My laptop is running slow and has some application that downloaded itself and I can't get to uninstall the programs and can't defrag

Open file explorer.
Right click on any folder.
Click on the "Tools" Folder.
There you will find a button for running the defrag program.
It will defrag the whole drive.
Remove surplus programs by going into the control panel and pick programs and features. Click on a surplus program and it will give you the option to uninstall it.

' Disinfect your system using some reliable antivirus program.
' Run disk clean up (start > programs > accessories > system tools > disk cleanup.)
' Disable background services.
' Fix OS registry errors with any reliable program (must use RegInOut for it.)
' Defragment the registry if needed.
' Uninstall all programs & software's and download latest versions of them.

Thanks

Computers over time will slow down this can be caused by just normal everyday use or an infection by a virus.
First thing I would do is a basic cleanup of the computer by running the following applications on a regular basis.
First CClenaer https://www.piriform.com/ccleaner, this will clean up all garbage files left behind.
Then you need to run a defrag program, you can use the built in Windows defrag program but I recommend Smart Defrag, http://www.iobit.com/iobitsmartdefrag.html. these both are free applications.
If it is a virus then I recommend that you run your anti-virus with the latest updates, if that does not work you will need to create a bootable disk with an anti-virus application. You can Google this or contact a local PC repair shop.

You may have to many startup programs that will slow it down, go to www.download.com Type ccleaner and include smart defrag, these two programs should give better performance and speed. When that is completed uninstall programs not been used, this will aid in getting it to shut down.

try changing your CMOS battery

Hiya what processor do you have in... its what & how your processor uses the ram available that would normally determine a happy environment. the minimum ram that Vista is happy and stable running on is 1gb.. so 1gb left over should in theory be enough to run all your office applications... what Version of Office are u running?

Have you recently installed an application that may be in conflict with vista?
Have you tried doing a virus and spyware scan? I would by process of elimination uninstall and reinstall programs to determine what... if any are causing any potential problems.
Do you defrag when necessary?

Try these first .. and we.ll go from there if necessary!
