Small.CA aims to infect computers with Windows OS

Small.CA virus is categorized as a trojan

Small.CA virus belongs to the category of trojans that are designed to work as backdoors to infiltrate malware, and monitor user's browsing behavior or steal valuable data from the computer. Usually, this type of malicious program detects system vulnerabilities and exploits them to help hackers distribute high-risk PC infections.  

According to the reports, Small.CA spreads via rogue ads promoted on suspicious websites, bundled with free applications or malvertising campaigns. After successful infiltration, it alters Windows Registry[1] by assigning the command to automatically launch itself every time the user turns on the computer. As a result, victims might have no clue that the malicious program is operating on their systems for months or even years. 

Experts warn that you can unconsciously infect your system with the trojan if you:

  • Visit suspicious websites and click on ads that it displays;
  • Do not use anti-malware programs or forget to update them regularly;
  • Download video, audio, and other files illegally;
  • Open spam e-mail attachments that are sent by unknown senders.

You should always use a sturdy security software to avoid trojans. However, if you have already been infected, remove Small.CA virus with the help of Reimage or Malwarebytes Anti Malware. It will identify the executable files and quickly eliminate them. Even if you think that you are virus-free, you should keep in mind that IT security experts, like the ones working for DieViren.de,[2] warn users that trojans are able to sneak into systems without users' knowledge by imitating regular OS processes.

If you delay Win32/Small.CA removal, the consequences might be harmful not only to your computer but to yourself as well. It might deteriorate your browsing experience by generating annoying and malicious ads that pop-up every time you open your browser. There is a high possibility that they may cause redirects to less than reliable sites that are used to distribute spyware, ransomware, etc.

Besides, criminals created Small.CA to make illegal profits from inexperienced computer users. They set the trojan to collect files with specific file extensions that might possibly contain valuable data and send it to the hackers. Later, the stolen files may be sold in the underground market or misused in another way. 

Also, there is a risk to lose your social media accounts or online banking passwords since the trojan hijacks your browser and infiltrates tracking cookies or extensions to monitor your browsing behavior. In other terms, developers of Small.CA are able to view anything you submit while surfing the internet.

Trojan works as a 5-stage malware

Small.CA trojan horse is a perfect tool for cybercriminals and programmed to do its job following five steps:

  1. Successfully infiltrate on the targeted computer;
  2. Use Command Prompt to register itself as a legitimate process;
  3. Modify Windows Registry settings to enable an autostart;
  4. Wait for a remote command from the hacker;
  5. Infiltrate specific malware and/or collect credentials, other vital data.

You should follow safe browsing rules to avoid the infiltration of the malware

Typically, Small.CA virus spreads on the malicious websites as deceptive advertisements. Be aware that they appear in any form, such as banners, pop-ups, in-texts, etc. Developers make considerable investments to make their ads look genuine and attract as many gullible people as possible to click on them. Thus, to avoid Win32/Small.CA, you should stay away from any types of advertisements despite their legitimate appearance. 

Moreover, do not open questionable e-mails sent by people or companies that you don't know. Hackers use malspam campaigns[3] to distribute the trojan. Usually, it might appear as a fake invoice or another document from an authorized institution and contains a malicious link or attachment. You shouldn't open it under any circumstances if you want to protect your computer from Small.CA.

Employ a powerful security software to eliminate Win32/Small.CA

If you suspect that your PC might be infected, download a reliable security software right away. It is extremely important to do it as soon as possible since trojan might infiltrate numerous other viruses and damage your computer permanently. 

After a successful installation of an anti-malware program, let it scan your system and remove Win32/Small.CA virus immediately. Be aware that eliminating might require specific IT knowledge. Thus do not try to get rid of it by yourself.
