Exploits are Everywhere, Even in Common File Types

Posted by Mike

As security advances so does the opposition. Many malicious software makers are starting to notice that the average PC user is becoming smarter when it comes to avoiding emails that could be potentially harmful.

Recently these malicious programmers have started to take a different path. They have begun to create different types of threats. One type that you may have already seen is where the program will inform the user needs to download security software. Three other major programs which are known as Win32/FakeXPA, Win32/FakeSecSen, and Win32/Renos have been found on millions of computers.

Attacks have also been taking place in common files such as .PDF and .DOC. Even Adobe Reader 9 and Acrobat 8 have had several exploits in them. While there are updates out for these programs, many users don’t update their software. For example over 90 percent of attacks in Microsoft Office have been from an exploit that could be fixed with a simple update. Surprisingly this update is over 2 years old!

While many PC users look for updates through Microsoft they rarely look to update other programs. There are a lot of PC users that believe that the Microsoft updates will solve everything. While Microsoft does run the PC business due to most users using Windows, they can’t watch over every company’s individual software issues such as the issue with Adobe.

It’s surprising how many people have issues with malicious software but do nothing to fix it. There are updates for programs coming out all the time to fix these holes and help prevent attacks however many users don’t seem to check for updates as they should. Microsoft alone last year released 78 updates that fixed 155 issues.

Therefore if you are having continuous problems with attacks you should ensure that everything on your computer is up to date. While you may update Windows constantly it’s not enough to stop someone from attacking your computer.

Original Sin

Posted by Ruel

Catholics have this belief that every child that is brought out in the world has original sin. This sin comes from mankind’s biblical ancestors, Adam and Eve. In order to get rid of original sin, the child has to be baptized. After being Christened, the child begins life without any burden of sin.

That sinless existence also comes a few times in a PC’s life. The system doesn’t bear the weight of any needless software during the time that it’s taken out of the box. Of course, a computer is practically helpless or useless without any application installed in it. The first burden that it has to carry, then, is the operating system.

First Sin?

Many consider Windows as the first sin or burden of a computer. Everything seems to be perfectly fast and smooth when a new PC conducts that first run or check in DOS or Linux. However, such pristine condition or impeccable performance won’t last long. As no PC could ever survive or be useful without embracing Apple or Microsoft’s religion, the commission of original sin is consequently inevitable.

Putting it to the Test

Of course, operating systems are made to make things easier for the user. Hence, it’s quite wrong to look at it as if it’s Pandora’s box. Of course, your system will definitely slow down once it begins to run on Windows or OS X. That’s just normal considering that DOS or Linux practically needs just a fraction of processing power in order for it to function. In contrast, Windows or OS X will definitely put processors to the test, especially if it’s a single core model.

Still Pure

Despite taking up a few gigabytes of hard drive real estate, as well as keeping task manager busy, your PC should still be able to run smoothly after the installation of XP, Vista, or OS X. I’ve installed XP on a Pentium M notebook with just 256 of RAM and it ran without a glitch. Navigating through the commands or windows was seamless. The ease by which I was able to go through things or tasks made me wonder for a short while if the specs of my notebook were mistakenly labeled.

Problem in Disguise?

Slow PC performance starts when you install the other applications. You’ll definitely feel the drag after you’ve installed an antivirus. It’s already a given that the presence of a security software in your system will slow it down. That’s a consequence that every PC user will face regardless of the processor that he has.

Some users try to solve the problem by getting rid of their antivirus altogether and just rely on their cautious nature to ferret out malware attacks. Of course, this is a reckless move. Antivirus or other system utilities will slow your PC down. However, the greatest drag or burden that keeps PCs from running at optimum speed comes from malicious applications and not from legitimate ones. You may not notice this immediately, but you’ll definitely be noticing your nails grow while waiting for your programs to load if you’ll let your system roam around cyberspace without any armor on it.

Necessary

Do not court disaster by dispensing with system utilities that you think would just waste hard drive space or slow down your system. Antivirus programs or registry cleaners may take up some space and may sometimes demand a good deal of processing power every time they’re scanning your PC for malicious instructions. The small inconveniences that you’ll experience from scans and clean ups are nothing compared to the major hard drive sweep that you’ll be doing when unwanted software starts squatting on your main disk.

Picture-Perfect Alternatives

Posted by Ruel

With the advent of the digital camera, one could not certainly help but advance the opinion that the days of photo-developing shops or labs are already numbered. Ever since I bought my Canon Powershot 430, I gradually ceased to be a customer of the photo studio near our workplace.

It doesn’t take much to learn how to edit a photo on a computer. Nowadays, even a kid could make his freckles or pimples disappear with just a few clicks of the mouse button. I’m quite ashamed to admit that I’m one of those who conduct retouches on his photos before publishing or printing them.

The program that I use to make my photos clearer (and deceivingly beautiful) is Adobe Photoshop. This application packs all the features or functions that one needs in editing or processing photos. Of course, the snapshots should come from digital cameras. However, images coming from traditional cameras could also be modified by Photoshop. All you need to do is scan the photo and save it in JPEG or other image file format.

Needless to say, Photoshop is a powerhouse when it comes to editing pictures. However, if your image-editing need is usually just confined to resizing photos or conducting slight modifications, then you don’t need the Adobe program. There are plenty of photo-editing software on the Internet that costs less. Some are even given for free. Try these programs and see if they suit your needs. However, be careful when downloading them. There are times when these programs serve as cocoons for malicious software. Check them out first so that you’ll be sure that they won’t mess up your system’s registry or trash the other files in your hard drive.
