Why dont you try re-installing windows 98 from the back up directory. This might fix all or atleast some of the problems. I'am not a computer expert but it has worked out for me

I have downloaded Spy Sweeper and the problem has gone.

Glad that worked for you. Traditional anti-virus programs don't do a very good job of detecting "spyware", so you do need to run anti-spyware utilities in conjunction with your AV utility

Here are some simple steps you can take to reduce the chance of infection in the future.

1. Visit Windows Update:
Make sure that you have all the Critical Updates recommended for your operating system and IE. The first defense against infection is a properly patched OS.
a. Windows Update: http://v4.windowsupdate.microsoft.com/en/default.asp

1. Adjust your security settings for ActiveX:
Go to Internet Options/Security/Internet, press 'default level', then OK.
Now press "Custom Level."
In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to 'prompt', and 'Initialize and Script ActiveX controls not marked as safe" to 'disable'.

2. Download and install the following free programs]

b. SpywareGuard: http://www.wilderssecurity.net/spywareguard.html
c. IE/Spyad: http://www.staff.uiuc.edu/~ehowes/resource.htm

1. Install Spyware Detection and Removal Programs:
You may also want to consider installing either or both of AdAware (free version) and Spybot S&D (freeware). Use these programs to regularly scan your system for and remove many forms of spyware/malware.
