How prevalent is Spam? According to Scott McAdams, OMA Public Affairs and Communications Department (www.oma.org):

“Studies show unsolicited or “junk” e-mail, known as spam, accounts for roughly half of all e-mail messages received. Although once regarded as little more than a nuisance, the prevalence of spam has increased to the point where many users have begun to express a general lack of confidence in the effectiveness of e-mail transmissions, and increased concern over the spread of computer viruses via unsolicited messages.”

In 2003, President Bush signed the “Can Spam” bill, in December of 2003 which is the first national standards around bulk unsolicited commercial e-mail. The bill, approved by the Senate by a vote of 97 to 0, prohibits senders of unsolicited commercial e-mail from using false return addresses to disguise their identity (spoofing) and the use of dictionaries to generate such mailers. In addition, it prohibits the use of misleading subject lines and requires that emails include and opt-out mechanism. The legislation also prohibits senders from harvesting addresses off Web sites. Violations constitute a misdemeanor crime subject to up to one year in jail.

One major point that needs to be discussed about this: spam is now coming from other countries in ever-greater numbers. These emails are harder to fight, because they come from outside our country’s laws and regulations. Because the Internet opens borders and thinks globally, these laws are fine and good, but do not stop the problem.

So what do you do about this? Her are the top 5 Rules to do to protect from spam.

1. Do what you can to avoid having your email address out on the net. There are products called “spam spiders” that search the Internet for email addresses to send email to. If you are interested, do a search on “spam spider” and you will be amazed at what you get back. Interestingly, there is a site, WebPoison.org, which is an open source project geared to fight Internet “spambots” and “spam spiders”, by giving them bogus HTML web pages, which contain bogus email addresses

A couple suggestions for you: a) use form emails, which can hide addresses or also b) use addresses like sales@company.com instead of your full address to help battle the problem. c) There are also programs that encode your email, like jsGuard, which encodes your email address on web pages so that while spam spiders find it difficult or impossible to read your email address.

2. Get spam blocking software. There are many programs out there for this. (go to www.cloudmark.com or www.mailwasher.net for example). You may also buy a professional version. Whatever you do, get the software. It will save you time. The software is not foolproof, but they really do help. You usually have to do some manual set up to block certain types of email.

3. Use the multiple email address approach. There are a lot of free email addresses to be had. If you must subscribe to newsletters, then have a “back-up” email address. It would be like giving your sell phone number to your best friends and the business number to everyone else.

4. Attachments from people you don’t know are BAD, BAD, BAD. A common problem with spam is that they have attachments and attachments can have viruses. Corporations often have filters that don’t let such things pass to you. Personal email is far more “open country” for spamers. General rule of thumb: if you do not know who is sending you something, DO NOT OPEN THE ATTACHMENT. Secondly, look for services that offer filtering. Firewall vendors offer this type of service as well.

5. Email services now have “bulk-mail” baskets. If what you use currently does not support this, think about moving to a new vender. The concept is simple. If you know someone, they can send you emails. If you don’t know them, put them in the bulk email pile and then “choose” to allow them into your circle. Spam Blocking software has this concept as well, but having extra layers seems critical these days, so it is worth looking into.

A coworker of mine had mentioned logmein.com before and today I decided to try it our. If you have ever used RDP or WinVNC to remote onto a computer then you will understand the idea behind logmein.com.

Logmein works as a remote control program by signing up for an account and then installing an activeX control on a target machine (an end user can do this for you) and then you have this new machine listed on the logmein.com website. The site then uses port 80 (regular internet port) to create a VNC like connection to the remote machine and you then have shared desktop control with the other person. This is a really easy way to setup the application as you do not have to know the IP or any other info to setup your connection to the other computer.

Logmein also offers file sharing and a simple ftp type setting but this is only good for the first 30 days while you are using the Pro version of logmein after 30 days you revert to the free version and this only includes the remote desktop.

