Stealer-type malware examples
More examples of malware that is designed and used by cyber criminals to steal sensitive data are Mist, VikroStealer and TroyStealer. Commonly, software of this type is capable of evading detection and can run stealthily in the system background.
Therefore, victims are often unaware that a computer is infected until some damage is done (such as fraudulent purchases/transactions).
How did CollectorStealer infiltrate my computer?
Typically, malware is distributed via spam campaigns, fake software updaters, untrusted software download channels, unofficial software activators and Trojans. Cyber criminals often attempt to deceive users into installing malware on computers by sending emails that include malicious attachments (or website links that download malicious files).
Unofficial, fake updaters infect operating systems by installing malware rather than updating installed programs, or by exploiting bugs/flaws of outdated software. Untrusted software download channels such as unofficial web pages, Peer-to-Peer networks (torrent clients, eMule), various free file hosting, and so on, are often used to distribute malicious files.
In most cases, the files are disguised as legitimate and regular. When downloaded and opened, however, they cause installation of high-risk malware. Software 'cracking' tools (third party activators) supposedly illegally activate paid software free of charge, however, rather than activating any software, these tools can install malicious software.
Trojans are programs that often proliferate other malware. If a malicious program of this type is installed on the operating system, it is very likely that it will install other, similar software.
How to avoid installation of malware
Do not open a files or website links that are attached to irrelevant emails, especially if the emails are received from unknown, suspicious addresses. Software and files should be downloaded only from official websites and via direct links. The other sources/tools mentioned above can distribute malicious files and software.
Installed programs must be updated and activated only with implemented functions/tools provided by official software developers. Furthermore, it is illegal to activate software with unofficial ('cracking') tools. Have a reputable anti-spyware or antivirus suite installed on the operating system and use it regularly for scans.
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.
