hi im quite new to this and am experencing something called java/byte virus and is slowing my computer down and is really annoying becaue it takes about 45 secs each time to open a window can you plz help me

 

# Click Start | Settings | Control Panel
# Click the Java Plugin Icon
# Click the Cache tab
# Click the Clear button and click OK to confirm
# Note: Please repeat this procedure for each "Java Plugin" button in your Control Panel

But I suspect you have other problems

SpywareBlaster http://www.javacoolsoftware.com/spywareblaster.html
AdAware SE http://www.majorgeeks.com/download506.html
SpyBot S&D 1.3 http://www.safer-networking.org/en/download/

DL them (they are free), install them, check each for their
definition updates and then run AdAware and Spybot, fixing anything
they say.

In SpywareBlaster - Always enable all protection after updates
SpyBot - After an update run immunize

Do these and reboot before the next step.

Then get HiJack This http://www.majorgeeks.com/download3155.html, put
it in a permanent folder (C:\HJT) , run it , DO NOT fix anything, post the
log here.
