essy87, Thank you for using the Dell Community Forum. Removing the infected files and malware does not always repair the damage that was done. You can attempt to do a factory restore if your system has this option by pressing the F8 KEY when booting up and choosing "Repair Your Computer" This will also remove any information you have installed on the system. If the system does not have the restore option you can also try pressing the F12 KEY while booting and choosing "Last Known Good Configuration". If all these fali to resolve your issue you will need to format and reinstall Windows.  
Hello,   There are a couple of things wrong with my laptop at the moment. I don't think they're related, but perhaps an expert will disagree, so I'm posting both here. I'm running Vista Home Premium, no cracked software.     Thanks in advance!
