del.icio.us

Have you visited del.icio.us? Its a social bookmarking website.

A social bookmarking website lets you save your bookmarks online. You can access them easily from anywhere on the Internet- from home, work, a library, or on a friend's computer.

It lets you share your bookmarks with others on the Internet - with your friends, co-workers, fans etc. It also lets you to save private, non-shared bookmarks, if you want.

It also lets you discover sites that others have found good. You can easily see which websites others have bookmarked for a topic. For example, if you are looking for sites regarding CNC programming, simply search for the tag 'CNC' in bookmarks of people world-over. You will be getting sites that others have found good for information on CNC.

Rather than organise your bookmarks in folders, del.icio.us uses a concept of tags that you will get used to quickly and will find very beneficial. "Tags are one-word descriptors that you can assign to your bookmarks on del.icio.us. They're a little bit like keywords..." For more information on tags, visit their help page on tags.

For more information on how saving bookmarks to del.icio.us works, you can visit their help page on saving bookmarks.

There are numerous social bookmarking sites to choose from.
BTW, did you notice that del.icio.us is simply the word delicious with two dots in between?

HijackThis

HijackThis is a must have tool for advanced users. TrendMicro's website says:

"HijackThis™ is a free utility which quickly scans your Windows computer to find settings that may have been changed by spyware, malware or other unwanted programs. HijackThis creates a report, or log file, with the results of the scan.

IMPORTANT: HijackThis does not determine what is good or bad. Do not make any changes to your computer settings unless you are an expert computer user. ... Not an expert? Just save the HijackThis report and let a friend with more troubleshooting experience take a look."

So HijackThis lists all installed browser add-ons, buttons, startup items, search engine settings etc. If you find something that is causing problems, you can easily remove them using the tool itself.

Here is what a typical log will look like:

If you do not understand fully what to do, but are having a problem with your PC which you suspect is due to a virus/spyware, you can visit so many forums that help you see what is wrong.

Hardware, Software, Malware

What is Malware? Here is what Wikipedia says:

"Malware is software designed to infiltrate or damage a computer system without the owner's informed consent. It is a mix of the words "malicious" and "software". The expression is a general term used by computer professionals to mean a variety of forms of hostile, intrusive, or annoying software or program code."

The variety of hostlile, intrusive or annoying software includes: worms, viruses, trojan horses, spyware, bad adware etc.

How can you prevent your computer from being damaged by malware?
  1. You MUST have an Anti-Virus tool
  2. The Anti-Virus must cover your E-mail and Chat too
  3. Have a firewall turned on
  4. Use McAfee SiteAdvisor to keep you out of bad sites on the net
  5. Use a non-administrator account for email and browsing.
  6. Do Not Download from unpopular/unfamiliar sites. If you are looking for freeware or shareware versions of popular programs, stick to tucows.com, downloads.zdnet.com and download.com.
