- Trojan virus is known to be tricky. One of its characteristics is hiding the real file and pose a fake one, which is an executable file that carries a virus.
- Worm on the other hand is a malware that keeps on duplicating itself. Sounds great, the Trojan hides the data, front the Worm as the real one and once executed, you know what will happen next.
How it infects computers?
A simple insertion of infected flash drive into your PC will get your computer infected, immediately and vice versa.
How effective is antivirus against it?
Unfortunately, not all antivirus can detect and remove shortcut virus. But there are handful can do, to mention a few, trojorm removal tool, smadav, and usbfix.
Are you worried? I have good news for you! In less than a minute, you can easily remove, terminate, and prevent shortcut virus from your computer by yourself. YES! All you need is to follow the step by step guide below.

Files and folder shortcut.vbs and .lnk will look like just your ordinary files such as; word processor, presentation, folder, audio, and video files.
Flash Drive shortcut.iniand .exe makes an imitation of your flash drive consolidates your real data into one folder and hide it.
First thing to do
The best thing you can do is to make-it-a-habit, not to open your portable devices or hard drive via autorun or on “My computer”. See the below lists:
- Do not open your Flash Drive via autorun and on My Computer.
- Open your Flash Drive and Hard Disk by right-clicking it, then click explore or type its drive letter in the windows address bar to prevent any script from running.
- Follow this, how to unhide files and folder hidden by the virus. To unhide your hidden data and avoid executing it.
Method 1: remove shortcut virus using Trojorm Remover Tool
1 You need to download the trojorm remover tool and Fix folder. Once downloaded, extract it using WinRAR or any other file decompressor.2 Then, make sure that you run trojorm remover tool inside your flash drive, wait until the scan is complete and press enter.
3 Next, copy and paste the fix-folder.vbs (this is a good .vbs file) inside your flash drive, HDD, SSD, and external drive. Right-click it, choose open with and select notepad. Look for the cDrive = “H:”, change it according to your drive letter (ex. E, F, G and so on). Then exit notepad and save.
4To fix and unhide your files, run the fixfolder.vbs by right-clicking it. This time open it with Windows Based Script Host.
5 You must see a dialog box confirming that everything is fixed.
Method 2: remove shortcut virus using registry
Please take note that this guide is for advanced users only. I will not be held liable for whatever consequences that may take place after following this guide. I am not trying to frighten you but one mistake may affect your PC’s normal operation.
1 Press the windows key + R, type “regedit” to enter the registry.
2Navigate throughhkey_current_user / Software / Microsoft / Windows / CurrentVersion / Run. Normally, you shouldn’t see any key except the default as you can see in the image below. Any key that is unusual such as wxckyz , ouzzckky and others that end with VBS, INI, LNK and EXE extension are safe to delete. However, this is a case to case basis, do this in your own discretion. Besides you are the only one who knows what software you install on your computer.
3 Press the Windows key + R again, type “MSConfig” click “OK“, in “Startup” tab uncheck everything except your antivirus. Click “OK” and “Restart now”.
Fix-folder access denied error
Solutions:
Open fixfolder with notepad, see to it that you change the drive according to your Flash drive and hard disk drive letter.
What if you did everything right, from changing drive letter and typing the attrib command accurately as it is and still receive the access denied error?
Run chkdsk command using CMD. If you don’t know how to do it? Please visit this guide Windows detected a hard disk problem.
How to clean, delete and remove stubborn shortcut-virus from extremely infected PC, computer, laptop, notebook, and other portable devices permanently?
You followed the virus remover guide above and found it helpful. In fact, your shortcut-virus problem is now solved. However, after plugging again your Flash drive, external hard drive (HDD) and SD card it became infected again. Why this happen?
Reason: Your computer is extremely infected by shortcut-virus.
Solutions: You should clean your PC first and protect it before inserting any of your storage devices. How?
- Download RKill and run it. To stop any malicious processes.
- Download RogueKiller and run it as well. To remove any variants of trojans.
- Download Malwarebytes , install, update and run a scan. For more malware removal that RogueKiller might missed.
- Install SmadAV Antivirus. A finishing touch, this also removes Bundpil.Shortcut-virus and act as computer shield against it. Thus, preventing future infections.
Note:Please do not restart your PC until you finished installing SmadAV antivirus.
How to prevent shortcut virus from coming back?
Install SmadAV as your primary defense and a good antivirus. Then do a weekly scan with Malwarebytes, for better protection. Do not let anyone insert portable devices into your computer unless it is virus scanned and found safe to use.

