Trojans are the main culprit for recent spyware and malware infections.
Reports and studies have confirmed that most malware comes from Trojan infections or Trojan files instead of other means. Trojans make up the main cause for the installation of malware or rogue anti-spyware programs on PC's. BitDefender, a security vender, claimed that 80 percent of malware that infected computers worldwide came from a form of a Trojan on a computer. We know from our many parasite removal guides that malware comes in deferent forms that perform many malicious functions. In some cases it is not the Trojan that steals your personal information or create popups. It is usually the malware that is installed from a Trojan.
Malware may not be very difficult to remove in some situations compared to a Trojan infection. The Trojan that originally installed the malware may hang out on your system and further infect your computer after you remove or attempt to remove any malware. Because Trojans, for the most part, do not actively run process or stand out in the crowd as much as malware, it can go undetected for a long time.
Did you ever think that you completely removed a malware infection or rogue anti-spyware program and the next time you rebooted your system it came back? That's a common case if you have a Trojan residing on your system and it is not completely removed.
Websites that run scripts and file downloads such as video codecs are a common ways that a Trojan may enter into your system. Adobe Flash ActiveScripts is a familiar form of a script that can spread a Trojan especially with the many flash based websites found on the internet today.
Hackers wish to make money any way that they can. Trojan infections are becoming more dangerous and are starting to sneak more malicious files or software onto computers all over the world.
