Mouse and PC slowing down when surfing

Hi,

My PC runs on Windows 98 with an Intel 500 MHz processor. I have been experiencing some problems since I got my new ADSL subscription (8Mbits/sec). Before I had a 56K modem I everything was OK.
Problem: after about 30 min. on the Internet, the mouse reacts slower and slower and I have to click more than twice to open icons. In the end, it's getting so slow and inaccurate (the cursor is kind of lagging) that I have to reboot my PC. I have also noticed that the free space goes from 62% free to 45% before I have to reboot the PC to "fix" the problem. I have run an anti-virus (freeware) called A2 to see I my PC was infected with Trojans and stuffs like that. But nothing was found.

What's the problem?

Thanks for your help!

First please get Spybot S&D to clear out most of the spyware.

Short tutorial and download link here:
http://tomcoyote.org/SPYBOT/

Fix everything SpybotSD labels in red.

Then after reboot:
Download 'Hijack This!'. http://www.tomcoyote.org/hjt/
Unzip, doubleclick HijackThis.exe, and hit "Scan".

When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, save the log, load it in Notepad, and copy its contents here. Most of what it lists will be harmless or even essential, don't fix anything yet.

Dear Mobo,
Thank you very much for your help!
I did the Spybot thing and HijackThis. I was able to clean up quite a lot with Spybot.Then I had the Hijack's log read by a guy called "Zero" at Tomcoyote.com. He said the log was OK. However, the problem remains.
Isn't it a performance problem caused by some bad setup of my PC? What shall we do next?
Thanks,
Ced

 

Check under properties for the mouse in device manager and see if it reports any conflicts ..

 

There is no conflict at all in any part of the PC as per the Device Manager
