There are so many innovative ways that hackers come up with in order to successfully
access each and every computer available, plant malicious software, and eventually do their dirty deeds. Unless your computer is protected by an antivirus firewall software program, it will be easy for hackers to do those.
Probably the main reason hackers change their ways of attacking and sending malware is the fact that not all computer users are knowledgeable enough regarding things related to computer hardware, software, and so on. Another reason is that many computer users do not know how to protect their systems with antivirus firewall software.
A relatively new method of attacking is called drive-by-downloading wherein a web application that has been compromised is instructed through the web browser to install or download malicious software found within the hacker's server. The computer user may not notice these activities. The malicious software is usually a Trojan horse that controls the systems of the victim's computer.
This type of attack usually requires the hacker to put another HTML code to the application. If the HTML code is used by the browser, then the code automatically downloads the malicious software into the innocent computer user's machine. Usually this kind of attack is in the form of a pop up window that features an optional button for you to cancel the operation. This specific button may be the trigger for the malicious software to be downloaded. Again, this activity may eventually go unnoticed by the innocent computer user.
That is why it is necessary to know the signs of these drive-by-downloads. Early detection and prevention of possible malicious software trying to access your machine are always the best way to go.
Tampering of your web applications can be avoided if you have software that detects any infectious software that may try to breech your system. It is best to have the latest antivirus software that has a firewall, and anti spyware and other features that can help you protect your system from any malicious software.
It is advisable to always update your software because knew breeds of malware are being developed quite frequently and are ready to attack. Your antivirus firewall software should have the real-time scanning feature that will detect possible tampering of your application and it should frequently updated also. Due to so many types of malicious softwares out in the web it is better to be always on guard and updated. Being aware and ready to new kinds of cyber crimes is an ace on your part.
