Windows 95 and windows 95b (OSR2)
are now essentially obsolete. They are barely supported by Microsoft
and what little support still exists is expected to be discontinued
in the near future. Neither version of Windows 95 is sufficiently
secure for use on the internet, even with all the latest patches
and security updates applied.
We strongly recommend anyone using
Windows 95 to upgrade to Windows 2000 or Windows XP as soon as
possible. If you cannot do so, you must ensure you are running
Winsock 2.0 or your system will be vulnerable to many simple denial-of-service
attacks. You will also need to disable File & Printer sharing
and remove the Netbios protocol from your connection properties
or malicious users will easily be able to read and write data
to your disk.
The version of Internet Explorer
which shipped with Windows 95 is also obsolete and subject to
some severe security issues, you should upgrade to at least Internet
Explorer 5.5 or better yet use an alternative browser such as
Netscape Navigator.
Outlook Express is not a secure
mail and news client in any incarnation (including the latest
version) and should really be avoided. There are many alternative
news & mail clients, many of which are available for free
download.
A personal firewall can help reduce
the likelyhood of a compromise however Windows 95 is not a good
platform on which to run firewall software. Ideally if you must
use a windows 95 machine to access the internet it should be sited
behind a NAT router or a secure firewall/gateway.
