Information stealers in general

Usually, information stealers run silently in the background to avoid suspicion. They are used mainly to steal credit card details, login credentials (e.g., usernames, passwords), data saved in browsers, the clipboard, and other sensitive information. More examples of information-stealing malware are CockyGrabber, KurayStealer, and SaintStealer.

How did Growtopia infiltrate my computer?

Most cybercriminals distribute malware via emails (they send emails containing malicious links or attachments), cracked software download websites (and other unreliable sources), Trojans, and fake updating tools. Either way, users infect computers after they execute malware by themselves.

Most commonly used files for malware distribution are malicious documents (e.g., PDF, Microsoft Office documents), executable files, archive files (e.g., ZIP, RAR), and JavaScript files. Examples of untrustworthy sources that threat actors use to distribute malware are P2P networks, third-party downloaders, and various shady web pages.

How to avoid installation of malware?

Do not click links or open attachments in emails sent from suspicious addresses (especially if such emails are irrelevant). The sample applies to files downloaded from questionable sources. Download software (or files) from official pages and platforms and use direct links.

Keep the operating system and installed software up to date. Use tools provided by the official developers for updating and activating the installed software. 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.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

Delete malware in Autoruns

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.
