Everything seems to be going wrong!!!

Hope someone can help me on this one. I tried blueyonder help but after nearly an hour on the phone they couldn't help me. I downloaded PC Guard from the blueyonder website about a month ago which was to replace a Control Kids programme I was using (I still can't get rid of this for some reason) everything was going o.k. until somehow it started to uninstall - I panicked and pressed cancel (moment of madness!!) it then said that my antivirus was not working nor my anti spyware. decided to uninstall completely with the intention of re-installing. All was going o.k. but right at the end of installation it said that my antivirus and antispyware could not be installed and I was to contact blueyonder - which I did but as I said they were no help. Some of the websites they asked me to go on were blocked by my Control Kids software (even tho I have uninstalled this) In the meantime as I am worried I have no virus protection I have downloaded the AVG software which has picked up a virus on my system. Everytime I switch on now it says 'c/windows/dvpd.dLL contains a signature of the backdoor program BDS/Dumador.DD.2 Backdoor server programs' - it then asks me what to do and I click on delete put it still pops up everytime I switch my pc on. It also comes up with 'winldra.exe error message which I just cancel - then a 'windows installer message comes up and after about 5 mins it says 'antivirus could not be started' then windows installer comes up again and after another 5 mins it says 'anti-spyware could not be started' ..... so I am unsure whether my PC is protected or not.

I should add that I am unfortunately not that technically mind so any help in layman's terms would be really appreciated.

Thanks

You got some serious issues that require more than what free software can solve for you.
Download the trail,fully functional, versions of Nod32 and Ewido Security Suite. Do not install these 2 programs until you uninstall the AVG anti virus program.

Turn off system restore in XP to clear all your restore points. You don't want to reinfect your computer by using a previous restore point. Also the 2 aforementioned programs will find any nasties in your restore points and that would just add to the confusion.
After rebooting your computer when you have uninstalled AVG go ahead and install Nod32 and Ewido. Update both programs before using. Run Nod32 first and let it clean/quarantine anything it finds. Then run Ewido and let it clean/quarantine what it finds. Remeber to update both programs before using.
Then post a HiJackThis log in the apporiate forum on DAL for a look over by the experts to advise you on any other problems. Here's the link to HiJackThis. Unzip HiJackThis to it's own folder.

Hi there, thanks for your reply. My system won't let me go on the www.ewido site as it is coming up with 'Restricted Site' this is down to the Control Kids program I had but deleted - it is still somewhere in my system tho (I found it in the System32 folder - but it won't let me delete it) I have managed to download the Nod32 program and it is currently scanning my computer. I have tried to uninstall the PC Guard also but it comes up with 'unable to uninstall antivirus and antispyware - so I am unsure what is going on or what to do next. when the Nod32 scan is finished to I post that log?
