It may be just hiding.   You could create a new shortcut in programs files... Or you may need to go to the c/drive windows and make a new shortcut.\nE

First use the antivirus and antispyware software you have to run a full system scan. Do it in the windows safe mode. (AVG and avast antivirus softwares are free while a 6 month free trial for Norton is available at pack.google.com. Lavasoft's free Ad-Aware is the best antispyware to my knowledge. Also Windows Defender from Microsoft is good enough for real-time protection). This should identify the problem and most probably would solve it as well. However, if the antivirus software is unable to delete the malware, go to Norton's website and search for the name of the malware detected. Their must be some instructions posted to tackle the problem. You might have to delete the system restore points and as well delete the particular registry entries manually if the virus still regenerates on subsequent boot up of the machine. Good Luck.\n\nPS. If you are still having trouble, use Hijack This and copy the log it generates and post it on some tech help forum. I am sure there will be plenty of people ready to help you out.\n\n_____________________________________________________\n\nAnd please after excorsizing your lost pc, do give Firefox internet browser a try. It is free, more secure, highly customizable (using extensions) and a better overall internet experience.

Here's what i did...\nIf you remember the time when your system got infected with them, you could go for a system restore  for that date. It's like the undo command in MS word....only this time it's for your system. \n\nHowever, watch out!!! Anything that you installed in between that date and now, would be deleted! Be it software or any other thing, it'll just go away.\n\nI remembered my infection date to be just the day before....ran system restore and my PC got a clean bill of health. \nAbout Anti-Spywares and anti-Adwares that the others are saying,  you can never be sure as to which one is really effective. Some of the most famous ones are,of course, but remember one can never be sure.\n\nOh yes!! just remembered something. When my PC got infected with Spywares, it suppressed all installations of any Spyware and Adawares... That prompted me to go for system restore... Thanks to some wonderful users of Answers for helping me at that time!\n\nTo access system Restore, just go to Help and Support...\nClick on "undo changes in your computer with SYSTEM RESTORE"...\nClick on the date that your PC got affected. and just follow the process from there...\n\nIn case you don't remember the date, i suggest you to go for some real top-notch class Anti-Spywares and Anti-Adwares.\n\nGood Luck and tell me how it goes!

There is a yellow symbol in your tray that looks like a badge and that symbol is part of Microsoft platform.  It will show in the tray as yellow when there is a critical update if you have auto updates checked off for Microsoft.  It will turn red if you have turned off any of your security. \n\nIf you are talking about a different box saying "Windows Installer", you have a virus in your system.  \n\nHope that you use an antivirus program.  If so run the program and see if it will go away.  If not "restore your system".\n\nIf you have no antivirus at all, you can download an excellent free antivirus program from http://www.avast.com  They are out of Prague.  And they have an excellent background scanner that really works and would catch any virus embedded in a webpage in real time and destroy it before the virus can enter your system.  Plus you get auto updates two or three times per day. \n\nThis program for sure will remove the virus you have described.\n\nJust remember that you can only run one antivirus program, or you wil have serious conflict with your system.  You can run three or four antispyware programs without any conflict. \n\nI use this progam an never had one virus in over nine years. \n\nSome one suggested you use SpyBot Search & Destroy.  The owner is a personal friend out of Germany.  Friend or no friend I would not use this antispyware program.  Not because he and his students in their University designed the program, because it finds nothing but a few cookies and always "NOS".   Plus the scanner likes to freeze up on you.     \n\nClinical Psychiatrist, France.

Start menu > run > type in : msconfig.\nIn the new dialog box that will appear, choose the start up tab where you will find a list of all the programs that run on you start up. Uncheck whatever you like. I suggest that you leave your antivirus checked.

well, Im no expert but you could have provided more detail. Like when did this start to happen? Have you installed anything lately? There might have been a conflict with some other software or you might have intentionally deleted some files that it needs to run. I suggest that you either go for system restore or if that doesnt do that trick uninstall then reinstall...Hope that helps. (",)

Nothing to worry, dont panic. Use system restore. Go to start, programs, accessories, system toos and system restore. Try to uninstall the program which u installed last. Did u do any upgradation.

Depending on your Antivirus...Almost every good one with have special removal tools for the stubborn ones..like Kaspersky, Norton, McAfee, etc...go to the site that makes your antivirus for the removal tool...remember to disable your Systems Restore before rebooting after removal or it will be put right back on your computer the next reboot...they tend to store themselves there...

I used to have such problem. I  carryout system restore...!I suggest that you  try to carryout system restore to a day previous to the day when there was no virus. The problem is likely to be solved. Then,You insatll a standard antivirus soft ware such as Norton, AVG , Avast ( free antivirus software  and Ad-aware, Ewido ( free spyware removers). You can download free softwares at\nhttp://fixit.in/antivirus.html and http://fixit.in/spywareremover.html

1. Go to the virus scanner manufacturer's website and look for customer support.\n2. If your computer is that screwed up, I would wipe it clean and reinstall the operating system (after saving the important files on disk).
