PWSteal.Karagany.C is a new Windows systems attacking infection, which is also known by alias names of PWS:Win32/Karagany.C, Adware/LiveSecuritySuite, Reveton and Trojan-Ransom.Win32.Gimemo. What is most notable about the devious application is the fact that this deceptive ransomware program can initiate the infiltration of such widely spread infections as FBI Moneypak, Metropolitan Police Virus, Cybercrime Investigation Department virus and a great number of other infections that have been attacking computers across North America and Europe. The main stealthy Trojan’s task is to drop malware into your system, so that cyber criminals would have enough control and be able to utilize your Windows from malicious infections’ propagation or illegal, surreptitious profiting. Since this infection does not have an interface and its processes are highly surreptitious it might be very difficult for you to discover and remove PWSteal.Karagany.C. This is a serious issue, because even if you manage to delete threats downloaded by this devious Trojan, you could completely miss its own running.

Multiple PWSteal.Karagany.C components are supported by rootkit and polymorphic features, which could also make it impossible for you to detect and remove the entire Trojan. Atapi.sys is one of the rootkit components, which is also capable of affecting most popular Internet browsers, including Google Chrome, Internet Explorer and Mozilla Firefox. The name of this malignant file actually belongs to an original Microsoft’s Standard IDE/ESDI Hard Disk Controller system, both of which could be found under C:\WINDOWS\system32\drivers\atapi.sys. This means that the devious Trojan’s component could modify an original file; therefore, even if you locate it, do not rush to remove it! The file can create additional processes, initiate background services, delete original processes, and it might be found in your system as 50896389.SYS, or under other randomly generated names. UpgradeHelper.exe, found in the Application Data folder, is another PWSteal.Karagany.C component, and upgradechecker.exe, upgrade.exe or validator.exe are a few of its alias names. This file can delete and add registry products, change system’s startup processes, tamper with temporary components, remove the safe mode feature, reconfigure Windows Security Center and release fake notifications.

All PWSteal.Karagany.C processes are meant to help additional malware to enter your system and take advantage of various system vulnerabilities, so you should take care of your system’s security right away and have the malicious Trojan removed. Since it might be superbly difficult to delete PWSteal.Karagany.C manually, inexperienced Windows users with little knowledge about malware removal should stick to the protection provided by legal security tools, which will be able to delete the infection automatically.
