I would suggest getting a virus program such as AVG from Grisoft. They have a free version available. It works great. It will detect any virus you might have and heal any it can. Those it can't heal, either turn off system restore or for some you can remove with an alternate program that AVG has developed:
To remove I would suggest visiting the following URL from Grisoft/AVG: grisoft.com
I would suggest following its instructions to the letter. If you do, you can then run AVG again and the Virus will have disappeared.
Good Luck!
This is a very open ended question. There could be many causes for such a problem. Generally when I see a problem of this nature start happening out of the blue without any intentional changes to the system it's usually spyware, adware, or similar applications eating up memory and crashing Internet explorer. I would start by trying to determine if you have such programs running. You can view the tasks running by the keystrokes ctrl-alt-delete. Depending on which OS you have you may have to click "Task Manager" option if you're running 2000/XP otherwise it will automatically bring up the current tasks. You should do this immediately after boot up of your system to see what normally is running. In Windows 9x/Me all you are required to have running is "Explorer" and "Systray" you can "end task" everything else and you machine will run just fine. Of course some of those programs may be things such as viruscanner, of which hopefully you have, and soundcard applications, CD writer applications, etc. If you are computer literate enough you can write down each task showing and successfully search for the items online to determine there purpose. There are many spyware/adware apps that appear as Bargain (bargain buddy), bxx5, among others. Also viruses may show up as a task. If your not sure what the tasks running are try the internet. Someone has written about it before. If it's spyware/adware you can probably find out how to remove it from there as well. Good Luck, -Shawn

3. Run Malwarebytes Anti-Malware
4. Run the anti spyware removal programs spybot

Answer:
Yes, the question was what Trojan horses do to your computer, not how to remove them.
There are various Trojans out there. They carry this name, because their job is to infiltrate your system without being detected. This can be done by reediting your registry to fool security software, or if they tag along with legitimate software.
In any case, they are there to harm you in some way. One type of Trojan opens up backdoors to your security so that it can install other harmful processes along the right. Others will keep track of your keyboard input and send the data off to hackers who will steal from you. I hope this is useful.

How do you fix your computer after a virus has deleted some files from windows?
What to do if your computer is infected with a virus.
Sometimes even an experienced user will not realise that a computer is infected with a virus. This is because viruses can hide among regular files, or camoflage themselves as standard files
There are a number of symptoms which indicate that your computer has been infected. If you notice "strange things" happening to your computer. Your computer freezes frequently or encounters errors.
Your computer slows down when programs are started.
The operating system is unable to load.
Files and folders have been deleted or their content has changed.
Your hard drive is accessed too often (the light on your main unit flashes rapidly).
Microsoft Internet Explorer freezes or functions erratically e.g. you cannot close the application window.
What you should do if you notice symptoms of infection.
Disconnect your computer from the Internet.
If your computer is connected to a Local Area Network, disconnect it.
If the computer cannot boot from the hard drive (error at startup), try to start the system in Safe Mode or from the Windows boot disk.
Before taking any action, back up all critical data to an external drive (a floppy disk, CD, flash memory, etc.).
Install antivirus software if you do not have it installed and download the latest updates.
Perform a full system scan.
In the vast majority of cases, personal computers are infected by worms, Trojan programs, or viruses. In most cases, lost data can be successfully recovered.
A good antivirus solution will provide the option to disinfect for infected objects, quarantine possibly infected objects and delete worms and Trojans. A report will provide the names of the malicious software discovered on your computer.
In some cases, you may need a special utility to recover data that have been corrupted. Visit your antivirus software vendor's site, and search for information about the virus, Trojan or worm which has infected your computer. Download any special utilities if these are available
Unfortunately, some viruses cannot be removed from infected objects. Some of these viruses may corrupt information on your computer when infecting, and it may not be possible to restore this information. If a virus cannot be removed from a file, the file should be deleted.
If you cannot boot from your hard drive (error at startup), try to boot from the Windows rescue disk. If the system can not recognize your hard drive, the virus has damaged the disk partition table. In this case, try to recover the partition table using scandisk, a standard Windows program. If this does not help, contact a computer data recovery service. Your computer vendor should be able to provide contact details for such services.
If you have a disk management utility installed, some of your logical drives may be unavailable when you boot from the rescue disk. In this case, you should disinfect all accessible drives, reboot from the system hard drive and disinfect the remaining logical drives.
Recover corrupted files and applications using backup copies after you have scanned the drive containing this data.
Check the integrity of the file system on your hard drive (using CHKDSK program) and repair file system errors. If there are a large number of errors, you must backup the most important files to removable storage media before fixing the errors.
Use other standard Windows tools, for example, the scandisk utility.
After you have removed the infection from your computer.
Perform a full system scan and if you are using XP, make sure system restore is turned off or you might infect your computer all over again.
Make sure that you have appropriately configured antivirus software installed on your computer.
Re-connect your computer to the Internet........

Who might find the information recorded in the Dr Watson log file or dump file useful?
describe the purpose of the dr.watson utility
Win32 is the commonly abbreviated form of "Microsoft Windows 32-bit Operating System API," which means that the application was compiled to run on a 32-bit version of Microsoft Windows. There are several versions of Microsoft Windows that support 32-bit code, so the code must still take care to check the OS's version to make sure it is compatible with that version of Windows.
A virus that has an assigned name that includes Win32 targets Microsoft Windows environments capable of running 32-bit code. A program written in Win32 C++, similarly, is written in, and compiled by, a version of C++ that will compile into a 32-bit Windows executable file or shared library (.DLL). This code may be able to run on any version of Windows from Windows 95 onward, although most modern programs require at least Windows XP Service Pack 3.
What are the examples of botnet?
A botnet is a network of "zombie" computers all connected together by a hacker. Zombie viruses are a type of malware that infect a machine and then take it over without the user's knowledge (think of a zombie from the Walking Dead). The virus then distributes itself by means of email or social media sites like Facebook or other sites like MediaFire. The virus creates an email with itself attached to it, and then sends itself to ALL of the people in your contacts book on email or your friends on Facebook. When your friend clicks on the infected message, they too become a zombie and part of the botnet.
