If you have any questions about any of the tools, or any of the "Nasties" you might find, post your questions in the Viruses, Spyware, and other Nasties forum.

your computer speed you say, if you increase your RAM, and run anti-virus and anti-spyware that should speed it up alot!!! :p

I would suggest you go to the microsoft website and download the Antispy (beta) program. I have found that it works well at removing spyware, even thouigh I have a good firewall and antivirus, it still found adware on my system.

be careful though, u can destroy your system if ur not careful in how u use it. If unsure about what to do, then always choose "quarantine" when the scan finioshes and gives u a report on what nasty things are on your computer.

In addition to the above, have you;

- Got enough primary disk space for your page file. I would recommend leaving 2 times the Ram that you system has.

- Disk Defragmenter and disk clean up found in Start - All Programs - Accessories - System Tools. (Worth trying if the PC is a year old or more)

To speed up your computer, you should do lots of things:

1. Cleanup all of the cookies and plug-ins in the Internet Explorer.
2. Terminate unneeded programs on startup.To disable the startup programs, you can click "Start"--Run--Type in msconfig--Under the "startup" tab, you can choose the unwanted startup programs.
3.Detect and fix Windows registry errors.
