Okay boys and girls, I visited the Kaspersky.com web site (this is an anti-virus site) and found a list of malware. You can download a bunch of utilities to remove all sorts of malware. The TDSSKiller can remove the malware shown below + a few more. Also look over the list of other utilities given HERE. I didn't realize there are so many badguys out in cyberland to produce all this crapware. How do we win against this group? It feels like somebody shoved an ice pick in my ear (ou, I hate when that happens). It just seems like I have uncovered the tip of an iceberg and there is so much more crapware to discuss.


List of malicious programs:

Rootkit.Win32.TDSS
Rootkit.Win32.Stoned.d
Rootkit.Boot.Cidox.a
Rootkit.Boot.SST.a
Rootkit.Boot.Pihar.a,b,c
Rootkit.Boot.CPD.a

Trojan-Dropper.Boot.Niwa.a
Trojan-Ransom.Boot.Mbro.d,e
Trojan-Ransom.Boot.Siob.a
Trojan-Ransom.Boot.Mbro.f



So, let's look over these viures shown above. As you can see there are quite a few Rootkit viruses with different names. Rootkits were discussed in some detail starting with main page. The problem that I am having is how do I know which Rootkit invaded my computer so I can get the removal program from Kaspersky. The Rootkit doesn't announce which one is executing, in fact, It hides itself from the list of processes running. However, I think the TDSSKiller utility will fight quite a few of the Rootkits in the list above. How successful TDSSKiller will cleanse these viruses is not easy to determine as I am not going to infect my computer to find out. We'll have to trust Kaspersky since it appears they have addressed many type of infections.

The next type of virus is called a backdoor virus. What is a backdoor virus Mr Pctechnician? Well here is a definition:

"Backdoor threats increase when multiuser and networking operating systems are used by many organizations. In a login system, a backdoor used for system access may be in the form of a hard-coded username and password. A network administrator (NA) may intentionally create or install a backdoor program for troubleshooting or other official use. Hackers use backdoors to install malicious software (malware) files or programs, modify code or detect files and gain system and/or data access. Even backdoors installed by network administrators pose security risks because they provide a mechanism by which the system can be exploited if discovered."

The last two crapware entries (virus and trojan) are probably some of the original viruses that were unleashed on us a few ago.

"In computing, a Trojan horse, or Trojan, is any malicious computer program which misleads users of its true intent. The term is derived from the Ancient Greek story of the deceptive wooden horse that led to the fall of the city of Troy. Trojans are generally spread by some form of social engineering, for example where a user is duped into executing an e-mail attachment disguised to be unsuspicious, (e.g., a routine form to be filled in), or by clicking on some fake advertisement on social media or anywhere else . Although their payload can be anything, many modern forms act as a backdoor, contacting a controller which can then have unauthorized access to the affected computer. Trojans may allow an attacker to access users' personal information such as banking information, passwords, or personal identity (IP Address). It can infect other devices connected to the network. Ransomware attacks are often carried out using a Trojan. Unlike computer viruses and worms, Trojans generally do not attempt to inject themselves into other files or otherwise propagate themselves. "

This excerpt is from wikipedia an interesting aside:

Trojans may require interaction with a malicious controller (not necessarily distributing the Trojan) to fulfill their purpose. It is possible for those involved with Trojans to scan computers on a network to locate any with a Trojan installed, which the hacker can then control. Some Trojans take advantage of a security flaw in older versions of Internet Explorer and Google Chrome to use the host computer as an anonymizer proxy to effectively hide Internet usage, enabling the controller to use the Internet for illegal purposes while all potentially incriminating evidence indicates the infected computer or its IP address. The host's computer may or may not show the internet history of the sites viewed using the computer as a proxy. The first generation of anonymizer Trojan horses tended to leave their tracks in the page view histories of the host computer. Later generations of the Trojan tend to "cover" their tracks more efficiently. Several versions of Sub7 have been widely circulated in the US and Europe and became the most widely distributed examples of this type of Trojan. In German-speaking countries, spyware used or made by the government is sometimes called govware. Govware is typically a Trojan software used to intercept communications from the target computer. Some countries like Switzerland and Germany have a legal framework governing the use of such software. Examples of govware Trojans include the Swiss MiniPanzer and MegaPanzer and the German "state trojan" nicknamed R2D2. German govware works by exploiting security gaps unknown to the general public and accessing smartphone data before it becomes encrypted via other applications.

Due to the popularity of botnets among hackers and the availability of advertising services that permit authors to violate their users' privacy, Trojans are becoming more common. According to a survey conducted by BitDefender from January to June 2009, "Trojan-type malware is on the rise, accounting for 83-percent of the global malware detected in the world." Trojans have a relationship with worms, as they spread with the help given by worms and travel across the internet with them. BitDefender has stated that approximately 15% of computers are members of a botnet, usually recruited by a Trojan infection.
