What kind of malware is Zaraza?
Zaraza is the name of a stealer-type malware. Programs within this classification operate by extracting (stealing) information from infected systems and installed applications. Stealers can target specific details or a broad range of data. Regardless, malware like Zaraza poses serious threats to user privacy.
Zaraza malware overview
Typically, following infiltration, malware begins collecting relevant device data, e.g., operating system version, hardware details, device name, user account name, IP addresses (geolocations), and so on.
As previously mentioned, stealers like Zaraza can obtain data from the system and/or the software installed on it. This malware is often capable of downloading system and user files.
Information of interest can include: browsing activity, Internet cookies, log-in credentials (IDs, usernames, email addresses, passwords, passphrases, etc.), personally identifiable details, finance-related data, credit card numbers, and so forth. The collected information can be sold to third-parties or otherwise abused for profit.
It is pertinent to mention that stealer-type malware may have other functionalities as well. Furthermore, malware developers often improve upon their creations – hence, future iterations can have additional/different features (more information on new Zaraza variants below).
To summarize, the presence of software like Zaraza on devices can result in severe privacy issues, significant financial losses, and even identity theft.
If you suspect that your device is infected with the Zaraza stealer (or other malware) – immediately use an anti-virus to eliminate it.

Stealer-type malware examples
Malware can have various capabilities, which can be in different combinations. However, regardless of how malware operates – its presence on a system endangers device integrity and user safety. Therefore, all threats must be removed immediately upon detection.
How did Zaraza infiltrate my computer?
Malware is primarily spread using phishing and social engineering techniques. Malicious software is typically disguised as or bundled with ordinary programs/media.
The most widely used proliferation methods include: drive-by (stealthy/deceptive) downloads, online scams, malicious attachments and links in spam emails/messages, malvertising, untrustworthy download channels (e.g., freeware and third-party sites, P2P sharing networks, etc.), illegal software activation tools ("cracks"), and fake updates.
Furthermore, some malicious programs can self-spread via local networks and removable storage devices (e.g., external hard drives, USB flash drives, etc.).
How to avoid installation of malware?
We strongly recommend being cautious while browsing since fraudulent and malicious online content usually appears legitimate and harmless. We advise against opening the attachments or links found in suspicious/irrelevant emails and other messages, as they can be infectious.
Another recommendation is to download only from official and verified sources. We also advise activating and updating software using functions/tools provided by genuine developers, as illegal activation ("cracking") tools and third-party updaters can contain malware.
We must emphasize the importance of having a reputable anti-virus installed and kept up-to-date. Security programs must be used to run regular system scans and to eliminate detected threats and issues. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus 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 Combo Cleaner Antivirus 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 Combo Cleaner Antivirus for Windows.
