There are a lot of utilities that can be used to clean a computer. These do something more than the usual “Disk Cleanup” ($ cleanmgr), are easy to use with custom features and are faster too. Cleaning up your computer can improve its performance and ensure greater privacy. For a while now, I have been using Piriform’s CCleaner. It is one of the most comprehensive utilities of its kind.

CCleaner’s primary feature is the Cleaner. First, it will analyze the system, fetch the files that it is going to delete from the recycle bin, browser caches, other application caches, and many other obscure locations. The user can choose which areas to scan for and which to leave alone. Then the files can be deleted using any of the four secure file deletion options, but be warned that the greater the number of passes the fewer the chances of recovery if needed. There are many other customizations that can be made, like specifying the files and folders to be deleted and those to be excluded (apart from the usual set), the cookies to be preserved, and running from the command line.

CCleaner also has a registry cleaner than cleans the registry for any old or unclean or deleted entries. I think this feature can be made more robust. Be sure to save the registry before editing it.

Two other tools that come along are the “Uninstall” and “Startup” tools. The former can be used to uninstall programs. It is faster than the conventional “Add or Remove Programs” in loading the programs and also loads most programs unlike the regular option. The “Startup” tool can be used to disable or delete various startup processes, equivalent to the options provides by msconfig.

One other (unnecessary) feature I like about CCleaner is the way it displays the OS and the processor details when opened.

CCleaner is a regularly updated free software with new versions released every now and then. Download the latest version from the official CCleaner website. It is hardly 3 MB.

We have all heard of the Pirate Bay, the bit torrent search engine site. It was sued by some biggies of the MPAA like MGM Pictures and Sony BMG, and the case began its trial yesterday in the Stockholm district court.

A police investigation took place way back in 2006 and the current trial is considered a consequence. The trial is being closely observed by the world because its judgment has the power to determine the future of the Internet regarding copyright infringement laws and rethink where cyber law stands.

The Pirate Bay is a Swedish site that facilitates users by providing links to torrents. It is considered the world’s largest bit torrent tracker and with an Alexa Rank of 109, I can now imagine how popular the site has become.

The Pirate Bay has millions of supporters and I am not one among them. I respect, encourage and support open source, but I have no delusions that those who take part in copyright infringement are being Robin Hood-ish. Music, movie, publishing and software industries are largely impacted by piracy and I can feel the pain when someone takes my content without my consent.

Without meaning to make it a Super Bowl match, on which side are you?

Jason was kind enough to accept my guest posts for his blogs Microsoft Weblog and Uncover the Internet. These are my first guest posts ever: one about Microsoft’s involvement with Open Source and another about watching movies legally on Youtube. I hope you enjoy them.

Gmail is a pretty good mail service provided by Google which strives towards accurately catching spam, and is very successful in catching the phish. One thing that empowers the people behind Gmail is the volumes that Google sees.

The Google Enterprise Mail is apparently a much-in-demand service too and it has a Google Enterprise “spam squad” who welcome spam so as to analyze and counter them. Nearly a month after the new year started, they have posted a retrospective post “2008: The Year in Spam” which you may go through if you have time. Otherwise this summary will suffice.

Closing the McColo Network culled spam by 70% in Nov, 2008, but it has been growing at a rate of 156% ever since. The highest spam last year, however, was on April 23rd, where one undisclosed customer reported receiving 100 emails per minute per user. The unsurprising bad news is that, “All indicators suggest this trend (read increase) will continue as virus, malware, and link-based attacks become both more frequent and more ingenious.” Sigh.

What I observed in my inbox is backed by the report as another growing trend: “emailing spoofed news alerts with URLs that would link to a website hosting the virus.”

Watch out and defend yourself.

For the first time, Symantec Corp. publicly released a detailed report of its findings about the “Underground Economy” (cyberworld) through its observations between July 2007 and June 2008. Though this report was released nearly two months ago, I came across it only now.

