I can't imagine anyone being internet/email active and not having virus protection. The software is only around $30.00. As a part time systems administrator at the company I work for, I have cleaned up virus messes too many times because someone shut off their virus protection! Don't get protection soon, get it NOW! All you need is the wrong virus to get in and wipe out your hard drive and you'll wish you'd spent the money when you could have.
File backups are also a good thing...

Good advice, Mike! A regular backup routine is a must. Also a good idea to make a backup once a month and put it at another location or in a safe deposit box (in case of fire).

VBS.Pelic.Worm
Discovered on: October 01, 2002
Last Updated on: October 07, 2002 10:30:35 AM
VBS.Pelic.Worm spreads through mIRC and also the file-sharing network KaZaA. It tries to delete antivirus software on the infected computer.
Also Known As: IRC.Worm.Generic
Type: Worm
Infection Length: 7915 bytes
Systems Affected: Windows 95, Windows 98, Windows NT, Windows 2000, Windows XP, Windows Me
Systems Not Affected: Microsoft IIS, Macintosh, UNIX, Linux

Payload:
Large scale e-mailing: Spreads usingmIRC
Deletes files: Deletes AV files
Modifies files: Modifies autoexec.bat and HTML, HTT, HTM files
Distribution
Shared drives: Copies itself to the shared folder of KaZaA.
VBS.Pelic.Worm spreads using mIRC channels by adding a line to the Script.ini file.
If the worm is running, when you joining a chat channel, the script displays the message
hola , soy francisco , quieres tener todas las peliculas que quieras ver!
English translation: "Hello, I am Francisco. Do you want to have all of the films that you want to see?"
It then creates a file named C:\Windows\All_acces_videos.exe.vbs.
When the worm runs, it creates copies of itself as:
C:\Windows\autoexec.bat.vbs
C:\Program Files\KaZaA\My Shared Folder\Sex-free.exe.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Windows-xp-full-edition.exe.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Shakira-sex-anal.jpg.vbs
C:\Program Files\KaZaA\My Shared Folder\Mix-brazil.mp3.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Porto-seguro.mp3.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Asereje.mp3.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Quake 2.exe.vbs
C:\ARCHIV~1\KaZaA\My Shared Folder\Half-life_complete_version.zip.vbs
C:\Windows\Quake2.exe.vbs
C:\Windows\all_acces_videos.exe.vbs
C:\Windows\kazaa\all_acces_videos.exe.vbs
C:\Windows\kazaa\sex_all.exe.vbs
C:\Windows\kazaa\quake2_full_version.exe.vbs
NOTE: These paths are hard-coded.
The worm searches for major antivirus programs and attempts to delete files in the program's folder.
The worm modifies Autoexec.bat by adding the lines:
@Start C:\windows\Quake2.exe.vbs>nul
cls
It then searches drives C, D, and E for mIRC scripts to infect. If mIRC is installed on any of these drives, the script modifies Script.ini to send a copy of the worm to other users via mIRC.
It creates the registry key
HKEY_CURRENT_USER\software\Legion\sistem
and adds the value
infected
If this value is set, the worm overwrites .html, .htt, and .htm files with its code.
The worm also alters the KaZaA sharing registry key
HKEY_CURRENT_USER\Software\Kazaa\LocalContent\DisableSharing
which is set to
00000000
Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":
Turn off and remove unneeded services. By default, many operating systems install auxiliary services that are not critical, such as an FTP server, telnet, and a Web server. These services are avenues of attack. If they are removed, blended threats have less avenues of attack and you have fewer services to maintain through patch updates.
If a blended threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services.
Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
Configure your email server to block or remove email that contains file attachments that are commonly used to spread viruses, such as .vbs, .bat, .exe, .pif and .scr files.
Isolate infected computers quickly to prevent further compromising your organization. Perform a forensic analysis and restore the computers using trusted media.
Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.
NOTE: These instructions are for all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.
1. Update the virus definitions.
2. Run a full system scan, and delete all files that are detected as VBS.Pelic.Worm.
For details on how to do this, read the following instructions.
To update the virus definitions:
All virus definitions receive full quality assurance testing by Symantec Security Response before being posted to our servers. There are two ways to obtain the most recent virus definitions:
Run LiveUpdate, which is the easiest way to obtain virus definitions. These virus definitions are posted to the LiveUpdate servers one time each week (usually Wednesdays) unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, look at the Virus Definitions (LiveUpdate) line at the top of this write-up.
Download the definitions using the Intelligent Updater. Intelligent Updater virus definitions are posted on U.S. business days (Monday through Friday). They must be downloaded from the Symantec Security Response Web site and installed manually. To determine whether definitions for this threat are available by the Intelligent Updater, look at the Virus Definitions (Intelligent Updater) line at the top of this write-up.
Intelligent Updater virus definitions are available here. For detailed instructions on how to download and install the Intelligent Updater virus definitions from the Symantec Security Response Web site, click here.
To scan for and delete the infected files:
1. Start your Symantec antivirus program, and make sure that it is configured to scan all files.
Norton AntiVirus consumer products: Read the document How to configure Norton AntiVirus to scan all files.
Symantec enterprise antivirus products: Read the document How to verify a Symantec Corporate antivirus product is set to scan All Files.
2. Run a full system scan.
3. If any files are detected as infected with VBS.Pelic.Worm, click Delete.

Forgot to add, once you get that software installed, make sure you keep your virus definitions updated at least weekly. Norton, and I assume newer versions of Mcaffee, have an automatic updater that is nice. Software is no good if you don't keep it updated!
Personally, I like Ron's idea of keeping his accounting/client files on a separate computer with no network/internet access. Too many of us don't keep many hard copy records anymore.

www.xdrive.com and a few others of this ilk sell cyber space which is handy if you use your computer to work and play.
for general surfing and getting people to mail you or send you stuff...evreyone should have a hotmail address...as it is free.....they upgrade there virus checking every day, as there are virus's now that you dont have to open to get infected.
oneness,
if you are a sys\admin you should go into the main server software and after you have setup all the machines the way you want to....disable all the access to programs that you dont want touching and control panel via the registry.......there must be software out there to do it by now aswell.
cheers paul.

Paul:
The system I am "in charge of" (meaning they call me when stuff breaks) is a 10 system peer to peer Win98 network. There is no server software, nor is there really a server. One day I will maybe talk the owner into going to a server system with real network software, but until then, there's not a lot I can do to control the users, other than try to educate.
