I have been running W7 Ultimate 32 bit for a couple of years now with no problems. PC is a bit old now, P4/3ghz with 4gb ram (that's the max!) but recently it has started to lag, the hard disc is churning away and task manager fluctuates between 50% and 100% cpu usage. I haven't installed anything in a while and I've run jv16 powertools which removes obselete files/registry entries etc. so I don't know what's wrong. I have a fibre connection averaging 30mbit.

Any ideas?

Thanks.

Registry cleaners CAUSE problems, they don't cure them.

Which process is spiking in task manager?

Have you run full scans with BOTH your anti virus app and MalwareBytes?

Well, I have confidence in jv16, I've used it for 5+ years, it clears out redundant reg entries. I know it's not a fix for all but it's a useful tool, gets rid of a lot of junk. Svchost appears multiple times but I don't how know to read what processes it accesses.

I'm very familiar with JV16 and I assure you that at best it is useless. As is the case with all registry cleaners, the best of them do nothing harmful (or useful). The worst of them can leave your system useless. But it's your system, do as you wish.

You didn't answer my last question. Have you run full scans with both your AV AND with MalwareBytes? If not, please do so.

By the way, here is BC's stance on Registry Cleaners:


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.

Hi, you can do a system restore, and restore it to the time your pc was fine. go to start- search system restore. Then find a restore point then it will restart your computer. If this doesnt work then you need to dwonload malwarebytes and do a full complete scan or with your antivirus.
