How does spyware get on my computer?

[eyesontech]

There are several techniques. Sometimes they arrive as an automatic download from a website you are surfing. Typically this happens a lot on porn sites. Sometimes if you download a free or illegal piece of software, they are embedded in the installation process. Or spyware can get on your computer via an email attachment that you shouldn't have opened.

any more ideas?

From the internet they come in along with the data from the websites as no all websites are trustworthy . Some of the more malicious programs install themselves by exploiting security holes in Internet Explorer. Regardless, these programs are most often installed without your consent and knowledge.While some spyware is installed with the user's knowledge (although the user may not understand exactly what he/she has done), much of the time it is installed surreptitiously as part of another program installation.
