My PC is sooooooooooo slow I fear it's inherited another virus.

I have a Dell Inspiron 530 with Vista so never gonna win any races but it does it's job ok.

Norton slows it down further but still ok, but now it's pathetic and can take a minute to load a page - in fact it still hasn't loaded all the smilies yet on this one  

I have Spybot, A Squared and Ad Aware and run them regularly but it's no better.

Suggestions please.............

Check the amount of used space on the HDD. Tolerate no more than 85% full.

How much Ram has it got?

What was the last application you installed?

A simple suggestion, throw that POS Norton away It's a system hogger, an up to date version of a free AV program like AVG or Avast and your windows firewall will be more than enough.

Oohh yes - be very carefull if trying to remove Norton. If you don't get it just right you will have a mess that needs hours of web surfing, file deletion and regisrty hacking to sort out.

...so speaks the voice of painful experience

okies .. you have something running quite hard in the background ...

cntrl+alt+del again .. then hit the "processes" tab along the top ..

now click the CPU box twice .. this will put the column in to usage order ...

top one should be "system Idle process"   the others might now flick about a bit .. youi ned to read what processes are working whilst you do nothing .. don't touch mouse/keyboard and have as many other programmes turned off as you can ...

Best way to remove norton is to download the "removal tool" from the norton web site .. ridiculous I know .. but it actually saves a load of hassle in the long run ...

I think it has 2GB and physical memory used is 47%

Some other data that may help:
OS (C) 241GB free of 288GB
Recovery (D) 5.86GB free of 9.99GB

MSMXL 4.0 SP2 Published by Microsoft Corp 1.26MB was last install.

If you have upgraded to to the latest SyBot then you will find an additional icon in the task bar or system tray (bottom right corner). I can't remember whats its called but had the same effect on my PC. So I uninstalled it and went back to the old version and hey presto; speed restored.

When looking in Task manager look at what is using the CPU you probably have [in processes] something there that is hogging power  eg svchost.exe there will be several of these if one as a crazy % like could be 90% delete it!
Also as someone said previously norton is a system hog  Try the AVG freebie it will do the job
Also you may have lots of programmes starting up in the background that you dont realise ....typr msconfig in RUN box & go to start up tab & untick some .....link here for a guide to what you can safely shut down..