Wireless communication with PC and Arduino board using bluetooth

PLEASE NOTE: this tutorial was written for Wiring but can easily be translated to arduino, just remember the rx and tx pins in arduino are 0 and 1 respectively.
See also this tutorial for using the BlueSmirf bluetooth device with Arduino.
Normally you would use a serial USB cable connected from your computer to your Wiring board for receiving data sent from a computer running processing to your board.This tutorial demonstrates how to execute this same process, but wirelessly using Bluetooth. We will test this by being able to turn an LED on/off wirelessly. You will need to use an adaptor to power your board for this tutorial. This tutorial covers communication from the computer to the board; not from the board to the computer.
Equipment:
You will need a Bluetooth Dongle for you computer and Bluetooth Modem for connecting to Wiring board. We specifically used the following(http://www.sparkfun.com/commerce/product_info.php?products_id=150 and http://www.sparkfun.com/commerce/product_info.php?products_id=158).This tutorial was developed for a computer running Windows XP Service Pack 2 (which has included Bluetooth support). It has not been tested on Macs or Linux.
Process:
Step 1. We firstly need to install the Bluetooth module onto the computer and install the drivers. If the module came with a CD, put this into your CD-ROM drive and then plug the module into one of your spare USB ports. Windows should automatically detect the device and if it asks for drivers, point to the CD-ROM drive. Once the drivers have been installed, Windows may need to reboot.
Step 2. Once your computer has rebooted, plug your Bluetooth module in (if it isn't already). A Bluetooth icon should appear in your taskbar (Windows XP SP2 has this Bluetooth support feature). Your Bluetooth module is now set up and running as a serial port. Now we need to set up the modem on the wiring board.
Step 3. We are going to create the setup in Figure 1. First of all connect your LED to your wiring board on whichever pin you want EXCEPT pins 2 or 3 (we have used Pin 8 in this tutorial). See this example for how to connect an LED (http://www.wiring.org.co/learning/examples/led_blinks.html). Once you have connected your LED to the board it is time to connect your Bluetooth modem. The Bluetooth modem we are dealing with has 4 labeled pins, PWR, GND, Rx and Tx. It is pretty straight forward: connect the PWR pin to the 5V pin on Wiring, connect the GND pin to the GROUND pin on wiring. Then connect the Rx pin to the Tx pin of Wiring (digital pin 3) and connect the Tx pin to the Rx pin of Wiring (digital pin 2). Once it is connected then plug your AC adaptor into the board, if everything is connected right a small green LED will start blinking on the Bluetooth modem.
Step 4. Now we need to set up a connection from the computer to the Bluetooth modem. With your Bluetooth module plugged in, double click the Bluetooth icon in the task bar and select �ADD� a device. It should find a device called BlueRadios � which is your modem. Select to connect to it. It will ask you for a passkey. The passkey for the Bluetooth modem we used is �default� (see http://www.sparkfun.com/datasheets/RF/BlueSMiRF_v1.pdf). If you used a different Bluetooth modem to the one we used, you will need to consult the product documentation to find the passkey. Once you have entered that passkey your computer will now remember that Bluetooth modem and be able to communicate with it now and in the future.
Step 5. We need to now find out which COM port our Bluetooth communication is on. Double click on the Bluetooth icon in the taskbar again and select the BlueRadios device from the devices tab, then click the COM Ports tab and take note of the port number the Bluetooth connection is using. In our case, the COM port is COM7
Step 6. Now that you have connected all your components, you need to upload your program to the Wiring board. YOU NEED TO USE A SERIAL CABLE TO UPLOAD YOUR PROGRAM � YOU CANNOT USE BLUETOOTH WIRELESS TO UPLOAD PROGRAMS TO THE BOARD. YOU ALSO NEED TO DISCONNECT THE RX AND TX WIRES FROM THE BLUETOOTH MODEM WHILE YOU UPLOAD. The code for the program we use is attached below. Once you have connected the serial USB cable, upload your program. Once it has uploaded successfully, reset your board and remove the cable.
Step 7. Now we need to configure the processing code. The code we used is attached below. You need to find out which number in the array the Bluetooth COM port is. Run the code once and take not of the COM ports which appear in the output pane. Eg. COM1COM3COM7In our case, the Bluetooth was connected to COM7, which is the number 2 position in our serial array (COM1 = 0, COM3 = 1, COM7 = 2). So we update the processing code to the following so it will use the Bluetooth connection to send serial data. Once you have updated this code, run the program again (see Step 8).
Step 8. After you first run the program, the computer will establish a connection with the Bluetooth modems � you will see a red light begin to blink on the modem � it will finally stay red once it has established a connection but may take about a further 10 seconds before it can receive data. The connection process will take about 15 seconds all up. After about 15 to 20 seconds, your processing program will now be connected to the Wiring board wirelessy. Now press the buttons on the processing interface and watch the LED turn on and off.
Code:
Wiring code � this code will wait for signals from processing. When it receives a H signal, the LED on pin 8 will turn on. When it receives an L signal the LED on pin 8 will turn off.
Wiring code |
char val; // variable to receive data from the serial port int ledpin = 8; // LED connected to pin 48 (on-board LED) void setup() { } void loop() { } |
Processing code � this code creates two buttons. When the left button is clicked it will send an H signal to the board and turn the LED on. Or if the right button is clicked it will send an L signal to Wiring board to turn the LED off.
Processing code |
//import class to set up serial connection with wiring board import processing.serial.*; Serial port; //button setup color currentcolor; RectButton rect1, rect2; boolean locked = false; void setup(){ } void draw(){ } void update(int x, int y){ } class Button{ } class RectButton extends Button{ } boolean overRect(int x, int y, int width, int height) { } |
