3 Questions: Beware the attack of spyware      
With Roger Thompson, vice president of development,Pest Patrol. As if viruses, zombies, Trojans, and other assorted malicious software weren't enough, businesses of all sizes need to worry about spyware. This is a big category, ranging from legal software aimed at tracking the sites a user visits to illegal programs that can capture passwords, screen names, and keystrokes.
 
Worms do battle while users miss the point      
The rapid spread and equally rapid reengineering of some recent worms may be explained in large part by a raging war of words among the creators of the Bagle, MyDoom, and NetSky worms. At the end of February and beginning of March, there was a brief period when new versions of these worms were appearing every few hours.
 
Antivirus software alone is not enough protection      
When the Blaster, MS/SQL, and Sobig worms made their appearance on the scene in 2003, one thing became clear: none of the worms was initially stopped with antivirus software.
 
Why there is no global antivirus software conspiracy      
Since the first computer viruses appeared in the DOS era, there's been an ongoing digital arms race between the authors of malicious code and the companies that write antivirus software. Many people believe there's a global conspiracy going on between these two factions to benefit both groups. And for some, increasing virus and worm outbreaks, such as MSBlast, Nachi, and SoBig.F, only strengthen this belief.
 
Advanced viruses may elude detection      
Many IT pros feel helpless in the battle against the constant barrage of worms and viruses. When using antivirus software, the general rule is to update automatically or download the latest virus definitions at regular intervals. But the problem with antivirus software is that it only offers protection for known viruses; therefore, the software is only effective when it can detect specific patterns in viruses and worms. But someday this may not be possible.
 
Get more from your antivirus software      
You're probably running some type of antivirus software on every computer in your network--as you should. When you bought the package, did your vendor claim that its software would stop the latest viruses in the wild? In that case, your virus liability should be zero if you've properly configured the vendor's software on your servers and workstations, right? Of course, you know that's far from the truth. What your vendor meant was, "we stop all known viruses."
 
Don't trust antivirus vendors to do all the work      
At the recent Virus Bulletin conference in Orlando, FL, several representatives of major antivirus companies, as well as the organizers themselves, had similar messages embedded into their presentations. The messages boiled down to this: "Trust us; we're the experts."
 
How antivirus software works      
Antivirus software detects known viruses by consulting a database containing virus signatures. When the antivirus software finds a virus contained in its database, it disinfects the infected files. What happens, however, if you get a virus that isn't in the database?
 
Symantec System Center manages all your antivirus software      
If your antivirus software has outdated signature files, then it's completely worthless because new viruses will pass right by it. When you have a network with dozens or hundreds of workstations, keeping up with all of the virus signature files across your network can be a full-time job. Symantec has released the Symantec System Center (SSC) to help deal with this management nightmare.
 
Antivirus solutions from PC to enterprise      
When it comes to security investments, many IT pros relegate antivirus software to the bottom of the security list. It seems that firewalls, proxy servers, tape backups, and RAID configurations come first and foremost in data protection.
