In June 2012, numerous cases of infection of office computers were recorded. The cause was a malicious program classified as Trojan. Milicenso. The first mention of this virus dates back to 2010.
Anti-virus experts believe that the disabling of printing devices is a side effect of virus software. The main goal of this program is to distribute advertising content in the form of spam. Once infected with malware, the computer sends commands to all available printers. At the same time, the devices give out sheets with a meaningless set of characters until the paper runs out.
To combat such viruses, a whole range of measures should be taken. First, turn off your computer. Disconnect the printer cable. If the PC is connected to a network or the Internet, remove the appropriate cable from the socket. Turn on your computer again. Perform a full system scan with an anti-virus program already installed. Verify that there are no symptoms of infection by connecting the printer to your computer. Remove most of the paper from the compartment first.
If the scan with the used anti-virus did not help to remove the malware, download the Dr. Web CureIt program. Better to download from the official developer site. Use any uninfected computer or laptop for this. It is important to note that Dr. Web CureIt is free for home use only.
Run the application file from an external drive. Press the F9 button and select the program operation mode. Now click the "Start" button and wait for the scan to complete. Be sure to delete all found virus objects.
Reboot your computer. Connect a printer and an Internet cable to it. Check the operation of the printing device. Do not activate your Internet connection until you are sure that there are no traces of virus files.
