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 FortectIntego or Malwarebytes. 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.
Small.CA virus can collect valuable information from victim's computer and send it to hackers. 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:
Successfully infiltrate on the targeted computer;
Use Command Prompt to register itself as a legitimate process;
Modify Windows Registry settings to enable an autostart;
Wait for a remote command from the hacker;
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.

If you want to get rid of Small.CA trojan, reboot your computer to Safe Mode with Networking. If you don't know how to do that, the guidelines provided below will help you:
Important! → Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.
Step 1. Access Safe Mode with Networking
Manual malware removal should be best performed in the Safe Mode environment.

How to prevent from getting trojans
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
