Oh wow... Thanks so much!! All seems to work perfectly now!

conormacklin, you need to run another HiJackThis scan just to be sure and post the log here. There were a couple other fixes that needed doing that I saw when looking at your last HJT log but wanted you to run that Malwarebytes' program first.
Judy

ok, here's the new log.

I see you still have that Modem On Hold program running at start up and all the time in the background. Program is located in C:\Program Files\NetWaiting\netWaiting.exe

If you don't use dial up then you don't need this program. There is no reason at all for it to be starting or running. Disable it

The other thing is your java is out of date so you should update that.
Go HERE and download the Offline Install to the desktop. Once you have done that then go to Add/Remove and Uninstall all old versions of Java you find there.
Then double click the Java Install icon on the desktop to install the newest version. Once you have done that then go back to the Java download page and on the right side you will see Verify Now. Click that to verify the installation was successful.
Other than those two things I would say you are good to go!
Judy

Ok thanks, done all that!
By the way, do you know how to stop programs running on startup? For example my orange wireless conector program thing I don't really need it. And there is some pogram that tries to run every time I turn on the computer called "SNlIKnwcXNF.exe" which I don't have a clue what is, it says it is RealTek HD audio control panel =/

Type msconfig in the run dialog box and go to the startup tab. here you can check and uncheck startup programs

Ok done! thanks!

This start up process is unknown, have searched and found no information about it. Disabling the start up is really not enough this will stop it from starting but does NOT remove it from the computer, we need to find out what this is and possibly take steps to remove it. It could be a dangerous file so please do the following:

Go to http://virusscan.jotti.org/
Upload the following file

C:\Documents and Settings\Claire Macklin\SNlIKnwcXNF.exe
It will then be scanned by multiple virus scanners and you will receive a report about this file.
Please post back with that full report.

Judy

ok, il do that afterr eating, and the other thing is, it keeps changing its name.
