Tip of the moment: Ignore 'Your Paypal Account Could Be Suspended' messages


Don't run telnet (or open FTP) on any servers, routers or other infrastructure!

If you run Windows, do yourself a BIG favour and use PopTray, NOW!!!!! This allows you to keep your e-mail client closed and will also block unwanted spam (by installing the example Rules.ini file given here):

Frequently Asked Questions:

Q. Why is this page a bit disorganized?

A. Viruses, spam and Security have become so inter-connected that to consider each in isolation is almost impossible. Writing a page which covers this subject is a vast job!

Q. Does that mean I should install everything on this page?

A. To be absolutely sure, yes. Of course, don’t install two anti-virus programs or two firewalls.

Q. Should I be constantly on the alert for the latest threats?

A. Within reason, yes. Without spending all your time doing it.

Q. What prevention measures are in place on your server?

A. The first thing an incoming email hits is an absolute brickwall which refuses email from some addresses and domains. This blocks very well known spammers. On a daily basis, this list is updated on the basis of real received spam. Next, the email passes through SpamAssassin. This is the highest rated server spam blocker in the industry. Finally, our latest feature, special files in the web site areas prevent spam-bots from harvesting email addresses automatically from your webpage. Webmasters must not remove these files, or this protection will be lost.

Q. How often should I update my programs?

A. Whenever and as soon as you can

Q. Why do I get so much spam?

A. With all of these measures in place, you should see a reduction in spam, especially with our new spam-bot blocker. However, spam is growing at at least 10% per month, so our latest measures, whatever they are, may seem to do no good.

Why so much spam, or why does some of your email “go missing” went sent to others?

The longer your email address is in service, the more you will receive. Period.

How to attract spam:

Visit “bargain” sites and sign up for email alerts.

Simply register with many web sites.

Allow pop-ups & cookies (at the very least it’ll tempt you to “break the rules”).

Leave your email address wide open on your website for spam-bots to collect.

Catch a virus.

Have somebody you know catch a virus and flood the internet with your email address from their address book.

 

How to “lose” email sent to others: (trigger spam filters)

Use an empty subject line.

Use an empty From: line.

Use subjects such as “Check this out”, “Re:”

Attach .exe, .pif, .scr and other file types.

Use a bulk email service (they break nearly all of these “rules”)

Use lots of HTML tags.

Use phrases such as “click here” or “to unsubscribe”

 

What’s an “acceptable” amount of spam? Anybody who “plays by the rules” will still receive spam, probably at the rate of 2-3 per day i.e. if you log on on Monday morning you should almost expect there to be 8-10 spam emails awaiting you after a weekend off.

 

Q. Aren’t you a bit anti-Microsoft & other big companies?

A. Well, yes, but for good reasons. Ours and our customers findings have been that many of the open-source or free versions of anti-virus, firewall, email clients & browsers are superior in speed and performance than “mainstream” applications. Example: a machine infected with 18 viruses failed to have them detected by up-to-date versions of McAfee and Norton. AVG detected them and removed them on the first pass.

Frankly, we all know the faux-pas’ made in security by many of these companies. Not that open-source is perfect; but the time from finding a problem to fixing it is often much less than in the big corporations.

 

Now, let’s get on with fixing things!

Test your Security
ShieldsUp
How can I see if my machine is sending out spam behind my back? You can look at Internet activity on your PC. A simple visual proof is to install NetMeter. If you see attempts to send out data every few seconds then you might have a problem. To test it further, you can download the rather complex Wireshark which will give all the details of what is going on. When you do this, makes sure that your browser, email client and any other programs that talk to the internet are not running.
