Adobe Reader Flaw Could Compromise Your Computer
There is a flaw in Adobe Reader and Adobe Acrobat that could compromise users computers if they open a malicious PDF document.

Adobe issued an advisory Thursday warning that its Reader and Acrobat software versions 9 and earlier contain a vulnerability that could allow attackers to take complete control over a system if the user were to open a poisoned PDF file. Adobe said it doesn't plan to issue an update to plug the security hole until March 11.

Adobe Reader and Acrobat users can significantly reduce their exposure to such attacks by disabling Javascript within the application. To nix Javascript, select "Edit," "Preferences," "Javascript," and uncheck the box next to "Enable Acrobat Javascript."

Also, you must  regularly update and patch your computer with Microsofts security updates as well as updates for other programs running on your computer. I recommend running an online scan from Secunia and follow its instructions for updates: (http://secunia.com/vulnerability_scanning/online ).



The past several issues have covered various aspects of pc security. I summarized those items in the last issue, which you can review by clicking on the link to Issue #6 on the left. In this issue, I am going to discuss what happens to files after you delete them and what you should do when you want them permanently gone.


When you delete a file from your computer (and it needn't be Windows, this is common to every type of PC), that file doesn't "go away," even if you empty the Recycle Bin. Rather, to save wear and tear on your hard drive and to simplify the operation, your computer just eliminates the record of where the file began. Think of your PC as containing a giant "shopping list" of all the files on its hard drive. Delete the canned peaches off that shopping list and the store doesn't actually get rid of the peaches. It just "forgets" that they are there. The space allocated to the peaches remains there until the store needs the space for something else.

There's good and bad in this. The good is that if you accidentally delete something you have a good chance of being able to get it back. The bad: So can anyone else.

If you're sure you want to delete those files for good, there's plenty of software for that, essentially replacing the recycle bin with the equivalent of a paper shredder that wipes any file you delete for good. If you install one, tread with caution: Once you delete something, even by mistake, there's no going back. Simple File Shredder is a good (and free) choice to check out.

Next month I'll discuss how to recover files you've accidentally deleted.


More Search Engine Tips

I've been focusing on Google tips over the past several months, but don't think that Google is the only way to search for things on the internet. You will get different results from different search engines. Some of the other popular search engines are:

Yahoo.com
MSN Search
AOL Search
ASK.com

If you're using a major search engine to find information on the Web, you're missing out on some of the best search experiences. With the help of a metasearch engine--a service that grabs results from multiple search engines--you'll find relevant results quickly. Some of the more popular "meta" search engines are:

Dogpile Search:Searches Google, Yahoo, LookSmart, Ask.com, MSN search, and more.
Clusty
IXQuick
Mamma
MetaCrawler

Then, there are the comparison shopping search engines:

Froogle - part of the Google family, this site is still under development.
MSN Shopping - a Microsoft company where you can compare over 36 million products from over 8,000 stores, all in one place.
MySimon - owned my CNET offers shopping recommendations, buying advice, and side by side price comparisons.
NexTag - is the leading comparison shopping site for products, financial services, travel, automobiles, real estate, education and more
PriceRunner - was designed to provide consumers with easy online access to specifications and prices.
PriceGrabber - comparison shopping beyond compare
TheFind.com - this unbiased "Product Ranking Engine" crawls over 500,000 stores to find over 150 Million products web-wide.
Shopping.com - this eBay company pioneered online comparison shopping and today is one of the fastest growing shopping destinations for a comprehensive set of products from thousands of trusted stores from across the Web.


Question of the month
This month's question is "My computer tells me I've run out of space on my "C" drive. What does that mean? Do I need to get a new computer?"

 

If your computer is letting you know that you've run out of space, it means that it has no more space to save any files. This happens quite a bit with laptops that are more than a couple of years old. Those came with hard disks that were quite small compared to what computers are coming with now. With todays technology, more and more we're using our computers for music players, video players, games, etc. Today's software programs are trying to do a lot more than they used to, so they also take up more space on the hard drive. Additionally, every time you visit a webpage, it leaves graphics and text on you computer. With all of the songs and movies that we install on our computers and software that is getting more bloated, it's no wonder we eventually run out of hard drive space.

What to do when your hard drive gets full? Initially, clean it. In Windows XP and Vista, click on Start, All Programs, Accessories, System Tools, Disk Cleanup. Select the drive you want to clean (C:) and click OK. A window will come up stating "Disk Cleanup is calculating how much space you will be able to free up..." This may take awhile so let it run. The next window will list "Files to Delete". At the top of that window, you will see how much space will be freed up by running Disk Cleaner. Check all of the boxes and click OK. Click Yes to perform these actions. The cleanup may take some time depending on what it needs to clean.

 

 

Next, go to your internet browser and clean out the history and temporary internet files. In Microsoft Internet Explorer, click on Tools, Internet Options,  General Tab, Under Browsing History, click Delete. You'll see items to delete. Make sure to delete the temporary internet files and history. In Firefox, click on Tools, Clear Private Data. Choose Browsing History, Cache, Offline Website Data.

 

 

Performing these steps should clean up quite a bit of your hard disk. If you find that you still need more space, remove some of the programs you find you really don't need. If this still doesn't work, you can upgrade your computer with a larger hard drive. You can probably triple the size of your drive for under $100.
