ContraVirus is a roguespyware application that poses as a legitimate anti-spyware program.[1] The application uses a false scanner to force computer users to pay for the removal of non-existent spyware items. It may also be known as ExpertAntivirus.[2][3]
ContraVirus may be downloaded as a trojan horse, along with possible other software. Typically, it may be installed by the SmitFraud trojan.[4]
Symptoms of infectionedit
ContraVirus has been known to display fake messages stating that a user's computer is infected with spyware. It may also install the file wincom27.dll, located in C:\WINDOWS\ and ext32inc.dll located in C:\WINDOWS\system\, in order to persuade a user to purchase the software.[5] Traditionally, a user will see Contravirus running a "scan" of their computer, at which time a user will be prompted to purchase the Contravirus software in order to remove the threat. It may also hijack the user's browser and install a toolbar.[6]
The removal of Contravirus is difficult and may require assistance from qualified IT Support Personnel. However, users have had success removing the program using the SmitFraudFix.zip program, as well as known programs such as Kaspersky Anti-Virus, Spybot Search & Destroy, and the Norton Family of Security products.
