I am running Windows XP SP2 and downloaded Microsoft Silverlight. I have attempted to remove it through Add/Remove Programs, but I receive the message "Cannot open, verify program is installed." I have deleted the program from my C drive. Automatic update keeps attempting to download to Silverlight every time I shut down.
Microsoft Silverlight is similar to Adobe's Flash. It's required to run certain Web content. You should go to www.microsoft.com/getsilverlight and have it verify your PCs current status regarding the Silverlight install, and let it install the latest version. I would recommend keeping it installed, but if you really want it gone, try removing it after this fresh install by clicking the "Uninstall Silverlight" link on that same page.
I have a Dell computer running Microsoft Vista. There are programs in the registry that I no longer use and thought they were off my computer, like MacAfee installer. What registry cleaner free download do you recommend? Also, I downloaded Microsoft Security Essentials. You have given instructions on how to delete Windows Defender, however, it will not allow me to delete it.
I don't recommend any registry cleaners. Are they all bad? Probably not, but if things appear to be running fine, why risk new problems by letting some program run through your registry? Those extra entries are not going to make any difference if removed. Regarding Windows Defender, Security Essentials has its own built-in Windows Defender, and it disables the older Windows Defender upon installation. You may be trying to delete the wrong one. You need to uninstall Windows Defender, not delete it. Go to Control Panel, Add/Remove Programs to officially uninstall it.
I am using Microsoft Security Essentials. Today, I went to www.malwarebytes.org. After clicking on free scan, they showed that I had 198 registry errors. I don't seem to have any problems with my system, but 198 errors frightened me and I decided to defrag. Should that have solved my problems (all 198 of them)?
Defrag just pieces together fragmented files so they can be accessed a little faster. It has nothing to do with whatever error/warning messages you saw. Every time I mention www.malwarebytes.org, I try to specify exactly what it is you're going after. It sounds as if you clicked and ran something other than the free Anti-Malware program. Here are the instructions again: Go to www.malwarebytes.org. Click the giant "Download Free Version" button. Here's where it gets tricky. Malwarebytes software downloads are hosted by other third-party websites. Currently it is MajorGeeks.com, but it could be others in the future. Those third-party sites are going to try to sell you something; you don't want it. You need to look for the Download Locations link. Click one of those links and the download should start. The file you will be downloading is MBAM-SETUP.EXE. If you see anything else, it is not the Anti-Malware program. Whatever it was that you downloaded which showed "198 registry errors," uninstall it and get it off your system.
