How viruses spoof the from-address in emails

You have effective anti-virus software, so your computer is clean,
You send an email to Fred,
Now your email address is in Fred's address book in his email software,
Fred does not have effective anti-virus software, and his computer has a virus,
The virus on Fred's computer scans his address book for all of the email addresses on it,
The virus sends email to every address on Fred's address book,
The virus emails do not say they are from Fred!, The virus pics another addresses from Fred's address book and puts it in the 'From field' in the outgoing email. The virus may combine the name from one address and the domain from another, creating a 'from address' that does not exist.
These emails are received by other computers, which detect the virus (because they have good anti virus software) and reject the email,
When the receiving computer rejects the viruses email it sends an 'Undeliverable' to the sender e.g. something like 'Subject: /Delivery Notification: Delivery has failed'.
But! the 'Undeliverable' note goes to the spoofed from address (not to Fred) e.g. the 'Undeliverable' note could be sent to you.
Often there is no trace of Fred's real address in the virus email or the 'Undeliverable' note, so you can not tell who's infected computer is sending these emails.
The solution: Make sure you have good anti-virus software and tell everyone you know to do the same.

Prevent Virus Attacks

You must run quality security software on your computers to protect your work and private data from viruses, spy ware, and other security threats. When it comes to security, there is no substitute for quality. See below our recommended quality solutions. If any of the following is difficult for you, get an IT Expert to do it for you. You must do the following or risk all of your work/data being compromised (think of it as locking your front door):
Get good anti virus software e.g. one of the below.Recommended anti virus software:- AVG - Our most recommended anti virus software.- Norton Anti virus- McAffee Anti Virus- Sophos Anti VirusBe sure to regularly update your 'virus definitions' e.g. once per week
Install a quality FirewallThere are many firewalls available, some good, some bad. Our recommendation is the FREE zone alarm. They provide a paid version with extra tools (of course), but we think the free firewall-only option is fine. Its getting harder on their site to see the free one (so look carefully!). At time of writing, go here, scroll down and click the free option. If the above link doesn't work, start looking from the Zone Alarm front page.
Install an anti-spy ware applicationThere are many available, some good, some bad. Our recommendation is the FREE: Spybot - Search & Destroy. Download here, and find Spybot info here.
Email Attachments: BEWARE OF ATTACHMENTS. Do not open email attachments you are not expecting. Viruses come with some very nasty messages to trick you into opening the attachment e.g. "Your email account has been canceled, see attachment for details". Even worse, the virus looks like it comes from an email address you recognize e.g. from admin@yourDomain.com (where 'your domain' is the domain name that you use). Virus attachments can have the following 'file extension': .exe, .pif. If you receive a .zip attachment and open it - make sure it doesn't contain a file with one of those extensions. Do not open attachments you haven't requested, even if they appear to be from people you know.

I'll take this off once you put into your first post zain.1. Start2. Run3. Type: command4. To move into a directory type: cd c:\*** (The stars stand for your folder)5. If you cannot access the folder because it has spaces for example Program Files or Kazaa Lite folder you have to do the following. instead of typing in the full folder name only take the first 6 letters then put a ~ and then 1 without spaces. Example: cd c:\progra~1\kazaal~16. Once your in the folder the non-deletable file it in type in dir - a list will come up with everything inside.7. Now to delete the file type in del ***.bmp, txt, jpg, avi, etc... And if the file name has spaces you would use the special 1st 6 letters followed by a ~ and a 1 rule. Example: if your file name was bad file.bmp you would type once in the specific folder thorugh command, del badfil~1.bmp and your file should be gone. Make sure to type in the correct extension.
