    Same problem. LuComServer_3_4.exe runs at startup and continues to run. It consumes approximately 90% of CPU time except when LuCallBackProxy.exe interjects and consumes 90% of CPU time. This issue only started to occur after 31 March 2008. What the hell did Symantec do to my product?

    I've disabled "Turn on protection for Norton products" which apparently has reduced the occurrences of LuCallBackProxy (typically zero) however, the issue regarding LuComServer_3_4 remains.

    Until now I've been ok, but never satisfied with Symantec. Unfortunately, now I'll be switching to another product at renewal time.

My computer is running slow


if it never used to run slow, and now does, then very high chance you have virus. run full virus scans, preferably 'online' , not using your installed antivirus scanner. if this fails to relieve the problem, restart into 'safe mode', and if problem does not persist anymore, it is most likely a driver issue. must uninstall devices from device manager, restart and see if problem is gone. if not, after uninstalling all major things , then use msconfig for 'diagnostic startup', if problem is resolved, figure out which one of the startups is causing it

your System may be slow due to following reason

- Missing Windows updates or outdated drivers
- Not enough hard drive space, too many unused programs
- Left over programs, old cached and temporary files
So Follow these steps to fix computer problem::
- Delete all the temp files
- Remove unused programs
- install latest drivers from the manufacturer site

If you are unable to perform above tasks then use a single utility tool like PC Fresher that will fix windows errors that cause of system slow

How can i make my laptop work faster


Run disk defragmenter located on the system tools menu. You can also disable some startup items that run in the background therefore slowing your system.
To disable startup items:
  1. Use the System Configuration Utility to safely turn off programs that start-up through the Windows Registry. Access this utility by going to the Start -> Runrun.jpg
  2. Type msconfig and press Enter.
  3. Under the Startup tab there is a list of all the programs that start in the Windows Registry. By unchecking many of the programs you can speed up the launch time of Windows.
  4. You may uncheck everything but it is recommended to keep your antivirus checked to keep you protected always.config.jpg

My pc has become very very slow


Hello,
I am amazed though your PC is 3rd level pentium but woirks fine. However today you find something different from your normal use of your PC. Hqave you tried disk clean up or defrag? To do this go to start menu and go to accessories. scroll down to look for defrag to clean up files.
Second, you have perhaps installed files which became very congested to your 40GB HDD and very difficult for a little memory and a processor to move to its normal processing. If you would have an external storage of your files you can do that so that the PC can move fast since during its start up, processor and other hardware can function well.
Last, is to clean up cookies. to do this is to right click internet explorer then choose properties then clean up cookies.
Hope this can help you.

Pc restarts


You have to give your PC time to start-up.. When you first log in to windows, your PC is starting multiple applications that take up memory and processor usage. These programs run in the background after they have been started. So while they are starting and killing your memory and processor, you try and load a game that wants to use all that processor and memory..but it is already getting used by your start-up applications. So your PC is 'overloaded', usually this only makes your PC slow, very slow, for a period of time until those programs are no longer using up resources.

My suggestion... wait a few minutes after you turn it on, before playing a game.... or get more memory and/or a faster processor...

or you could stop some of those app's from running at startup... but giving it a few minutes to 'start-up' is the best solution.

It takes too long to start up


Try deleting your temp files to clear up space as well as run hard drive defragment and disk clean up. This helps most time. If you find that your systems is still running slow, you may need to add more memory to process the data you have on your hard drive.

Good Luck

Internet running slow


your graphics card will not affect the speed of your internet connection, but may affect the rate of video playback from streaming or downloaded video. when your internet slows down it b/c wither your machine is being overworked or your connection is being flooded.
from my experience, when internet becomes slow, the computer has started taking longer to start up 90% of the time. If this is the case for you, where you have seen a decline in overall performance of your system, you have more than likely been infected by virus, spyware/adware, and have too many programs requesting resources.

press ctrl+alt+del, select the task manager and click the processes tab. then click on the column names "username" two times. this will list all the processes beginning with the ones that started after windows initially started.

if there are anout 20 of them or more than you have programs needlessly running in the background.

you must select all the programs that start automatically and go to the options menu and deselect the box that says "run on system startup"
then run a virus sweep. if you dont have virus, spy/adware, and firewall protection(all 3) then you must get them ASAP. they will save your computer from needing technically assistance as often.

free-avg.com has a great free version that is very easy to use and does most of the work for you

GOOD LUCK

Firefox




Solution:


i) see it depends how application(fire fox) is using CPU or processor, even though nothing is running in the background, firefox will utilize CPU(like background work with going between firefox and CPU or processor which we may not intercept......)

ii) if u are so curious about why it is i will ask you to see a process in Task Manager called "System Idle Process" which will consume about 99 or 90 %(which is a process is not required or doesnot have anything to applications but still it will 99 or 90% percent of CPU) see it has background work with CPU or processor which is not understandabl e by a common person...

iii) i u still think that this is not the right answer try to uninstall fireforx and renistall and check it,  or try some other browser like opera and check whether it is upto your expectations and continue using it and maintain some peace of mind .........


Thankin you

Computer runs slow


Many computers have way too many things running in the background. If you see more than three or four little icons down just to the left of the clock, (this area is called the System Tray), some of these programs could be causing your problems.
Use Windows Explorer and navigate to:

C:\Windows\Start Menu\Programs\Startup
Adjust the size of your Windows Explorer so you can see some of your desktop and drag everything in the Startup folder out on the desktop, and then restart your computer. If this minimizes, or eliminates your problem, put each item back in the Startup folder, one-at-a-time, and restart and re-test your computer until you locate the offending program.

Be sure also that your computer is not virus or spyware infected
