What is a Computer Virus?
A computer virus is nothing more than a computer program which is able to replicate and attach itself to programs or files infecting the host without its knowledge.
Moreover, a computer virus can spread from one host to another like human viruses. The spreading is a result of sharing infecting files or downloading files from un-trusted sources.
Most of the viruses attach to executable files and their malicious operation begins when you run or open the executable file. In other words, a virus does not infect your computer unless you execute the infected program.
Not all viruses cause catastrophic effects. Some of them cause only disturbing effects while others can damage your software or even cause total hardware failure.

What's a Spyware ?
As its name suggests, Spyware is a software that stealthily collects an Internet user’s personal information without his permission.
The “personal information” used in the paragraph above has wide connotations and the term includes:
- grabbing Internet browsing habits,
- spying on the user’s documents that are stored in his hard disk and
- stealing the user’s passwords.
A Spyware’s intent can be harmless – it can record a user’s web activity and use that information by displaying targeted (but unwelcome) advertisements on the user’s computer. On the other hand, a Spyware’s intent can be criminal – it can be used to steal passwords and other sensitive information such as credit card numbers.
Spyware is not a virus. A virus damages the computer’s functioning and proliferates, while Spyware gathers information.
Microsoft’s Internet Explorer is an all time Spyware-favorite as Spyware makers keep exploiting Internet Explorer’s security holes and keep installing software on user’s of Internet explorer without the user being aware of such installation/s. Microsoft keeps coming out with new patches all the time and it is advisable to patch up your Internet Explorer (if you are using it).
If you have Spyware installed on your computer you will most probably come across increased CPU activity and extra hard disk usage, which will make your computer operate at sub-optimal levels.
