To protect your PC you need to take preventative steps to ensure
that Spyware/Adware doesn't come back. Install an anti-spyware
prevention program. Be choosy about the free programs you download.
Keep your operating system up to date. Understand your browser's
security settings. Block"add servers" with your HOST
file.
Install an anti-spyware prevention program. SpywareBlaster* and SpywareGuard* are
excellent, free programs. You may want to install and use both,
as they protect your computer in different ways. SpywareBlaster* "inoculates" your
Internet Explorer browser against the installation of unwanted
spyware and adware from the internet. SpywareGuard* actively
monitors your PC and prevents spyware infestations.
Be careful downloading free programs. The
best defense against spyware and other unwanted software is
not to download it in the first place. Only download programs
from Web sites you trust. Read all security warnings, license
agreements, and privacy statements associated with any software
you download. Never click "agree" or "OK" to
close a pop-up window. Always use the "x" in
the corner. Tip: Before
downloading and installing a free application, look it up on
one of several online spyware databases. Spychecker* and Cexx.org* are
two such services.
Keep your operating system up to date. Download
and install the latest updates, "patches", for
your operating system and Internet software, including your
web browser and your e-mail client. Even with updated anti-virus
software your computer is vulnerable if it has not been patched.

Block Ads with the HOST File. You can
use a HOSTS file to block ads, banners, cookies, web bugs,
and even most hijackers. This is accomplished by blocking the
Add Server that supplies the adds.
The HOST file contains a listing of
Internet addresses. When you access the Internet with your
browser, it normally first checks a local "HOSTS" file
to see if the url you have entered (such as "www.sc.rr.com")
is mapped to some IP address. If so, this IP address is accessed
directly. If not, then your ISP's computer is accessed, and
the IP address of the URL is located, and then the browser
goes to that IP address.
Your own machine has its own IP address, 127.0.0.1.
If you create a local HOSTS file,
and map a given server URL to this IP address, then when you
provide the URL to your browser, your browser will just go to
your own machine. Result: no info is transferred to your machine
from that "adserver", nothing is transferred from your
machine to that "adserver", your surfing activity is
not tracked by that "adserver," and your visits to
the page you are trying to visit are much faster!

Improper use of this information may prevent you from getting

1. Determine the location
of your HOST file:
Windows XP = C:\WINDOWS\SYSTEM32\DRIVERS\ETC
Windows 2K = C:\WINNT\SYSTEM32\DRIVERS\ETC
Windows 98, Me = C :windows\hosts
Macintosh: Mac System Folder or Preferences
folder. (eg., Macintosh HD:System Folder:Preferences:Hosts)
2. Backup your HOST file - It's
a good idea to save your original HOST file in a safe location
on your computer in case you encounter problems.
3. Download the HOST file - Download
the HOST file* from PestPatrol* and
save it on your computer. Copy the HOST file to:
Windows XP = C:\WINDOWS\SYSTEM32\DRIVERS\ETC
Windows 2K = C:\WINNT\SYSTEM32\DRIVERS\ETC
Windows 98, Me = C :windows\hosts
Macintosh: Mac System Folder or Preferences
folder. (eg., Macintosh HD:System Folder:Preferences:Hosts
4. Locking the HOSTS
File - After updating your host file, you might want
to make it "read only". Some malware programs will
attempt to add their own entries or overwrite your HOSTS file.
Remember to remove the read only status before updating the
file or the update will not be accepted. To make your HOST
file "read only":
1. Right click the HOST file
2. Select Properties
3. Under the General tab check Read Only
Please note:
In some cases a large HOST file tends to slow down the computer.
This usually only happens in W2, but may occur in XP. Here
is what to do if this is an issue for you: Open My Computer,
Control Panel, Administrative Tools, Services - Scroll down
to "DNS Client", Right-click and select: Properties
- Click the drop-down arrow for "Startup type" -
Select: Manual, click Apply\Ok and restart.
