how can I repair damaged registry files?

Question

I had a virus. Now my browser window freaks out when I type a lowercase L and typing o acts as an override command.

Answer 1

I would suggest reinstalling Windows. That doesn't mean foratting your hard drive, though! You can reinstall Windows and it will keep all of your files, but it will also reinstall your registry, which should fix any registry issues.

After that, you can buy a registry cleaner to keep your registry optimized and for better performance of your computer. I suggest Registry Mechanic. It's about $30 online. It will give you a free trial, but won't fix everything.

Hope this helps!

Typically only your profile is affected. User profiles reside in c:\documents and settings. Each profile folder is named after your username or logon name. If your computer logs on automatically it is still using a username. The partricular Registry hive that adware and malware attack is the HKEY_CURRENT_USER hive. This hive is store in a file called ntuser.dat. Every user profile has an ntuser.dat file. Delete this file and you will not be able to logon as that user.

Try these steps to create a new user account and build a new profile to see if the problems are truely related to just your user profile.

1. click on Start | Run
2. Type cmd.exe (press enter)
3. in the black window

type net user test comp1234pc /add
type net localgroup administrators /add

Logoff and than back on as test with password comp123pc

See if the problems are resolved. If they are you can follow steps 1-3 again to create a username and password you want to use. You'll have to copy your Desktop, Documents, Start Menu and Favorites folder over to the new profile. Do not copy anything else over since viruses and malware tend to hide files in you temp and temporary Internet files folders.

Well good luck.... Sometimes you can search for .exe files by date and find ones recently added to you computer. These try to assume a Windows name that any end user would believe, but they are not actually Windows related files. You really need to know the Windows OS when doing this.

You need to be very careful doing anything with the registry. The best thing would be to use "System Restore" to go back to an earlier version of your system before the virus; you can find it under Accessories -> System Tools. I you have any type of back-up of your registry or system files, that would work, too. You might also check the Web to see what type of typical damage your virus typically causes. The only Registry cleaner I would recommend would be CCleaner, but I don't know if that would work in your case. Good luck.

Any application that's used to 'repair' registry entries is continuously prone to harm a laptop - that is why many laptop discussion board whizzkids will say to not use such application with none measure of warning. What makes the possibility of harm to a laptop much more likely through the usage of registry application is that a few systems are not able to manage sixty four bit registry entries, and if you are utilising a 32 bit registry cleanser, it is most likely that it is going to decide upon up sixty four bit registry entries as junk. Delete the ones on a sixty four bit process with out checking the 'precise' compatibility of a application with the platform it was once designed for use on, you'll simplest anticipate disorders. There isn't any trustworthy solution to manage registry entries and with the myriad of registry cleaners already to be had, typically it is a lot bigger to move trawling the online for assets of safe expertise approximately what's trustworthy to edit or cast off within the registry than to go away it to a application. Tuneup Utilities, CCleaner, Glary Utilites, Uniblue, and so forth and so forth and so forth and so forth. There are stacks of systems that paintings on a process's registry, however none of them are one hundred% trustworthy to make use of - no longer considering the fact that of viruses in line with se, however with ease considering the fact that they would continuously have you ever cast off one incorrect access and that is the only access that'll reduce to rubble your process. As with any hardware add-ons, and as already acknowledged in a prior reply, you probably have a trouble with an unresponsive element, motive force (re)set up most of the time works. Backing up the registry earlier than any alterations are made to it's continuously, continuously, continuously, continuously (routine) major. So many folks fail to try this, and such a lot of folks become having extra disorders considering the fact that they do not again up the registry earlier than they do have alterations made to it. If not anything looks to be incorrect together with your process, in a few circumstances it is satisfactory to go away it good on my own. If it ain't broke, do not repair it. If it's broke, gradual and constant wins the race. The trouble with registry cleansing/solving application is that it does not simply manage one access at a time (it might be form of needless to have it or else), it alterations and even gets rid of something as much as a substantially gigantic quantity of registry entries at anybody time - to that finish, despite the fact that it can be painstaking, I do not endorse the usage of registry cleansing application until it sort of feels to be 'definitely' major, and might quicker hunt by way of boards for ideas and recommendation earlier than having alterations made to the registry.
