How much the performance can be increased by SLOW-PCfighter varies from computer to computer (depending on what is causing it to be slow).

Please start by doing this:
* Do 3 scans and repairs directly after each other without restarting your computer.
* After the 3rd repair restart your computer.

If the computer is still very slow it could be caused by these factors:

1) You have a lot of anti-virus programs
You should never have more than 1 anti-virus program installed at any time. The reason for this is that they can start "fighting" with eachother and this can result in your computer exhibiting unexpected and undesirable behaviour.

* Uninstall all anti-virus program except one.

2) You have a lot of security programs
Having a lot of security programs can take up a lot of resources because every program wants to scan when a file is accessed.

* Uninstall all security programs except 1 anti-virus, 1 anti-spyware and 1 firewall product.

3) You have a lot of small programs running in the background
Many programs want to run in the background just in case a file/program they are associated with should be opened. This saves a split second when opening that particular file/program, but will slow down your computer's startup process as well as taking power from your computer because the programs are running in the background all the time.

* Uninstall all those small programs that you are not really using.
* Deactivate the programs running in the background which you are not really using that often (preferably stop them from starting up all together - they will normally continue to start up when an associated file/program is opened).
* As a last resort you can deactivate programs, so they do not start when the computer is turned on, through SLOW-PCfighter. To do this simply un-check the box next to the program process in the Utilities menu (Startup Manager in the US version). Note: You should not uncheck the processes which are related to important programs such as security software.

4) Your harddisk is full/fragmented
If you have almost no room left on your harddisk and/or if your harddisk is very cluttered then it can take a long time for programs to start up. This can be solved by running a disk defragmentation.

* Delete as much from your harddisk that you do not need.
* Delete Temporary Internet Files; open an Internet page, go to Tools -> Internet Options and click Delete under Browsing History.
* Run a Disk Defragmentation; go to Start -> All Programs -> Accessories -> System Tools -> Disk Defragmenter.

5) Old computer
If your computer is some 4-5 years old (or even older), and you have already done what is described in the 2 previous points without it getting better, then we can not help you further. Because then, the slowness of your computer, is caused by the programs running on it taking almost all the power out of it. This is unfortunately a normal development as programs gets more and more demanding to be able to offer more and more advanced features. Especially anti-virus programs will be "sinners" in this context as the checks that accessed files needs to go through gets more and more extensive. So the problem is caused by the hardware (the physical components) not being able to meet the increased demands from the software (the installed programs). This will naturally be felt more on an older computer because its speed does not grow as time goes by.

* Upgrade your computer hardware or buy a new and faster computer.
