- Don't use Outlook and Outlook Express. This may not be realistic advice in the real world, but you
- should at least use Love Bug as a
reason to re-evaluate what your shop standards are for e-mail clients.
Viruses often target Outlook and/or Outlook Express; using other
clients minimizes your exposure. Beware, though, that avoiding Outlook
isn't unconditional protection. Love Bug required Outlook to replicate
itself but was able to damage PCs in the absence of Outlook.
- Make all users aware of the dangers of unsolicited attachments. E-
mail viruses rely on users opening infected attachments. All e-mail
users must understand the potential consequences of opening attachments
from bad guys.
As a further reminder of how dangerous attachments can be, consider creating an incoming mail rule in Outlook that directs all e-mails with attachments to an attachments-specific folder. I now use an Outlook rule that directs mail with attachments to a folder called BeCareful. Putting mail with attachments in this folder doesn't make it impossible to launch them, but it does help provide me with a constant reminder that e-mails with attachments should be treated with special care.
- Use antivirus software and keep it current. Antivirus software
isn't foolproof: Early in Love Bug's life antivirus software offered
no protection against the virus because it hadn't yet been identified
as a virus. Despite a potential limitation on late-breaking viruses,
good antivirus protection is mandatory! Get an enterprise antivirus
subscription and keep it current. Also, virtually all antivirus
vendors offer e-mail services to update you with late-breaking virus
news. (See URLs below.)
- Be aware of the need for secondary virus fixes. Even after McAfee's
antivirus software had removed infected files from my PC, I still had
residual entries in my registry. To fix such spurious side effects,
you'll often need to run adjunct software to fully rehabilitate
infected PCs. Norton has published a free secondary fix called
FIXLOVE.EXE on its Web site that worked for me. (See URL below.)
- Disable the Windows Scripting Host. The Windows Scripting Host (WSH)
is Windows' solution for a robust batch processor -- it is primarily a
replacement for DOS BAT files. WSH not only provides a rich scripting
Unless you have a specific need for WSH (and you probably don't), disable this way:
- Open the Control Panel.
- Open the Add/Remove Programs applet.
- Click the Windows Set-up tab.
- Double-click Accessories.
- Deselect Windows Scripting Host shown in the Accessories list. If it isn't already selected or present, it currently isn't installed on your system.
- Click OK twice.
