This guide will help you to get rid out of viruses spread by USB Pen drives, Flash drives or Memory cards.
Most of the viruses are spread by pen-drives or its kind of devices because of built-in feature of Windows to autorun the file in pen-drives.

Problem:

When you connect the removable drive to your PC's USB port, Windows automatically try to dictate the 'autorun.inf' file if it resides on removable drive, which commands the file to be executed when autorun event occurs, but if autorun file execute the file which can be viruses than you should be worried about it.
As soon as you connect the drive, virus makes a copy of itself into your computer. It's done, virus enters into your computer.

Autorun file basically resides on the drive alone, not in any folders.
File name : autorun.inf
Properties: hidden with two level hiding attributes. May be read-only also.
Contents: i.e.
[AutoRun]
OPEN=abc.exe
This will execute the file 'abc.exe', which could be a virus.

Basically here, the file "abc.exe" will also be hidden with two level hiding attributes, such that you cannot see it directly on your drive, so you wont even know that it resides on your removable drive.

Diagnosis
:

To know that if "autorun.inf" resides on the drive including your hard drives, CD/DVD drives and other removable drives, follow this steps.

One simple way is,
-Right-click the drive, find 'Auto' or 'Autorun' option on the menu, if it is there, then there will be a "autorun.inf" file in your drive.

Another way is,
-In Windows Explorer, follow the path: Tools > Folder Options, click on it.

-In the folder option, in the 'View' tab, find the item, "Hidden files and folders", it will have two options, select the option "Show hidden files and folders".

-Remove the check sign from the item "Hide protected operating system files (Recommended)".

Now go to your drive, you will be able to see all the hidden files & folders onto your drive including "autorun.inf", if it is there. But if your computer has the after-effects of the virus named 'sal.xls.exe', than you wont be able to see the files, because it just resets the changes you have made in above step.

Solution:

You take care of your computer a lot, you update the virus definitions of your anti virus software. But some latest viruses cant be caught with it.

If you can see the file, 'autorun.inf ' on your drives, it may meant for spreading the viruses. So it is my recommendation that you must delete it immediately.

To stop spreading viruses by USB pen drives, flash drives or memory cards, the best way is to disable the autorun feature of windows.

You can do it by some registry tweaks, but the easiest way is here:

You will be required to install 'Tweak UI' Powertoys utility on your computer, which can be downloaded from here.

Download from any of the servers.
Server 1 : TweakUiPowertoySetup.zip, Size: 133 KB, Download Now
Server 2 : TweakUi.exe, Size: 147 KB, Download Now

Install it, If you are using Windows Xp, follow the path in Start menu:
"All Program" > "Powertoys for Windows XP" > "Tweak UI".

In window, which appears, select the items this way from the left tree.
"My Computer" > "Autoplay" > "Drives".

On the right side, all the drives appears with check boxes.

Remove the check marks for the drives, you want to disable autorun. My recommendation is that remove the check marks for all the drives including your CD/DVD drives.
Press OK. Thats it.


This is the another solution if your computer is affected by virus included in 'sal.xls.exe'.

Following are some after-effects of it.

-In Folder option, when you select the option, "Show hidden files and folders", and when you press OK, you cant see the hidden files or folders, even those resides on your computer.

Here is the solution for it, you have to do some registry tweaks.

-Go to Start > Run and type in 'regedit', press OK.

-Go to the following registry key:

HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL

-Delete the value CheckedValue. ( Its type should be REG_SZ and data should be 2 ).

-Create a new DWORD value called CheckedValue ( same as above, except that the type is REG_DWORD ). Modify the value data to 1 (0x00000001).

This should let you change the "Hidden Files and Folders" option.

Before I'm going to explain the real story of this boy, I wanna explain some facts.

In world of telephony and internet, it was the time, when there were no other players in the market to compete with BSNL, It was ruling the whole telephony market. The phrase 'Customer Satisfaction' wasn't there those days, but afterwards when other players jumped into the market, BSNL has to revamp the services.
The babus of BSNL had to think, how they can compete with other biggies in terms of services to stay on the top place in the market. Internet was one of the services provided by bsnl, but no broadband was there. Services other than 'dial-up internet' was not affordable for a middle-class people. But when other companies start to provide better Internet services, bsnl had to take step further and launched the 'Dataone Broadband'.

Dataone Broadband, today is the best Internet Service available in terms of speed and cost.
Other companies are there, which can provide fast internet connections, but the skims of them are not better than Dataone.
Plus point for dataone was the existing phone line, which customers were using just for phone calls and dial-up internet connections in those days.
Dataone uses existing phone lines for broadband internet connection, So initial cost of dataone is far less than the others, for a common man it was a boon.

Initially when launched, cost was much higher, although was succeed in urban areas but not much as of today.
To be online for whole the day, for youngsters was very costly, because it was eating bandwidth like two-day hungry man eats burgers. But as time passed, broadband rate slashed down and has been made affordable for everyone.

