antivirus on the downloaded file. Do not rely on MSWindows, Internet explorer, or on the electronic signature: a unsigned download is usually as safe as a signed one, signed just means the author paid Microsoft or Verisign for a stamp, it does not mean verified. Please kindly

Principal AntiVirus protects your computer against viruses, trojans, worms, backdoors, spyware, adware and other malware. It does not use signature scanners, requires no regular updates and protects against both future as well as current malware. Principal AntiVirus is faster and more efficient than other antivirus software because it remains in a dormant state and does not come into action until a dangerous event is triggered.
(
Protect yourself against viruses and malware without signature scanners)

Principal AntiVirus is powerful antivirus software which protects your Windows computer against a large range of threats including viruses, worms, trojans, backdoors, adware, spyware and other malware.
It is designed to offer you principal protection against currently known as well as future viruses and malware without the need for regular updates or signature scanners. It intercepts threats before they become active without constantly having to check all incoming and outgoing data against known virus footprints.
The way the program works is by scrutinizing dangerous programs that start for the first time. Before a dangerous program causes damage to your computer, Principal AntiVirus will block it and tell you how bad is the program you are running and gives you advice. On request you will
receive a detailed motivation why a running program is thought to be a virus, worm, trojan, backdoor or other malware. If you are deliberately running some dangerous program you tell Principal AntiVirus to trust it forever.
Principal AntiVirus is faster and more efficient than other virus software because it remains in a dormant state and does not come into action until a dangerous event is triggered.
Principal AntiVirus works on Windows XP, 2003 and 2000.
