Hi Wamaitha,

Have you checked for virus thoroughly .

Is your windows fully updated ?

Check for any background programs running after closign all applications..


virus scanner:
---------------
When you scan for virus,do all the below in both Normal mode and Safe mode.

a) Update your virus definitions in your Anti-virus and run it.

b) Download Stinger from here : http://vil.nai.com/vil/stinger/  and run it.

c) Use this Online virus scanner also : http://housecall.trendmicro.com/ 

Spyware:
--------

Please donot run spyware before running Anti-virus tools and making sure there is no virus in the machine.
Run spyware both in Normal and Safe mode to be sure that the system is free of spywares,adwares and Malwares.

PLEASE GET THE SPYWARE REMOVAL TOOLS FROM THE BELOW WEBSITE. THAT PAQ IS CREATED SO THAT ALL THE TOOLS ARE NOT GUMMED UP IN THIS THREAD.

Some of the experts here have helped in compiling all the important spyware tools and they are listed in this thread
http://www.experts-exchange.com/Web/Browser_Issues/Q_20975384.html

My recommendation would be to start with Spybot ,Ad-ware ,CWshredder.After installing them, First Update them and then run

Once running all the above tools and others given in that thread, download and run Hijackthis.
Download Hijacthis from here http://www.softpedia.com/public/cat/10/17/10-17-69.shtml.
Get the log from Hijackthis and save the log and paste it here http://hijackthis.de/index.php?langselect=english to analyze it. The analyser site is used so that you donot gum up the thread with the entire log.

Remove the bad ones that the site reports. If it says unknown process, then use a search engine to check if those are bad ones. If bad remove them , if you still cannot find then post those files alone here.

Also do this
download msconfig from here and dictate the startup programs
http://www.techadvice.com/win2000/m/msconfig_w2k.htm

open msconfig , go to startup tab and disable all applications except Anti-virus.
restart and then scan for virus and spywares.
