I've been having a look at my Daughters computer as it's running extremely slow. I've run various spyware, malware etc stuff on it & cleared all i found, which wasn't very much. As it's only around 3yrs old (running XP) & not cheap at the time, i don't really know what else to try. I've also stopped as much as i can from starting up.....
My question is,... Other than re-installing the PC back to how she first had it, would using a Registry cleaner (Regcure) be worthwhile? Doesn't re-installing do more or less the same thing, with just needing to update software afterwards?
I have re-installed it before, but can't say it improved much at all.

Any thoughts/suggestions?

Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons:

• Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.

• Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.

• Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.

• Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.

• The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.

As I've said many times, registry cleaners, tune-up programs, and so-called "optimizers" are the current snake-oil of the internet. There are countless free programs like this and apparently some paid ones, as well.

Do not be deceived. They promise performance you can only dream about....but only deliver a computer that is worse off than it was to begin with.

What all was found by the malware scans? It may still be infected...

Using registry cleaning softwares doesn't so popular here, big guys don't recommend it because registry stores higly important files of windows so it is good to leave it untouched.

From what you sayin' you use it for 3 years, have you ever sent it to service in this period or any technician seen it? if not may be it is a hardware problem or there are huge amount of dust collected inside of it. Because you say you didn't notice great difference even after you format it. So i assume it can't be a malware problem of course it can be "hijacked routers etc.." but my first thought is that it can be a hardware problem.

While not a reg cleaner, windows cleanup can be useful at speeding up a system that has been running for sometime. It is part of xp.

Read the support info

Also new versions of spybot offer to remove temporary files even from non running profiles.

<<Doesn't re-installing do more or less the same thing, with just needing to update software afterwards?>>

Not at all :thumbsup:.

A clean reinstall...is a pristine install of the O/S, where all drivers and programs and O/S updates...need to be reinstalled.

A "system recovery/restore/restart" using disks or mechanisms implemented/installed by the manufacturer of the system...is totally different, with the sole intent of returning the system to the same condition it was in when originally purchased.

A "registry cleaner" is a program that...based on the programming by the developers...attempts to determine whether current registry entries on a system are proper. Among the actions such programs routinely take...the removal of registry entries which the developer felt were "unnecessary". Users of "registry cleaners" don't seem to take into account...that the developer's ideas of what might be "necessary" could be wrong...or outdated...or superseded by updates, files, and registry entries which were not even existent when the "registry cleaner" was developed.

In other words, a registry cleaner is a gamble that whomever developed said program...knows what should be installed/included on each and every system existing, no matter what software/hardware might be installed and no matter what files may have been installed by programs (programs often install what appear to be "duplicates" of files...but they install these files in prlaces where the parameters of the program call for them to be. If someone removes said files from either the file location or the registry...then chances are that the program will not perform as it was intended.

Using a registry cleaner is a gamble, at best...with the system often developing problems for the reasons that I cited.

System manufacturer and model?

How much RAM installed on this system? How much hard drive space?
