Hi all I have just finished getting rid of an "Invader" virus from my Dell laptop, running Windows XP Home Edition. On the laptop, i had PCShield Security, which failed and i cannot fix. So, i uninstalled PCShield and installed the Trial version of McAfee Security Center. After that, i couldn't open Internet Explorer 6. I Uninstalled McAfee and i could open and use IE6. However, i have now reinstalled and running McAfee (as i need/want the protection) and i cannot open Internet Explorer 6 or open MSN Messenger. When i try to do so, it tells me that it has "encountered a problem and needs to close". Is there a compatibility issue? And is there anyway i can resolve it? Thanks for any help.
Type in the Command Prompt interface sfc /scannow (with the space) and let it run. It may or may not ask you for the system CD at some stage, do so if asked. That will check the system files for integrity.
If you don't have the system CD can you tell us how the system is installed, from a backup partition or what?
When this is all sorted out you need urgently to update to IE7 as it is safer and more reliable.