Read the Symantec Report on the Underground Economy or listen to the corresponding Symantec podcast by Zulfikar Ramzan, the Security Technology & Response Technical Director.

Symantec estimates the value of total advertised goods on the underground servers as up to $276 Million and this figure is from only the underground they had access to. Mr. Ramzan said in the podcast how the actual size is extremely tough to estimate, what with the smartest of the criminals remaining in the underground of underground.

It is alarming and interesting to see how the underground economy functions, in ways similar to any other economy. The trends, I believe, will remain upward because cybercrime is still in its infancy even though there are already malicious but very smart people out there.

A person without any knowledge about cybercrime could start by getting access to any of the malicious tools like the Attack toolkits and Keystroke loggers. However, there are specialized roles within cybercrime each of which can’t be done by just about anybody.

Once goods or information are stolen, they are advertised, sold and resold.

Pirated softwares include desktop games, multimedia software, business software suites and OSs. Some of them could be offered for free to establish their credibility, but those with greater consumer demand are also often attached with malwares. The pricing of pirated goods is often proportional to identical trends in the genuine softwares.

However, according to the report, pirated softwares make only one-third of the underworld economy. Sensitive information is more popular. The above screenshot shows a table with the percentage-wise division of the top kinds of sensitive information that the cyber criminals are after. It sends a chill down my spine, especially with the 4th and 5th ranks.

An interesting tidbit: The United States hosted 41 percent of the total observed underground economy servers worldwide, while Romania had the second highest percentage at 13 percent of the total. Romania! Who would have guessed?

While Windows Live Writer is a wonderful blogging software that lets bloggers work offline, it is poorly documented. Ironical. On top of it, the Windows Live Writer blog, much like other Windows blogs has no search feature to check for help.

When a blogger posts a blog through Windows Live Writer, it also maintains a copy of the post on the local machine. For regular bloggers, that adds up to a lot of space with time. A “proper delete” through the Open –> Delete makes it clear that deleting a post is equivalent to deleting it from the local machine as well as from the blog.

Some might like the backup, but we won’t mind an option to delete posts from the machine alone, do we? I am currently using a dirty trick to get it done.

All the posts you are working on using Windows Live Writer are stored as .WPOST files in the folder “My Documents\My Weblog Posts” under two sub-folders “Drafts” and “Recent Posts”. Delete the posts you want from them.

There is also a “cache.xml” file in the “Recent Posts” folder. This is the file responsible for keeping posts on the local machine in sync with those on your blogs. It is better left alone.

Please let me know if there is a cleaner way to do this. I am still a beginner user of Windows Live Writer.

First Juan was not excited about this year’s MacWorld. Then he worried about Steve Jobs’ hormone imbalance, which I must say is something only Apple lovers are capable of. Now, after watching MacWorld ‘09, he decides that Phil Schiller’s keynote was just fine.

Jason, celebrating his three-year anniversary at Microsoft Weblog, sees a surge in Zune’s popularity since the 30GB Zune owners started experiencing widespread failure and Microsoft subsequently updating them about its fix. He still wants to buy Zune, but do you recommend it?

The last year can also be called “the year of Twitter”. The micro-blogging social media tool where each user answers the question, “What are you doing?” has gone viral so much so that there have been a billion tweets in 2.5 years since its launch. Latest news is breaking through Twitter already and the Internet dictionary put on a few pounds thanks to Twitter. At a time when the Twitterverse is speculating about whether Twitter would monetize or not, it is natural for miscreants to take advantage of Twitter to make some money themselves.

Here are three problems all twitter users are likely to face on Twitter:

Phishing: Twittersphere is abuzz with tweets about phishing, which prompted me to make this post. There is a phishing attack spreading across Twitter at this moment. It began with what is being called “DM Deception”. User A receives a direct message from User B asking them to check out some URL. You know what happens next. I didn’t face this yet, but I have seen compromised accounts among my followers tweeting messages like, “Check out this cute pic of yours, LOL…” with another URL.

