I found a couple of keyloggers on my pc yesterday (accidentally "installed" by my daughter -oops). Apparently the pc shut down & restarted whilst she was browsing!
Problem is, I used bank card details on Tesco Direct last night whilst these trojans were on my pc.
Question: Can keyloggers etc work whilst I am inputting details on a secure site paying for goods? - or does the padlock logo shown on screen on these secure sites offer me security protection & encryption & inhibit the keylogging capture?

Keyloggers work regardless of what you're doing, encrypted websites or not.
#2
why would ur daughter install keylogger? or more to the point how did she come to download them lol but to answer ur question, yes they log the keys the person types on ur keyboard, hence the name key logger

SSL (the padlock) only secures the transfer of data between your computer and the website, so if there was a keylogger on your system it could very well have recorded your keypresses unfortunately.

Might be worth getting in touch with the bank and advising them, they can then at least look out for any dodgy transactions and might even issue you a new card.

meanwhile, make sure you have a firewall installed and some decent anti-virus software!

If you're paranoid in future use a virtual keyboard, Start->Run type in "osk" and hit Enter.

think she clicked a pop-up and it auto installed; I found progs like snapsnet & wavvsnet & prun.exe after scanning - hopefuuly PC Cillin has sorted it - it found about 10 or so trojans

I am guesing that she clicked to install by mistake which allowed the install , I did have NOD32 running

yup, no amount of anti-virus or firewall will protect from user error :)

Probably nothing to worry about in terms of your card details, but better to be safe than sorry!

I would change any/all passwords you have aswell, just to be a bit safer.

If you are using Windows XP or Vista it is VERY easy to set up a userid for each person who uses the computer.

Go into the Windows Control Panel and select User Accounts.

Set up one for your daughter, give her LIMITED capability (which stops her installing programs).

Then add a password to YOUR userid so she cannot use it (and remember your password)

When you start Windows you will be offered the chance to logon as YOU or HER (or any other IDs you set up).

That means YOUR desktop and HER desktop are totally separate and whatever SHE does will not affect YOUR desktop and vice versa (and she cant install any dodgy programs).

She (and you) can have your own background picture, your own favorites etc.

If at a later date she gets problems with her ID you can go into User Accounts and delete it, and then create another "fresh" one for her.

This is not guaranteed to defeat keyloggers since osk generates a keyboard event message that the keylogger intercepts. For more information look up Keystroke logging
in Wikipedia

True but at least it does defeat physical key loggers, wired or wireless (not all keyboards encrypt wireless communication, old Logitech models used with Vista for example).

Key logger stores information on a database, so whatever you type it get noted down, so all passwords and bank details etc....

These can get into your computer malware or viruses and can go undetected. So make sure a firewall is active all the time and scan computer now and then!! :thumbsup:

If you are usng XP then the Windows firewall is not good.

The one in Vista is better, but still not as good as a product like zone Alarm which provide a free version for home use.

http://www.zonealarm.com/store/content/catalog/products/zonealarm_free_firewall_b.jsp

The reason the firewall in XP is not good is that while it checks programs that are coming IN to you computer, it does not check programs going OUT from your computer.

Keyloggers work by sending details of what you typed OUT to other computers. If you have the XP version of the firewall then it is NOT checking for this and the keylogger can send its information home without being monitored.

Keyloggers can also get installed by anyone who has physical access to your computer.

So a husband / wife / boyfriend / girlfriend could install a keylogger to check what their partner is up to if they suspect they are having an affair. It will monitor what is typed in emails and instant messaging programs.

A keylogger could also be installed by a "friend" for a joke or other devious reason.

thanks for the advie guys, i tried zone alarm some time ago and it drove me nuts, abit like spybot really, it asks you to allow or deny but most of the time i dont even know what its asking to do

J9STL if your concerened14 that you may still have something on your machine or just want peace of mind, grab a copy of HiJackThis and use it to create a log file. Past the log file and a description of your problem at [url]www.techmonkeys.co.uk[/url] and I will get one of my spyware specialists to take a look

When it asks you to allow or deny just press the option which says "dont ask me again" or words to that effect and it wont ask you if the same program tries to acess the internet again.

One way to see if there is any rogue program trying to get in out from the internet is to turn your PC on but DONT USE IT. Just leave it sitting there for a few hours.

If you get a message from zone Alarm saying a program wants to access the internet it MAY be a rogue program.

Note there are some programs like anti virus or other programs that try to access the internet now and again to see if there are updates or new versions to install. These are obviously OK to let through.

If there is a program trying to access the internet and you dont know what it is then write down the detals and either search the internet to see what it is, or ask on here or some other forum.
