Using and maintance of anti-spyware-yuckware.

Spyware removers
AdAware SE and Spybot S & D are good, I'd also recommend PestPatrol.
You need to update once a week, its necessary because. although you don't download, most sites you visit will put some form of cookie on your computer, some of these will contain spyware. I'd advise running these programs after every browsing session, or at least once a day, if you access the web daily, and always run them to check anything you do download. You don't mention if you have a firewall, this will help protect you while you are connected to the internet, I'd recommend Zone Alarm, if you are running XP the firewall included is not as good as Zone Alarm, even Microsoft admit this is true! So install ZA and disable XP's firewall, instructions can be found at ZA's site.
Hope this is useful.

that is very helpful.Thank you
I have Mcafee firewall and yeah, it sucks .
Even with it i had gotten a trojan and a few other things.
So i dont rely on it at all.
I can find zone alarm by just going to zonealarm.com? Right ? Or is it on majorgeek or some other web site?

Spyware removal
You'll find ZoneAlarm at www.zonelabs.com. You can also find it through a search at www.download.com.
Glad to have been of assistance.
