Antivirus & antispyware must be the sameware
Every network client must have antivirus software. We've been told so for years. Network admission and integrity control are poised to enforce it today in enterrprise networks and hopefully soon for public Internet access as well. Concern over spyware is increasing so rapidly that I fully expect that antispyware, too, will be a prerequisite for network logon. If we instrument poorly, network admission will end up like the queues at customs and immigration services: long, slow, tedious, and frustrating. More...
What is a Blended Threat?
In every Hollywood action movie, the action hero is a formidable adversary: adept in martial arts, an expert with explosives, a brilliant hit-and-run tactician, adept with every weapon imaginable.

It's not your imagination; it's a blended threat. Blended threat is a popular term for a multi-pronged attack against networked computers. More...
419 scams still arrive by postal mail
You may be familiar with 419 (alias Nigerian) scam emails. Fake lottery notifications, investment opportunities or advanced fee frauds are all examples of 419 scams, named after the Nigerian criminal code used to prosecute apprehended fraudsters. You may be surprised to learn that 419 scams still arrive by postal mail. More...
419 scams: the more you know
419 scams all pose a common proposition. Someone you don't know promises you a large sum of money. All you need to do is temporarily handle a small processing or facilitation fee in advance to release so that it will be possible to deliver a much larger sum to you shortly. But there is no large sum of money waiting for you, no matter what you may be told. More...
Viruses spread by email, removable media, network file shares and malicious web pages. If you do not have continuously running and routinely updated antivirus software installed, you are part of the problem. Not having anti-virus software is like not having renter's insurance if you are an apartment finder or car insurance if you drive- the software is a basic part of having a computer or a web site.
Use the resources on this page to find answers and remedies for your virus woes, but please consider buying or downloading antivirus software to protect yourself, your family, and your company from viruses, worms, scripts, and other forms of malicious code.

Shareware Antivirus Software
I do not list or recommend antivirus shareware for two reasons: (a) shareware may be supported through unsolicited advertising, I won't list what I haven't tested and I can't be sure (harsh!) and (b)there's no reason to try shareware when commercial home and personal use antivirus software is priced competitively, and I can recommend several "personal use only" antivirus products that I've tried and have proven useful.
