if you're trying to get rid of a virus you're better off using antivirus to figure out if you have a virus and which one it is first, then work on getting rid of it

Think a virus problem.. else there's something wrong in your Xp so first get Scan Completely if still not Fixed... try Restoring your computer accessories > system tools > system restore > and do it...\nif you have installed some useful programs and don't want them get uninstalled then don't restore..... instead Get registry Mecanic becasue there must be problem in you registry..... http://www.download.com\n\nif you know registry editing then you can got to run > regedit> and see.. if any changes...  possible

As for the virus ...even if you already have a virus checker it may not be up to date. Best one I have found is...\ngo to www.download.com and download a free antivirus program called AVAST.\n\nThen uninstall windows explorer and reinstall with your windows cd..if your running win xp you won't need your win cd\n\nGood Luck

Hi,\nIt could just be a virus or something that affects the programs.\n\nI have a problem like that but I still haven't found a solution!\nTry to pop it into your local PC store and see if they'll try to repair it or they will give you guidance on what to do.\n\nHope this helps!

it actually isn't a virus, and system restore can't be performed (he can't get any desktop or start button icons), explorer.exe is failing to load into memory. my guesses are that a service upon startup is failing to start.\nwhat i'd suggest is to start windows in safe mode, and go to event viewer and check for system errors.\ni know how frustrating that could be. ;o)

the Active X program is safe, by it self, but a lot of vires and trogrens then to run useing this progrem, dowload it, just make sure that you have an anti vires.

Sounds virussy. Are you able to boot up in safe mode to run a virus check? \n\n(Hit F8 repeatedly during the boot to get the boot menu, and choose safe mode)

I believe you have WinXP-SP2 Pro as O S. First you may unistall using Add/ Remove programs in Control Panel. You may succeed now as you start afresh after going thru the readme.txt that takes care of all your doubts/difficulties.

Start Menu/Control Panel/Add and Remove Programs would be where I would start.  Maybe get a virus scanner McAfee works quite well.  and get the updates.

I run all the same programs. First log onto Windows up date and make sure you have ALL of the available updates for XP(especially the security ones,you may be surprised if there are a lot).You may have to disable Adware to do this. Then make sure you are running Nortons fire wall and not the Windows default firewall(this is usually done automatically upon Norton set-up). Make sure you run live update on Norton Program every day that you log on to the internet. Do not trust Any Auto up-date programs! Run A full virus scan manually now and no less than once per week. Then see about reloading your set-up program. If this does not work, Try resetting your computer to the very first day you installed XP and repeat the above procedures. Somewhere, something in your setup program has been removed. If you continue to have this problem, E-mail Microsoft's Help Desk. GOOD LUCK!

Well, you have a Windows problem. Start it in Safe Mode. Go to control panel -> add/remove programs, and look to see if there are any programs that you don't recall adding. A good indicator is something like Bargain Buddy, Bonzai Buddy, Kazaa, etc. Remove those from the add/remove programs section, then run your virus scan. (You do have an updated virus program, right?). Then attempt to restart. \nGood Luck

each virus is different, so you'd need to know which one it was...or know in-depth how your os works (and that is a book, not a post at yahoo answers)

Try those programs>\nWindows Defender from Microsoft.com (for XP only)\nSpyBot S&D\nAvast! Pro\nand/or ZoneAlarm

See if you can reset the internet settings.\n\nHit Start-Settings-Control Panel-Internet Options\n\nGo to the "Programs" tab and hit "Reset Web Settings"\n\nIf this doesn't work, or you don't have that option, you may want to look into a virus scanner or spyware scanner.\n\nIf nothing works and you absolutely need it working, you can always re-install XP over itself. As long as you don't re-partition or format, you shouldn't lose anything.
