Is it too late to buy Antivirus software if I've already got a virus?      
No! Most commercial antivirus products are distributed on CDs that include an executable version of the program. This allows you to boot your infected PC then run a copy of the program from the CDROM, which, as read-only media, can't become infected.
 
Is it wise to run more than one Antivirus program? Or Is one enough?      
The truly paranoid will always point to test results that show all antivirus programs miss infections during controlled tests and claim this means the defense-in-depth approach of using multiple virus scanners is required.
 
How regularly are updates released?      
Responsible vendors release updates constantly in order to counter new virus threats, and offer free tools for cleaning PCs infected with viruses that disable their antivirus products. Check out the information on their Web sites to see when their virus definitions are updated, and what selection of viruses are included. This should provide a general idea of who is on the ball when it comes to protecting against new viruses.
 
Can it integrate closely with my e-mail program?      
Without tight integration between your mail program and the antivirus program your PC is an easy mark for all those nasty worms. Just remember to update the antivirus program before downloading your mail or it won't stand a chance of stopping them all.
 
Does it have a right-click shell extension to scan files?      
A shell extension is a small system utility which gives users the ability to manipulate the settings of the PC through the operating system.
 
Product Activation. What is it? And how does it affect me?      
Product Activation is a process where a user or application contacts the manufacturer (usually via the Internet, but it can be by phone or fax). It lets the software vendor know some information about the application running and to provide a response that may trigger a change in the application. In the case of antivirus programs this is important as the software activation will signal the beginning of the time cycle for free updates.

Friday Rant - When antivirus software goes bad      
I've long held the belief that antivirus software can be almost as bad as the malware it's trying to protect you from. In fact, I believe that it's a lot worse.
 
Desktop Security Suites for Small Businesses      
Desktop security suites were developed to help keep the computers up and working, to keep company information from going out to the Internet where it can be improperly used for marketing, spam, or identity theft, and to protect the company from liability resulting from sending customer data inappropriately, or having internal systems used to attack other businesses.
 
Proof that Antivirus software makes your PC crawl      
A few months ago I declared: "It's time to toss out your (desktop) antivirus software!" As far as I was concerned, running desktop antivirus software was a liability in and of itself because "Running antivirus on a personal computer is like having the bomb squad inspect a suspicious package inside the house right next to you." The effectiveness of antivirus software is also questionable since it won't work at all for zero-day exploits that haven't been updated yet. Well now there seems to be another good reason to toss out that antivirus software.
