A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.