Now most of the Home PCs in urban areas which have internet, have broadband connections, having Dataone plans. People are ready to go online without worrying about limited bandwidth.

Most of the people are using 1 GB bandwidth limited plan, but if you are using 2.5 GB bandwidth limited plan with night unlimited bandwidth, the world would be in your home in just few clicks. 1 GB plan was good enough for the people who chat all the day, check emails, visit social networking sites, but there are some limitations which make this plan not much better for some other geeks,
You can chat whole the day, but when it comes to webcam chat, you have to bother about limited bandwidth. You can visit people's profiles on the site, but when it comes to watching his/her pictures, videos you have to think again about limited bandwidth.

But if you are ready to spend more on broadband, other plans are just awesome for you.
Unlimited plan for Rs. 900 per month for a collegian was a litter bit far, Although he/she can spend money for it by earning cash by doing other works.

So, a 2.5 GB limited bandwidth plan with night unlimited from 2 am to 8 am is the perfect one for the people who want to use internet without bother about the bandwidth, also want to download free stuffs like movies, songs.



Here is the real story of a boy, Vimal, one of my friends, owns a 2.5 GB limited bandwidth plan, and how broadband becomes a part of his life.

Most of my friends were equipped with 1 GB limited bandwidth Dataone plan including me, only one of us had a 2.5 GB plan.
Me and my friends are just crazy about Hollywood movies, no. of movies we have I will tell you later on.

So the guy, with 2.5 GB plan was like an angel for us, only if he download movies for us.
A single movie is about 700-900 MB in size. If this buddy download it in the day, the 700-900 MB would be slashed from 2.5 GB.
So it was awful to download movies in the day. So we had to think about the time period 2 am to 8 pm, which allowed us to download a single movie in one night without worrying about the bandwidth.
But my friend wasn't ready to wakeup in the night at 2 am. The thing was very simple, he just has to start download after 2 am, after that he can sleep up to 8 am in the morning. But he disappointed us a lot. He was not ready to download a single movie in whole month, I think this was due to his laziness for that.

But afterwards, Vimal buy a 2.5 GB plan. Now we don't have to request him for downloading movies, because now we got a real angel for movies.
This guy was ready to wakeup till 2 am just for his love of movies.
But how it can be possible for him to wakeup till 2 am? specially on daily basis?
Here is the answer, he just start to watch movie after 12:00 am daily, don't worry about ending of a movie, he watches movie just for time pass and wait for the stroke of 2 am by the clock.

For normal people, day changed at midnight, but for this buddy, it takes two more hours.
He manages to start download after 2 am.
Now-a-days, It doesn't take a whole night to download a single movie due to higher download speed, so he start to download 3-4 movies simultaneously, as a result, 7-8 movies can be downloaded in just 3 nights.

Now, can you imagine how much he download in the nights in a whole month? It is damn more than 75 GB.
So the fact is, a person who has just 2.5 GB limit for uploading/downloading contents, is downloading the data 30 times the given limit. He really sucks the BSNL. One more shocking thing is that, Vimal has downloaded more than 35o movies including 20 or something Hindi movies also.

Now we have a very large collection of movies on DVDs and HDs, which have been downloaded from the Internet.
In my friend circle, everyone has more than 30 downloaded movies in the Hard-disk at a time.
We all don't require to download, we just have to request this buddy for it, on the next day our requested movies will be there on our hard-disks, on our PCs.

For sharing movies we don't have a LAN implementation, because we live far from each-other.
We don't burn CDs/DVDs to share movies with friends.
We just copy the movies direct to the hard-disks.
All of my friend are now master in that stuff. But before this era, some of the guys were not ready for opening the cabinet and removing the hard-disk from it. But the hunger of watching movies motivated them to do the same.

It was a time when we hardly have a single movie on CDs to be watched once in a week. We have to rent or to buy CDs from the market.
But afterwards, we have a large collection of Xvid/Divx formatted movies with DVD quality of video and sound.
Now this buddy download more than 100 movies per month.
After downloading 20-25 movies, he invite us to copy the downloaded movies, we hardly watch 5-6 movies from our collection of more than 30 movies on our HDs. We have to delete all other movies without watching, because new movie stock is always ready with more than 20 movies every week.

This was the story of my friend, a Boy, who never sleeps before the stroke of 2 am in the clock.

Apart from that, we have a large network in my city, movies are passing from one end of a city to the other end via our network.
No, there is no wired network, its a wireless network without transmitters, receivers and routers.
Its a network, which can handle more than 30 GB of data to be transmitted at a time by just one packet! Its a packet that contains hard-disk. Hard-disk is passed to one location to another location by us.

All movies from Hollywood are not released in India, we cannot watch other movies.
Movies we watch are those which are aspirants, comedies, about glory, are not released here.
Why? these movie are not released in India is the question, I think the answer is, most of the Indian love to watch movies that contain actions (done by Indian hero, not by a Hollywood star), love to watch love stories (he doesn't aware of other great love stories films made out of India). But why should I discuss this thing here. Its my own opinion.

