Like when a spam email has a link and you click the link and it takes you to some pharmacy website. Is that more so just junk trying to get you to buy crap? Or is the link going to put spyware and virus on your computer? I use limited user account so I can’t download/run anything without first using my admin password.
so how does the trojan part work in spam? Wouldn’yt you have to download something?
interestingly that the 2nd and 3rd respondents here are trying to seel antispyware product rather than answer my question


Stopping spyware (‘malware’) is more than a one-time inoculation, folks.
This is about a weekly habit of cleaning ‘nasty dust bunnies’
from your personal computer.
In much the same way you clean your home with your favorite broom
and your favorite cleaning solvents, you will also need good tools
to clean spyware out of your PC.

Most is just getting you to buy junk, but some are for trojans
In response to the emergence of spyware, a small industry has sprung up dealing in anti-spyware software. Running anti-spyware software has become a widely recognized element of computer security practices for computers, especially those running Microsoft Windows. A number of jurisdictions have passed anti-spyware laws, which usually target any software that is surreptitiously installed to control a user’s computer. The US Federal Trade Commission has placed on the Internet a page of advice to consumers about how to lower the risk of spyware infection,
including a list of "do’s" and "don’ts."
