Covid virus removal guide
What is the Covid stealer?
Covid is the name of a piece of malicious software, classified as a stealer. As the classification implies, this malware is designed to steal information. Stealers can employ a variety of functionalities to stealthily obtain data from infected systems. The Covid malware is deemed to be highly dangerous; hence, its infections must be eliminated immediately upon detection.
Typically, the primary functionality of stealers is extraction and exfiltration of information from certain browsers and other specific applications. From targeted browsers, these malicious programs can steal browsing and search engine histories, browser cookies, autofill data and stored log-in credentials (i.e. IDs, usernames and passwords). Other applications are similarly targeted for the log-in credentials that they store. Cyber criminals mainly attempt to extract the usernames/passwords of email, social media, social networking, messenger, data storage and transferring, e-commerce, online money transferring, cryptocurrency wallet, e-wallet, and banking accounts. Through hijacked communication/social accounts, criminals can ask contacts/friends for loans and/or proliferate malware (by sharing infectious files) - under the guise of the genuine owner. Accounts that directly or indirectly deal with financial information (e.g. banking account and/or credit card details) are of particular interest, as they can be used to make fraudulent transactions and/or online purchases. Some stealer-type malware has keylogging features. In other words, these stealers can record key strokes. This endangers the privacy of any and all typed information. These malicious programs may also be able to exfiltrate (i.e. download) content stored on the compromised device. If the stolen files are especially sensitive and/or compromised - they may be held for ransom, under threat of publication and/or sale to the victims' competitors. To summarize, Covid stealer infections can result in severe privacy issues, financial losses and even identity theft. If it is suspected or known that the Covid stealer (or other malware) has already infected the system - an anti-virus must be used to remove it without delay.
|Threat Type||Trojan, password-stealing virus, banking malware, spyware.|
|Detection Names||Avast (Win32:Malware-gen), BitDefenderTheta (AI:Packer.96A8F2121F), ESET-NOD32 (A Variant Of Win32/Injector.CUWJ), DrWeb (Trojan.Siggen10.22087), Full List (VirusTotal)|
|Symptoms||Trojans are designed to stealthily infiltrate the victim's computer and remain silent, and thus no particular symptoms are clearly visible on an infected machine.|
|Distribution methods||Infected email attachments, malicious online advertisements, social engineering, software 'cracks'.|
|Damage||Stolen passwords and banking information, identity theft, the victim's computer added to a botnet.|
|Malware Removal (Windows)||
To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
Anubis, Babax, StormKitty, Taurus and XTMEM are some examples of other stealers. Malware can have a broad range of malicious functionalities and these features can be in varied combinations. Popular types include (but are not limited to): information stealers, loader/backdoor trojans (capable of causing chain infections), spyware, ransomware (capable of encrypting data and/or locking the screen for ransom purposes), cryptominers (capable of using system resources to mine cryptocurrency), keyloggers, and so on. Regardless of how malicious programs operate, the end-goal is always the same - to generate revenue for the cyber criminals using them.

How to avoid installation of malware?
Suspicious and/or irrelevant emails must not be opened, especially any links or attachments present in them - as that can lead to system infections. It is advised to only download from official and trustworthy sources. Additionally, all products must be activated and updated using tools/functions provided by legitimate developers. Since illegal activation tools ("cracks") and third party updaters are often employed to spread malware. To protect device integrity and user privacy, it is paramount to have a dependable anti-virus/anti-spyware suite installed. Furthermore, this software must be kept up-to-date, used to perform regular system scans and to remove detected/potential threats and issues. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