If you suspect that you may have become a victim to a phishing attack, change your password immediately. If it is beyond salvation, bite the bullet and report the user as malicious. Twitter has so far been quick at suspending suspicious users.

Shortening URLs: I am not complaining but I expected this to be more rampant than what it is now. More URL shorteners like TinyURL, Tr.im, Snurl are crowding because of the growth of Twitter. A long URL is shortened to take fewer characters so that it can be shared through tweets. The trouble is that you have no idea about what you are clicking at. It could very well be some link spreading malware. What makes this worse is that these shortened URLs are too similar to be distinguished or remembered; you could click on the same bad link twice on your bad day.

A solution is to enable the preview feature. Tinyurl, e.g., provides a cool preview feature which when enabled shows what the URL redirects to (the original URL that was shortened) and then asks you whether you want to proceed to that site. I wish that all URL shorteners implement the feature.

Twitter Apps: Hundreds of apps are being developed around Twitter. Take a look at this list of Twitter Clients being used and you will know. All these expect your Twitter username and password to login. You might come across a new app that asks you to enter your Twitter username and password to be able to use it, and what if it steals your username and password? This might seem far-fetched but I don’t see why it can’t be done.

I tend to give any new app a day or so before using it, and I keep my ears open to listen to the grapevine until then. When my work depends on trying such apps I try it with a secondary account first.

As of now, I believe that the elite Twitter users are more prone to these attacks and have more to lose. That said, having started using Twitter only a couple of months ago, I find it immensely useful and would like to be prepared to face all possible annoyances. So what other problems do you think we might face?

I came across an amusing short film through one of my twitter friends, @stanleytang. The video has some wonderful visual effects, takes unexpected turns, and keeps us at the edge of the seat. Inspired by Transformers, what starts off as a harmless debate about whether the PC or the Mac is greater turns into a full-blown battle between… you will see what.

I am looking forward to the sequels. Tell me there are sequels. Dan Chianelli and Nick Granlee are the directors of the movie. The latter calls himself a digital impositor and you can find more of his videos on his website.

Follow me on Twitter.

We are still more than ten days from the new year, but a majority of the world has already started retrospecting the last twelve months and forecasting the next twelve.

Jayvee inspects the culture of FAIL on the Internet and finds that video advertising is going to decline. Actually, the rate of growth of online advertising has reached a saturation point even though online advertising itself is continuing to rise.

In these tough times, when the economy has been slowing down, Clair suggests that choosing Linux and open source software has become more necessary. For those who are already in that path, there is a free Ubuntu training course. Ubuntu is Linux for human beings, isn’t it?

A survey found that only 1% of people are using Google Docs, and many of those use Microsoft Office already. However, Colleen feels that the Microsoft’s stranglehold on office suites may be slipping away with Microsoft promising and postponing their next release and the availability of too many options for the users.

Juan says that 2008 is the year of iPhone, which is not very debatable in the user sense though this is also the year for RIAs, Twitter (@bsravanin) and cloud computing. But then, he is an Apple guy. :-) He also shares the offer that MacUpdate is having as a holiday promo. A good offer, far better than dreaming about the Apple 24″ LED display which is about $900!

Speaking of promos, Jason has a post about the Sears Wish Promotion, similar to the HP Magic Giveaway which has recently ended. There is already several Top 10 lists too, like the top 10 viral videos of 2008. I personally don’t like the fact that these lists do not consider the rest of the year that is still to be lived through. The more important news is, in case you haven’t already heard, that a serious security flaw has been exposed in the Internet Explorer and it is advised to not use it for financial and other sensitive transations of any kind.

While you wait for the security update, be sure to take note of the 8 security bulletins that Microsoft is ending the year with. Various OS users may want to check out the 2008 Service Pack 2 beta releases.
