Does your computer seem sick? Malicious software may be to blame.
This malicious software may be in the form of a virus, adware or spyware. Many users are not really interested in the actual difference between them – the mere fact that they can wreak havoc on your system and result in anything from poor performance to a complete computer failure is enough to know they need to be avoided!
What is a virus?
A virus is a program that gets loaded onto your computer without you knowing about it and can potentially cause your PC to stop functioning and even result in data loss.
What is spyware?
Spyware and adware are different to computer virus because they do not create copies of themselves and spread, nor do they result in data loss. The most common symptom of a spyware is that your computer will start to run very slowly and have trouble connecting to the internet.
What is adware?
Adware is usually loaded onto your PC when you download or install a free program. Many free programs are provided free because they rely on the built-in advertising to generate sales.
