Worm.Cacfu.A can infiltrate any unprotected Windows system, and then can replicate itself for a number of times in computer’s and removable drives, which might allow infection’s spreading to additional machines. Traveling from one computer to another, this worm is most likely to infect Windows users in China, US, Japan and India areas, but that does not mean that system’s outside these countries will not get infected with the vicious malware. Nonetheless, even if this worm does not have an interface, its files are the telltale components, which could alarm you of this infection’s existence. Aside from that, you should also beware of slower system’s performance speeds or removed access to some Windows components, which would immediately signal an infection. If you are having problems with detecting the dangerous application, read this report carefully to find out how you can detect and remove Worm.Cacfu.A in no time.

It is now known that the infectious worm manages to control Windows systems with two dangerous executable files missAU.exe and SocksA.exe. However, Worm.Cacfu.A may also present itself with tel.xls.exe and autorun.inf components, which may be found in infected system’s drives. These files might be employed to successfully control worm’s contagion, but it is the two executables that can cause most damage to your system and personal files. MissAU.exe can add, delete and hijack processes, modify Windows File Protection, so that malignant processes are not discovered, and implement wininet.dll to record online browsing habits. SocksA.exe complements the missAU.exe features, but can control your system even more, by having your keyboard inputs recorded, processes deleted, safe mode and Windows Security Center features disabled, and administrative rights to Windows tools Registry Editor and Task Manager removed. This also helps the rogue to stay hidden from removal! Moreover, this executable reconfigures Physical Memory Protection settings, allowing remote servers to record personal and technical data, found in your Windows OS.

Worm.Cacfu.A can be gravely harmful to your personal data, if this infection manages to record your passwords and use them to your disadvantage. And because of restricted access to Windows tools, it will be extremely complex to delete the infection’s components from your system manually. This is why it is best if you install legal security software as soon as possible, and let up-to-date features find and delete Worm.Cacfu.A neatly and quickly. If you are hesitant to spend your money on security applications, remember that this investment is likely to pay off quicker than you think, with more and more dangerous infections created to infiltrate unprotected Windows systems.
