Uninstall - Trend Micro Titanium Antivirus Security Suite

Uninstalling the Trend Micro Titanium Security suite has not been a pleasant experience for me. The usual techniques below don't work.

  1. Uninstall by going to "Programs and Features"
  2. Stopping Trend Micro services from the "Services". Even "Run As Administrator" would not allow the service to be stopped.

At the moment I have found a few useful links from other sites such as:
  • http://esupport.trendmicro.com.au/solution/en-us/1037161.aspx
  • http://esupport.trendmicro.com.au/solution/en-us/1058879.aspx
  • http://esupport.trendmicro.com/solution/en-US/1059018.aspx
  • http://forums.cnet.com/7723-6132_102-552546/trend-micro-security-won-t-uninstall/
One trick that seemed to work, thanks to the links above, is go to the START button on Windows (sorry Windows 8), 
- look under All Programs 
- look for Trend Micro folder
- go to something like More Tools and Help
- look for something like: Trend Micro Diagnostic Toolkit - run this.



Group Feature selection -a Binary Way


Suppose there are T distinct types and each of these types is labelled as 1,2,3,4,....,T. Let any of these types be represented as t.
And suppose we want to have various groups and each group is a combination of types. There are G groups in total and each of these groups can be labelled as g = 1,2,3,....G.

Each group can be composed of types as the following example:
g=1 has types  {2,3}
g=2 has types {1,2,3}
g=3 has types {1,2}

Then suppose that for each group g, it is required to randomly select a type which belong to the group.
Here is a method that is designed to be general and although may not be the the most efficient, should be efficient enough for small T.
The types are represented as binary as follows. Example with T=3
t=1 -> 001
t=2 -> 010
t=3 -> 100

The groups can be represented by combining the binary representation for the types. So using the example of the groups above, if g=1 has types {2,3}, then the group is the binary sum of the types:
   g=1 -> 010 +100 = 110
   g=2 -> 001 + 010 +100 = 111
   g=3 -> 001 + 010 = 011

Now for a particular group, it is required to select types which belong to that group. However for general efficiency, it is desired NOT to distinguish between any groups while selecting the random types. So there will be some wastage in this procedure, but it should be fast.

So here is the general random selection process to select any type t from 1....T. Let r be a random integer number from 1....T. Construct a binary representation of the random number, such that:  b=2^(r-1).
The table below shows the representation for various random numbers:
r=1: b=0 -> 001
r=2: b=1 -> 010
r=3: b=2 -> 100

To apply the random selection, simply apply the AND operator on r and g. So using the example of g=1->110, the combination with each of the random numbers would yield the following:
g->110 AND r->001 => 000 no type is selected
g->110 AND r->010 => 010 type 2 is selected
g->110 AND r->100 => 100 type 3 is selected

This algorithm can of course be made more efficient, but that is left for another bright person to accomplish. The present algorithm is efficient already due to use of simple random integers and binary operations and avoiding the use of decision logic like if-else.

Where to get free graphics

Graphics or pictures or images are very useful when we want to illustrate something on our webpages, blogs or other work. It is very easy, but sometimes not right to simply search for images on the internet and use them without permission. There are however, places on the internet that allow pictures to be used for free.

The aim of this post is to put up a list of sites that allow users to use the images for free.

Now for some new stuff. Some tools that can be downloaded and used are:


Google and download: TDSSKiller
- Start tdsskiller - Run as Administrator.
- Click on Change parameters.
- Check all options except "Loaded modules" and click OK.
- Then click on Start scan.
- When threats are found, choose the Skip option for all of them, instead of deleting.
- To open the log file, click on Report. Or it can be found in :\TDSSKiller.<version_date_time>_log.txt


Google and download: Farbar Recovery Scan Tool.
- Start FRST - Run as Administator.
- Select the option Addition.txt as well as others selected by default. Press the Scan button.
- FRST will create two logs - FRST.txt and Addition.txt - in the same directory the tool was run from.

How To Uninstall Pokemon Trading Card Game

The Pokemon Trading Card Game, is not so easily removed.

It may happen that your beloved one installed this Pokemon Trading Card Game without your awareness. The first thing any Windows user would do nowadays would be to go to the:
Control Panel -> Programs and Features -> Uninstall -> Pokemon Trading Card Game.
..... or something similar depending on the version of Windows XP/Vista/7/8/etc

Error: a ''property.USER_profile'' error

However, some may encounter an error message above during uninstallation. There are several options.


Two of the recommended tools are:

Revo Uninstaller
CCleaner
See http://xtechnotes.blogspot.com.au/2011/07/links-to-free-software.html for the above and similar tools


The way without using any software is the following.
1. Go to Control Panel -> Programs and Features
2. Scroll down the list of programs until Pokemon Trading Card Game is found.
3. Do not click the uninstall button above. Instead at the line item that says "Pokemon Trading Card Game", right-click and then choose Change or Repair something similar.
4. Then when a Window pop-up, click on the Uninstall button.
5. This uninstall should complete properly. If not, check out the software mentioned above. The other alternative is to boot into Windows Safe Mode and uninstall there.

Migrating WordPress Blog

This post is also posted at http://travel4work.wordpress.com/
Migrating WordPress from <yoursite>.wordpress.com – which is a free service – to another site that you are paying for such as <yourdomain>.com/<yourNewWordPressHome> is very easy and it is all done through WordPress.
In this situation, my new website has Fantastico and it allow WordPress to be installed on my domain very easily – few clicks of buttons. Now assume both <yoursite>.wordpress.com and <yourdomain>.com/<yourNewWordPressHome> are running, here are the instructions.
1. Go to <yoursite>.wordpress.com and login there.
2. Go to the classic Dashboard.
3. On the left panel, go to Tools – Export.
4. Choose to export “All Content” and when asked, save the XML file to your PC.
This XML file presumably contains all the data for the two WordPress to communicate.
There are lots of pictures in my original WordPress site, but the XML file is only over 100kB, so obviously the Contents are not being saved, ie not needed.
1. Now go to the new <yourdomain>.com/<yourNewWordPressHome> site and login.
2. 2. Go to the classic Dashboard.
3. On the left panel, go to Tools – Import.
4. At the Import page, choose the WordPress option, and you will be asked to install the plugin called WordPress Installer. Go through with this.
5. Then click on Activate Plugin and Run Importer.
6. Click the button to choose the XML file to import from.
7. In the Import WordPress page, choose Import Author and “Download and import file attachments”.
8. You can now go back to the original site and just manually check the old settings, and apply the same settings to the new website. Some example of this to consider are:
a) Appearance – Themes – search for the same previous theme using the search bar and install
b) Appearance – Widgets – Text – Add your text, including Google Adsense code.
