How to get rid of a trojan?

Question

Got a notice that there was a trojan from norton internet security and it said threat was removed and 10 minutes later it said it detected another trojan but did nothing and I cant get it to give me the option to remove the trojan. This all started after I did a scan for trojans from a people pc web site.
I am having problems with my pc. I get redirected when i put in a search, like in google i put in security, my results come up fine but when i click on the link i get sent to other sites, some for finding mates, others are offers for various things, but usually redirects to many differnet sites. i will have to click on the link several times to get it to come up. what do i do. Looking for trusted site that is easy to use.

Answer 1

well as you hadn't told what the trojan was, it's difficult to say how to erase it. however if it's troja and not virus, you need an antispyware to fight it. i would recommend you spybot http://www.2-spyware.com/review-spybot-search-and-destroy.html

Answer 2

This procedure works for all Malware. Use any AntiVirus or AntiSpy program you choose.

ewido is the best Trojan remover available.

Download and Update Ewido (now called the AVG Antispyware). Do not run:

http://www.ewido.net/en/download/


TEMPORARILY SHOW HIDDEN FILES AND FOLDERS.

1. Click Start, and then click Control Panel.

2. Click Appearance and Themes, and then click Folder Options.

3. On the View tab, under Hidden files and folders, click "Show hidden files and folders", and clear(uncheck) the "Hide protected operating system files" check box.

IMPORTANT: Files are hidden by Windows for a very good reason. It is not wise to experiment with these files. Unfortunately, to successfully remove modern spyware we must turn this protection off temporarily. Please turn the protection back on when you have finished cleaning your system.


EMPTY INTERNET EXPLORER BROWSER CACHE:

1. On the Internet Explorer Tools menu, click Internet Options.

2. On the General tab, in the Temporary Internet Files section, click the Delete Files button. Select the Delete all offline content check box in the confirmation dialogue box that appears, click OK. Click OK again.

RESTART IN SAFE MODE:

To do this you need to hold down or repeatedly tap the F8 key while the computer is booting (when the computer is displaying a black screen with white text). When the boot menu appears, use your keyboard arrows to select "Safe Mode."

Safe Mode can look quite ugly. The color may look bad, and all of your desktop icons will be very large. This is normal.



START THE SCAN WITH YOUR PROGRAM(S).



When the scan and removal are completed REBOOT COMPUTER. This will restart you in normal mode.

RESET HIDDEN FILES AND FOLDERS.

The RESTORE POINTS may be infected with the Malware and cannot be used. Delete the old one(s) and make a new one.

CLEAR OLD RESTORE POINT(S). HERE'S HOW:

1. Click Start, and then click Control Panel.

2. Click Performance and Maintenance, click System, and then click on the System Restore tab.

3. Select the Turn Off System Restore check box, click Apply, then restart your computer.

4. Return to the System Restore Tab and turn System Restore back on.


TO SET A NEW RESTORE POINT:

1. Click the Start button.

2. Point to Programs, then navigate to Accessories, then System Tools, then click System Restore.

3. Choose Create a restore point, and then click Next.

4. In the Restore point description box, type a name for your restore point, and then click Next.

5. Click OK.

NOTE: If you are using Windows XP Service Pack 2 (SP2) and are unable to access the Internet after removing Malware, there is a command that may fix the problem. It works by resetting the winsock catalogue. Click on Start, then Run and type CMD in the box. Click OK. Type "netsh winsock reset" (no quotes)into the DOS window that appears.

At times Mcafee and Norton come out with customized removal tools for certain apps...difficulty in removal stems from the Trojan using a system file, usually so it can't be deleted thus the option..
suggested technique:
Start->Run...enter msconfig.exe and press enter..
In the resultant application select Diagnostic Startup and ok it..
then reboot the system and ..when it reboots select to run MSCONFIG again from the startup alert after logging in...
select "Normal Start-up" only this time "EXIT WITHOUT RESTART"
now run norton or the customized app for this trojan's removal and see..

additionally when you restart the pc after running norton and removing the files ..IF the warning comes again.
reboot and press F8 button immediately after the Motherboards boot up screen or rather just keep pressing it while booting till you get a Startup sleection screen...select Safe Mode and startp the machine..then run Norton or the customized app for the trojan again in this setting and try removal...

all else failing...save your settings using the desktop settings transfer wizard on a logical partition(non-system partition) and then re-install windows and reload all norotn applications and scan ur system before installing other apps soas to ensure that it is clean from the get-go..

All Trojan horses are hidden files, in order to get at them you will need to go to Start /Control Panel /Folder Options (click the View tab)and uncheck both the *Hide file extension for known file types & *Hide protected operating system files (Recommended)-boxes, then OK yourself out. Then you will need to restart your computer and go into SafeMode by HOLDING the F8 key DOWN -(at bootup - after the first screen info - be quick!) and choose SafeMode. [You have to use your keyboard when you're in SafeMode - the keys to use are Ctrl/Alt/Delete (to exit the Help and Support screen) - Tab/Arrow keys/ Pageup/Pagedown/ the Window key(between Ctrl & Alt) & Enter] So, from the DeskTop screen press the Window key to get Start/ arrow up to Search/ arrow right to For Files or Folders and type up the NAME OF THE FILE & EXT (not for example horse.winshow.V) but the actual name of the file, which would have shown up on your anti-virus software. To delete this file from here just press Page Up to highlight the file and then delete. To get out of Search -Alt F/ arrow down to Close and press Enter. Press the Window key to shutdown and restart your computer.

It will be safe to empty your Recycle Bin in the Normal mode where you can use your mouse.

I have had 4 trojan horses on my C drive and kinda figured out the above method a week ago. After unchecking the hidden files boxes I deleted the Temp file from the _Restore folder (as these keep putting the same files back into your system), then went to SafeMode to delete what virus files that were still there. My computer is now absolutely FREE of these pests!

hope this helps...Phyl

Wipe the hard drive an a new install.

Get all of your CD together.

Shut down system. Disconnect internet cable from computer. Load WIN XP disk

Answer 6

Go to "www.pandasoftware.com". They have a free virus scan that you can run. It will also get rid of all threats that it finds. All for free. I use it all the time. It's great. It may take an hour or two depending on how big your hard drive is, so just give it time.

Answer 7

All you have to do is download spybot search and destroy its free and adaware its free run them, trogen gone, keep them updated and run them once a week or when you think you have a problem. Plus spybot will automatickly protect you from trogens, almost all of them.

Answer 8

Nevr flush a Trojan down the toilet. Could clog up. Just kidding!

Take your putor to the shop.

Answer 9

Ah yes, another poor victim for Norton's onslaught of crappy protection. You have "Adware".

Download "AVG Free" , "Adaware SE" and "Spybot - Search and Destroy" (Google them.)

But before you install AVG uninstall norton (trust me you are much safer without it)

Answer 10

You need an antitrojan program.
