Jeefo virus removal guide
What is Jeefo?
Jeefo is malware that infects Windows executable files (.exe extension) by injecting them with malicious code. It is possible that cyber criminals behind this malware use Jeefo to collect sensitive information (usernames, passwords, credit card details) or for other malicious purposes. Therefore, it this malware is installed on the operating system, it should be eliminated immediately.
Cyber criminals commonly use malware such as Jeefo to inject malicious code into Windows executable, or other, files to steal sensitive information such as login credentials, credit card details, and other entered/saved data. Typically, they misuse the information to make fraudulent purchases and transactions, steal personal accounts (such as email, social media, banking), etc. Users with computers infected by such malware might become victims of identity theft, suffer monetary loss, lose access to various personal accounts, experience problems relating to online privacy, browsing safety, etc. Additionally, Jeefo could be used to stop legitimate processes from running. For example, prevent installed antivirus programs from detecting it. Jeefo might also be used to perform certain actions on the operating system such as, for example, to restart it, shut it down, or even run commands to infect the system with other malware. Therefore remove all malware including Jeefo from your computer immediately.

How to avoid installation of malware
All software should be downloaded from official websites and via direct links. Third party downloaders and installers, torrent clients, eMule (and other Peer-to-Peer networks), unofficial pages, etc., should never be used, they are used by cyber criminals to distribute malicious files/programs. Attachments and websites links in irrelevant emails that are received from unknown, suspicious addresses should not be opened, since they can cause installation of malware or other damage. Installed programs and operating systems must be activated and updated with tools/implemented functions provided by official developers. Furthermore, it is illegal to activate licensed programs with 'cracking' tools (unofficial activators). Operating systems should be regularly scanned for threats with reputable antivirus or anti-spyware software, which should be kept up to date. 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.

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.