We download some good Hindi movies also. But other movies cant be compare to Hollywood movies we watch in terms of directions, stories.

It's the power of Dataone broadband. You can buy other broadband connections, but you cannot find plan in other companies, which provides 2.5 GB upload/download limit with unlimited uploads/downloads in the nights with up to 2 Mbps of connecting speed and more than 90 Kbps of downloading speed.

Story I mentioned above is not of only a single person in India, there are lots of people in my city and in India who are sucking BSNL.

You can call us mad-men for movies, yes, we are.

Google AdSense is fast becoming the preferred way for people to earn an income online. Forget eBay and multiple affiliate programs - Whether you are a work-at-home mom trying to make a little extra cash or an Internet entrepreneur with hundreds of monetized websites, AdSense is truly the easiest way to earn money.

Simply sign up for a free account, grab your ad code and paste it in your site. But here's the amazing thing - no matter how much money AdSense is making for you right now, a few simple tweaks can increase that amount considerably. And I should know, after learning about these tricks, I more than doubled my AdSense commissions!

The self-proclaimed AdSense gurus and experts are sharing this insider knowledge, for a fee. You can learn all these secrets from them, as long as you buy their e-book, sign up for their seminar or purchase their newsletter. But I'm going to share all their AdSense tricks for free. Here they are:

1) Color code your ads to match your web site palette *exactly*. Don't use frames around your ads. Instead, in the AdSense code generation interface, make sure you choose the same color as your page background for the ad frame and the ad background.

When choosing the ad heading colors, match them to the *exact* color of your page headings. Use the exact same ad background shade as your page background. Use the exact same ad text font and color as the text on your pages. You can see an example of this color-matching on my search engine advice blog - notice the 4 link ad unit and skyscraper text ad unit on the left hand side under the headings Ads by Google as you scroll down the page? The link and text colors are identical to the color palette used throughout the rest of the page.

Near enough is NOT good enough. If you can't quite get the color matching right, use Google's built in color palette together with the RGB to HEX or vice versa color converter on this page. That handy little tool was a life saver for me.

This is probably the one single tweak that made the most difference to my commission levels.

2) Try not to use the traditional horizontal banner style or leaderboard image ads because people are blind to them.

3) Use Google's own AdSense optimization tips and visual heat map to assist you in deciding where on your page to place your AdSense ad code.

4) Research competitive keywords using a keyword research tool such as Keyword Discovery or grab a list of the most popular keywords from various sources and use them in your web site pages where relevant. This article is a good source of frequently searched keywords. Targeting popular keywords should trigger AdSense ads on your pages that utilize those keywords. The more popular the keyword or phrase, the higher AdWords advertisers are generally willing to pay per click for it so the higher your commission on those clicks.

5) Incorporate the AdSense code into your page so that the ads look like a regular part of your site. You can see an example of this on the Internet Dating Stories site where link ads are incorporated within the regular left hand navigation of the site under the heading "Sponsor Links".

6) Use Google's new 4 and 5 link ad units wherever possible. They seem to have a much higher Click Through Rate (CTR) than regular ad styles. You can view all the AdSense ad formats here.

7) Place images next to your ads to attract the eyes. You can see this in place on the search engine article library page at the bottom where 3 images draw your attention to the bottom of the page. But be careful here - the use of arrows or symbols enticing viewers to click are NOT allowed by Google and publishers may NOT label the Google ads with text other than "sponsored links" or "advertisements".

8) Use the full allowance of multiple AdSense ads on each of your pages - 3 regular AdSense ads, plus 1 link unit. Use careful placement of these ads so they blend into your site and don't distract from your content. Clever use of this allowance can be seen on this page about bad Internet dating stories where you see:

- 1 horizontal 4 link ad unit towards the top of the page under the first paragraph
- 1 vertical skyscraper text ad unit about halfway down the left hand side under "Sponsor Links"
- 1 vertical skyscraper image ad unit down the left hand side under "Sponsor Links"
- 1 horizontal text banner unit at the bottom of the page with images above each ad.

You can also include 1 AdSense referral button in addition to the 3 other units.

9) Tailor your page content to a particular niche or focus. Page content that is tailored towards a specific theme is more likely to trigger AdWords ads that closely match the content and are therefore more likely to interest your visitors and inspire them to click. Do not create pages merely for the sake of placing AdSense ads. Visitors (and search engines) can see through this ruse in an instant.

10) Use custom Ad Channels for each of your ad placements, for example, "Top 5 Link Unit Blue Palette" or "Left Side Navigation Image Skyscraper" etc. Tweak, track and measure the success of each of these custom channels so you know what gives you the highest CTR. Some ad formats and colors will work better than others, but you won't know which until you test, test and test some more!
