When your computer is infected with spyware how do you find the source of swpyware and then hack into that persons computer and give them spyware?

Spyware generally comes from an infected file you have downloaded, not a specific person, so when you download something make sure you scan it with a trusted anti virus software such as Norton, AVG or Avast. Also, when you install a programme, make sure you read the licence agreement and all other small print, to see if it mentions installing anything else alongside the main programme.

You shouldent have any problems with spyware if you download from trusted sources and scan your files before opening.

As far as hacking goes, hacking takes a long time to master (and is also illegal, may i add).

Why does my computer freeze when going to certain websites?

It is probably because those websites are too big for your Internet connection to open, so the Internet would take a long time to load them. Thus if you try and click it a lot of times or it takes too long to load, then this can cause the website to not respond. Then your computer freezes as the website does. Perhaps because your computer has too many programs open as well. Try closing most of the other programs and websites, then try reloading the site.

If the above advice fails, then your browser could be corrupt, and/or you could have malware installed. The first thing you can try is go to Add/Remove programs and remove any unfamiliar software that didn't come with the computer, particularly if it is recent. Uninstall any toolbars, unfamiliar games, plugins, shopping helpers, web helpers, etc. Then check your browser settings for toolbars, plugins, or other add-ons and remove any that are unfamiliar or suspicious. After that, run anti-spyware and anti-malware programs. Then if that doesn't fix things, then try reinstalling the browser. If the problem is in IE, then get the IE installer from Microsoft or try one of the IE repair programs.

If you still have problems, then you may need to remove and reinstall web support programs such as JAVA, Shockwave, Adobe Flash, Adobe Reader, etc. If the sites involved are multimedia sites, then you might need to install or reinstall a codec pack. Good codec packs will scan for multimedia errors, possibly re-register any corrupt or missing multimedia registry keys, and check for incompatible multimedia files, all as a part of installing.

How can you optimize your computers performance?

If your computer is running very slow, there can be a few different things wrong with it. The first thing to do is to delete your temporary internet files. Next is to run a disk cleanup. After that, a malware detection program should be run to detect any malware or spyware. After that, download any operating system updates. If the computer is still running slow, try to pinpoint a specific program which may be causing the computer to run slow and disable it from startup or remove it completely. The computer should then be defragmented to optimize the file allocation table. Random access memory can be upgraded to enable programs to run a bit faster. If none of this works, the final fix is to re-install the operating system. See the link below for a detailed description of how to optimize your PC.

Why is the key board the most common input device?

On a QWERTY keyboard, the keys have been placed strategically so that the majority of words can be typed with two hands rather than one.

This means that the hands will not constantly cross over each other, block each other or bump each other, which speeds up the typing.

QWERTY first appeared on typewriters. The first typewriters had letters in alphabetical order, which, when the keys were pressed, often caused jamming and clashing. So QWERTY was very carefully invented, so the complicated typebars in typewriters didn't clash.

This invention made typewriters easier and faster to type on with minimal jamming. With the invention of the computer keyboard, QWERTY is used for similar reasons, although the ink typebars are removed completely on keyboards - speed and to avoid your hands running into each other.
