Newbie question. I am setting up an old Thinkpad running XP SP2. I first installed Panda Cloud and Spybot, and my next step was to install ZoneAlarm. However, Spybot halted the ZoneAlarm installation warning that the ZoneAlarm download file contained spyware, and that I should definitely not proceed with the install. Is this a known false positive? Is it safe to install? Is it possible that I somehow downloaded an infected ZoneAlarm install file?
