"The best spyware software available on the market"4.5 starson by MattyMustng
Pros: Catches nearly everything; interface is extremely easy; does not cause the system to lag; fast start up and great options
Cons: Webroot does not provide a Suite for firewall, anti-virus, adware, spyware, etc., one year subscription
Summary: This is by far the single best spyware detection and scanner on the market. I recently got a malicious virus on my computer (of which ZoneAlarm, Norton, and Ad Aware could neither stop or detect). I went out and purchased Webroot for a fair price of $20, and used it. Within 15 minutes the virus (trojan) had been removed and my PC was back to the normal, perfect state. Not to mention, Spy Sweeper has one of the easiest interfaces I have ever seen for novice users, and its start up is quick and it runs in the background with little harm to system resources. I only say it removes "nearly" all malware simply because I haven't encountered all malware in existence so I cannot vouch one way or the other. However, I have never had a problem with it. The only disadvantages are (a) the package is a one year subscription only (b) there is no suite available (such as PC-cillin 2006, which I also highly recommend) (c) there is no functional trial version available, although Cnet's download.com provides a free scan using this software, but nothing can be removed.
