How to avoid email viruses and worms


Here are some simple rules you can follow to avoid being infected by viruses through email.

Doís

Use a professional and dedicated email service such as Runbox with strong virus filtering. Subscription services often provide higher levels of security and support.
Make sure that your Runbox virus filter is activated.
Use the Webmail interface at www.runbox.com to read your email, as it will never open an attachment by itself.
Donít download all your email to an email client unseen. Screen your email first, and delete suspicious-looking and unwanted messages before downloading the legitimate email to your local email client.
Make sure your computer has updated anti-virus software running on it. Automatic updates are essential for effective virus protection. Combined with server side scanning, you now have two layers of security.
Disable message preview in your email client, especially on Windows platforms. Otherwise, malicious programs attached to incoming messages may execute automatically and infect your computer.
Ignore or delete messages with attachments appearing to be sent from official Runbox email addresses. We practically never send email with attachments to our customers, so if you receive such an email it could be falsified.
Take caution when opening graphics and media attachments, as viruses can be disguised as such files.
Maintain several independent email accounts. If a virus infects your only business email address, youíll be in trouble. Also, keep backups of your most important email and files separately.

Doníts

Do not open an email attachment unless you were expecting it and know whom itís from.
Do not open any unsolicited executable files, documents, spreadsheets, etc.
Avoid downloading executables or documents from the internet, as these are often used to spread viruses.
Never open files with a double file extension, e.g. filename.txt.vbs. This is a typical sign of a virus program.
Do not send or forward any files that you havenít virus-checked first.
Viruses and spam
Virus-makers and spammers often cooperate in devious schemes to send as much spam as possible as efficiently as possible. They create viruses that infect vulnerable computers around the world and turn them into spam-generating ďrobotsď. The infected computers then send massive amounts of spam, unbeknownst to the computer owner.

Such virus-generated email is often forged to appear to be sent from legitimate addresses collected from address books on infected computers. The viruses also use such data, combined with lists of common (user)names, to send spam to huge numbers of recipients. Many of those messages will be returned as undeliverable, and arrive in innocent and unknowing email usersí Inboxes. If this happens to you, use the trainable spam filter to catch those messages.

TIPS to avoid email viruses

    Use common sense. If something looks suspicious or if you get an attachment from someone you donít know, donít open it.
    Purchase and install an anti-virus program. Make sure you update as needed. The first time you update, youíll have to manually update. Thereafter it should make automatic updates for you.
    Use your new anti-virus program to scan your attachments before you open them.
    If your e-mail automatically opens attachments, disable this feature.
    Schedule regular scans with your anti-virus software.

hai

nstall anti-virus software on all your desktops and servers, and ensure they are kept up to date. New viruses can spread extremely quickly, so have an updating infrastructure in place that can update all the computers in your company seamlessly, frequently, and at short notice.

Run email filtering software at your email gateway as well, in order to protect your business from the threats of email-borne viruses, spam and spyware. And donít forget to protect your laptop computers and desktop computers used by home workers. Viruses, worms and spyware can easily use these devices to enter your business.

Block file types that often carry viruses
These include EXE, COM, PIF, SCR, VBS, SHS,CHM, and BAT file types. It is unlikely that your organization will ever need to receive files of these types from the outside world.
