Sometime you get a spike....for example, when you moveyou Mouse over an icon.

But otherwise......dunno..maybe

do you have anti-virus software installed? if not www.grisoft.com do some free stuff, very good, do an update then scan.

also, try http://windowsupdate.microsoft.com and see if there are any critical updates available.

what OS? what programs running?

xp pro and i only have msn running :S it was fine yesterday jst 2day it got it

if you right click on the task bar, go to task manager, see what programs are running, and look at the processes - you can sort it by CPU usage, see if you can see what process is using the highest CPU time...

DLLHOST.EXE
is the main 1 that is using the most its on like 93 :S

from what i can find in a google search, yes you could have the MSBlast or Welchia worm. you will need up to date a/v software to scan your computer and it should tell you for definite if you have a virus or not.

waht program shall i use to find the worm?

**joshwa** · 05-09-2003, 04:06 PM

to find welchia:
http://securityresponse.symantec.com...oval.tool.html
to find msblast:
http://securityresponse.symantec.com...oval.tool.html

just for some free anti-virus software : AVG Anti Virus:
www.grisoft.com

very good easy to use, keeps itself uptodate. good idea to have it on your pc whether you've got a virus or not. should also find blast/welchia if you update it after installing

where do i go on them 2 sites to terminate then virus if i have one?

**joshwa** · 05-09-2003, 04:20 PM

you need to run this:
http://www.symantec.com/avcenter/FixWelch.exe
and then run this:
http://securityresponse.symantec.com...r/FixBlast.exe

just to be on the safe side
