn't flag it. No anti-virus program can detect all infections. Hold the Start\u00a0Key\u00a0and\u00a0R\u00a0- \u00a0copy +\u00a0paste the following and click OK: notepad %windir%\/system32\/Drivers\/etc\/hosts A new\u00a0file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below: If there are suspicious IPs below "Localhost" -\u00a0write to us in the comments. Type msconfig in the search field and hit enter.\u00a0A\u00a0window will pop-up: Go in\u00a0Startup --->\u00a0Uncheck\u00a0entries that have "Unknown" as Manufacturer. \tPlease note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate. Type Regedit in the windows search field and press Enter.\u00a0Once inside, press CTRL and F together and type the virus's Name.\u00a0 Search for the ransomware\u00a0\u00a0in your registries and delete\u00a0the entries. Be extremely careful - \u00a0you can damage your system if you delete entries not related to the ransomware. Type each of the following in the Windows Search Field: \t%AppData% \t%LocalAppData% \t%ProgramData% \t%WinDir% \t%Temp% Delete everything in Temp. The rest just check out for anything recently added.\u00a0Remember to leave us a comment if you run into any trouble! \u00a0 How to Decrypt Usam files We have a comprehensive (and daily updated) guide on how to decrypt your files. Check it out here. If the guide doesn't help, download the\u00a0anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
