Spyware Guard

Spyware Guard from Javacool Software is a free program which performs real-time scans to catch and block spyware, browser-hijackers and prevent malware from downloading while surfing with Internet Explorer. It provides automatic signature updates with its SG LiveUpdate feature and has fair logging and reporting capabilities. The program is small in size, but seems to consume a disproportionate amount of system resources on some computers and may not be worth the impact to your PC.
