The probable reasons that makes a PC vulnerable


The probability of flaws take place because of large, complex systems. These systems also increase the chance of unintended access points.

Website Browsing through Internet: As we all know some websites contains harmful spyware or adware. When one visits those sites these Spyware or Adware automatically installed on the computer systems and infected the pc. This infection also results in passing of personal information to third party individuals.
Using same software, well-known code, operating systems, or hardware increases the chance of an attack in order to exploit the flaw. Since a program has the access to the saved password, and between many programs and websites users re-uses the password there always a chance of being discovered by brute force. Thus a weak password has the more chances of being discovered.
When a software program has been created, the programmer leaves an exploitable bug in that software. These bugs sometimes allow misuse on an application by an attacker.
