Question/Problem - What is email spoofing? Can I prevent it?
Answer/Solution - If you're receiving bounced (returned) emails that you have never sent
that have your own domains as the return address, and aliases that never existed, then almost always,
this is a case of header forgery, aka "Spoofing".
This is how it is done.
1. Spammer finds an email address or a valid domain. (Spammers spend their days looking for these.)
2. Spammer sends off a large email campaign using this domain, and various email tools that prohibit easy tracing of the origin. These tools cloak, scramble or remove the header entirely, removing them from initial blame, because most people just assume the mail actually came from the address it was "sent" from.
3. Innocent domain owner gets mail-flooded with bounce messages from the email addresses that weren't valid, or have blocking capabilities.
4. Spammer gets shut down by his/her ISP inside of a week, due to excessive bandwidth, complaints from people who figured out who actually owned the email, etc.
5. Spammer moves onto the next domain.
As you can see, this is incredibly hard to trace, and unfortunately, the general suggestion to get around this is to ignore the problem. You can create clearly defined/unique aliases, and use only those aliases. Then, set the catch-all to trash anything else. This narrows the possibility of your email box being flooded by returns, while the spammer is finished using that domain.
This is possibly the most frustrating abuse issue to deal with, simply because it cannot be stopped.
Spoofing is similar to hand-writing many letters, and signing someone else's name to it.
You can imagine a situation like that would be almost impossible to trace.

» Upgrading Your Memory to Improve Performance:
As programs get more complex, you’ll discover that your trusty PC may not be working as
quickly or efficiently as it used to. While your impulse might be to purchase a new,
more powerful computer, you can dramatically improve performance simply by upgrading your memory.
For far less than what you’d pay for a new computer, a memory upgrade will often have your PC
working faster and more efficiently than ever before.

» The Truth About RAM - Why it Pays to Go for 2 Gigs!:
Beefing up your PC’s memory is an inexpensive and surprisingly simple way to give yourself a huge boost in performance. Besides, today’s complex software and graphics-intensive games chew up your memory almost as fast as you can add it on. Therefore, it’s best to prepare for the immediate future by loading on as much memory as you can.
To give you an example how things are changing in the memory game, Microsoft advises that you need at least 128 MB of memory to run Windows XP, but with just that amount you will barely be able to run your computer, as it will be SO SLOW. Just remember the more the merrier, with 512MB minimum and 1Gig even better, your computer will run much smoother. With Vista, it is 2 Gig or more. Now with Windows 7, I would not recomend anything less than 2 Gig, although it will run with just 1. Back in the “old days” (circa 2000), the Redmond, Washington-based giant required only 64MB to run Windows 2000. So, you can see that memory requirements change rather quickly.
Many industry experts today recommend that you
upgrade to at least2 gigabyte (2GB) so you can be ready for the challenges
ahead of you. With a gigabyte or more of memory your PC will be able to run
multiple programs simultaneously and give you excellent speed.

» Five Minutes and a Small Investment Make a Huge Difference in Performance:
Two of the great things about upgrading your PC memory are the fact that it’s cheap (especially when you consider dramatically a significant memory upgrade will improve your performance), and it only
takes about five minutes to drop in another memory card. And when you’re done you will be
able to keep more programs running, ramp up your speed on memory-eating graphics programs
and play games like never before. Plus, your PC will handle like a precision machine.

» Spyware, Trojans and Browser Hijackers:
They are now a greater threat than viruses. They are harder to get rid of, affecting the performance and operation of computers more. They are software that is installed, running in background--without your knowledge. With two or more of these on one machine, it can be impossible to get any work done.
How much of an impact can spyware's, trojans and hijackers have on system performance?
Infected systems can slow to a crawl or stop functioning completely.
This increases operating costs across large networks by diverting time and attention
to dealing with this scourge. Spyware's and hijackers are expensive, stealing time,
energy and costing money for workers and home users alike.

» What is Spyware & Why should You Care?
Spyware is software that may be installed without
your knowledge when you download software programs from the Web or click
on email or IM attachments. It’s often associated with applications
related to file sharing, adult content and blog creation. Spyware monitors
your web browsing habits, delivers unsolicited pop-up ads, directs you to
advertising websites, and steals personal information to send to cybercriminals.
Your
PC could be further compromised by malware and bots, and your identity and
personal information could be at risk.
How to Protect Yourself;
Keep your PC current with the latest software updates and patches.
Apply
the latest security updates and patches to your software programs and operating
systems and enable automatic updates where possible. Since cybercriminals typically
take advantage of flaws in the software to plant malware on your PC, keeping
your software current will minimize your exposure to vulnerabilities.
Protect
your PC with security software.
Install an Internet security suite that includes spam filtering and blocking
as well as anti-malware and anti-spyware capabilities. Keep security software
up-to-date.
Scan your PC to see whether you have been infected.
Not all security suites
are built alike or recomended by us. Some will slow your computer down QUITE
a bit. Visit us to have quality software installed.
Protect yourself and your PC
Beware of unexpected or strange-looking emails and instant messages (IMs)
regardless of sender. Never open attachments or click on links in these
emails and IMs. If you trust the sender, scan the attachments before opening.
Beware
of web pages requiring software installation. Scan programs before executing.
Always read the end user license agreement and cancel if you notice other
programs being downloaded in conjunction with the desired program
Malware is a category of malicious software programs that includes
viruses, worms and Trojans. Malware spreads via email, the Web, and devices
like USB drives.
Different malware file components are often used together
to create blended – and effective – Web threats.
Viruses have the unique ability to replicate, and like biological viruses, can
spread quickly. Viruses typically damage your PC by reformatting your hard drive
or corrupting files.
Worms spread copies of themselves via email and instant message attachments,
and harm networks by consuming bandwidth.
Trojans perform malicious actions but have no replication abilities. Like the
original Trojan horse, these programs may arrive as a seemingly harmless file
or application but actually have malicious intent within their code.
Malware can compromise your PC security and put your personal identity and information at risk.

» Simple Guide to Burning CDs:
There are two types of recordable CD Media CD-R (CD-Recordable) and CD-RW (CD-Rewritable. While prerecorded CDs are pressed from a mold, recordable compact discs are actually burned with a laser, which is why the process of recording to CDs is known as burning. CD-R disks can only be recorded once. Once you create a CD using a CD-R disc you cannot add, delete or modify. CD-RW's can be erased and rewritten to, but you cannot add information without erasing the contents first.
The Basics of Burning
Everyone who buys a notebook wants to know how long its battery will last. The brief answer – it's highly variable depending on how your use your laptop. Batteries for laptops come in three main types: nickel cadmium (NiCad), nickel metal hydride (NiMH), and lithium ion. You can recharge each of these batteries with an AC adaptor. In most cases, it will give you between one and two hours of computer use, depending on a number of factors.
Following are five tips to help you get the longest battery life possible
