System Requirements and Installation
Windows 7, Vista, Windows Server 2003 and XP computers can use ThreatFire. It will install a startup program Tftray.exe that runs in the notification area in Windows. ThreatFire runs as a service which is why you'll find Tfservice.exe processes. It is not recommended to disable the ThreatFire service because it is required when the program finds a nasty infection such as a rootkit infection.
ThreatFire will check the security protection installed on the computer and provide recommendations if the computer does not have antivirus, firewall, or antispyware programs. It will also run a quick scan for malware. Note that PC Tools does not recommend installing ThreatFire in a computer that is infected with malware.
A PC restart is required after installing ThreatFire so the drivers will be loaded and installed successfully. The program can register itself to Windows Security Center or Windows Action Center as an antivirus program but it is not necessary, unless you want to be notified by Windows Security Center on the status of ThreatFire.
ThreatFire installation will use up to 17.7MB of hard disk space and it is listed in Add and Remove Programs utility in Windows but the program will add its own uninstaller shortcut in the Start Menu, as well. An e-mail registration is not required before you can download, install or start using ThreatFire.
Note that installer of PC Tools ThreatFire is bundled with Google Toolbar which is not required to continue using ThreatFire. Uncheck the box to prevent installation of Google toolbar.