If you opt for the pro version of logmein it is $12.95 per month which is a little steep and the price drops to 9.95 per month per PC for 2-10 PCs. If all you want is remote access to a machine then the free account is all that you need. Also using the free version you seem to have access to as many remote machines as you want to set the application up on which is probably good enough for most people running a computer support business.

Microsoft today announced the first Release Candidate of the Windows Home Server. This is going to be the hub of peoples home networks.

Right now, for most people the center of the home network is the wireless router in the basement or living room and all of the computers are basically their own entities. I have tried to go a bit beyond that by sharing out the favorites between machines as well as my wifes scrapbooking folder but otherwise we still have the same as most people. Three computers are in my house and each of the computers has it’s own shared folders, it’s own data and it’s own applications. This is disjointed to say the least.

Windows Home Server is going to centralize all of the file serving with central storage of all files and backing up of all machines on the network. There will also be the ability to share pictures over the internet.

All of these features are doable now with a Windows 2003 server but this server system is streamlined and is the kind of thing that any family should be able to use and configure for the safety and convenience that most people do not have the knowledge of or the interest to learn.

Microsoft has a public beta available now so that you can try the windows Home Server out.

Top 15 Ways to Extend Your Laptop’s Battery Life

I have recently switched to a laptop from a desktop and besides the ability to be untethered from a desk it has taken a bit of time for me to start using the laptop just on battery power…which I know do. One thing to make sure that you have is some kind of software to be able to see how much life is left in the battery. I use Battery Meter Plus which is a free application for Windows that shows a little bar on the side of your screen and as the battery starts to die it will get stronger on the screen and show you how much time you have left.

In some cases, spies and covert operations are found in war grounds or politically tense regions. Now however, you can find spies and covert operations running undetected within your personal computer system as you use your computer and the Internet.

Have you noticed a suspicious slow down of your computer’s processing without any particular reason? Are you bombarded by unsolicited pop up ads that indiscriminately appear whether you are running a program or not? These symptoms may continue to happen despite checking your system and running your recently updated anti virus program to run diagnostics on your computer.

Unless you run the correct program, you will not be able to detect the real problem in your system: spyware and adware.

Adware are unsolicited programs that usually come bundled with freeware or shareware. Yes, sometimes things that seem to be good to be true usually come with unwanted invisible strings attached. Companies usually pay freeware or shareware creators to be able to capitalize and prey on unsuspecting individuals who download these programs. Adware cause unsolicited pop up advertisements in your computer and in severe cases, adware causes pop up advertisements to pop up soon as you boot your system.

Spyware on the other hand is more covert and usually undetected in your system until you run an anti spyware program. Spyware is used exactly to spy on you. In relatively mild cases, spyware is used to track your Internet browsing habits so that the spyware can report your preferences to build a marketing profile. This means that as you go about your Internet business, you are under surveillance and your basic right to privacy is impinged upon.

In severe cases though, certain spyware better labeled as malware, are used for criminal purposes and can steal keywords and other sensitive information based on your computer and Internet usage.

For instance, malware can take note of your keystrokes or take note of your credit card number and other vital information that can be used to steal your identity and generally put your security at risk.It is said that 9 out 10 computers are infected with spyware and to make sure that you are not part of statistical majority, you need run an adware and spyware cleaner to detect unwanted security and privacy breach within your system.

There are a lot of reliable adware and spyware cleaners in available to remove these unwanted programs in your computer. You must note however that some adware and spyware are intricately bundled within their parent programs that cleaning them out from your computer will inadvertently disable the legitimate programs they infect. This consequence is a necessary evil to clean your computer of unwanted adware and spyware. You should choose an adware and spyware cleaner that can also work proactively by preventing future accidental installation of these nuisances.

Adware and spyware cleaners work like your anti virus programs except that these particular cleaners target adware and spyware.Considering the trouble adware and spyware creators take to ensure that extracting installed adware and spyware from your computer system will be difficult, the adage about an ounce of prevention being worth more than a pound of cure applies in this situation. Be sure to install a reliable and secure adware and spyware cleaner in your system to remove existing security and privacy risks as well as preventing future hassle.
