In order to edit the registry, you need to know just what changes it is that you are trying to reverse. Unless you know where the nasty has been, then you have no way of knowing what its done. Often it can be as simple as a single number in a string of numbers has been changed from 0 to 1, or vice versa, so its not really something that can be fixed without very specific information.Fighting nastie's is one of the hazards of using Windows. Your security software is supposed to be a defense against these things, but its a just another tool, and no security software is 100% effective.Another advisable thing to do is regularly set restore points. When you think your computer is running well, and you are happy.. set a restore point.. name it with something like 'current best' so you can find the right one, and when you have problems, restore to there.If you ever do try to make changes to the registry, be sure to set a restore point first !!!!To set a restore point, go to start>all programs>accessories>system tools>system restore and choose your options.System restore will remove any software you have installed since that restore point was set, and reverse any changes that software had made, and it backs up the registry as well. It will not remove data which you have collected since then, such as music, email, photos or documents.System Restore is a good tool which isnt used enough in my opinion.It's not total protection.. nasties can infect the System Restore data too.. but it's effective most of the time. Of course, it will also wipe out older restore points as it runs out of room to store new ones, so its a good idea to set a new system restore point regularly. Even a complete backup of your registry has both good and bad points. A registry backup will certainly restore your registry, but if you should wait too long between backups, then every change you have made in the interim will be undone. This means much of the software you installed since you made the backup will cease to function, or not work properly. On the plus side, if you use a separate registry backup tool rather than relying solely on system restore, you'll get a separate file containing your backup, which you can store wherever you like. This means that the nasties wont get to it, as many nasties will infect the system restore volumes as well. There are many free tools for making registry backups in this fashion.. one you may wish to try can be found here.. http://mztweak.bravehost.com/MzRegBackup.htmlAlso, a limitation which applies to System Restore in Windows versions prior to Windows Vista is that only certain file types and files in certain locations on the volume are monitored, therefore unwanted software installations and especially in-place software upgrades may be incompletely reverted by System Restore. Its better than nothing, though, and another good tool in the fight against evil!
