I have a HP Pavilion with Microsoft Windows Vista Home Premium 32-Bit. I use CA Security Center as my anti-virus protection and in a recent scan it has shown that GROKSTER has infected my computer. I have researched the program and found that it is a tracker and can take my information. I have not been able to remove the files even though the program does not exist in my control panel add/remove programs screen. Any help would be greatly appreciated. I really want to get rid of this. Thanks in advance.
