plz help!!! its become uselessly slow...
and yes.. i dont switch off the pc for days... can this also be a cause for slowness...

post a screenshot of your task manager
eg:

regsvr.exe :\

^^ for windows registry services.

it's a virus and the cause of 100% cpu usage scan with a good antivirus. or download trojan remover trial it should take care of it. This link should help http://amiworks.co.in/talk/how-to-re...oruninf-virus/

format and do a clean windows install
simple!!

is ur proccy a single core or a dual core???
did u try 2 restore ur pc to an earlier point before the problem started??
run the pc is "safe mode" if it still shows 100% cpu usage then do a recovery it not uninstall the 3rd party software from programs and features
also type "msconfig" in start search , go to "startup" in sys configuration and disable every thing execpt little things like sidebar etc(all is better)
then in "services" "hide microsoft services" disable the services that u do not need and then hit ok then restart...hope u already ran ccleaner..all da best

100% usage is definitely bcause of a virus .Format and do clean installation.
Also get the new kasperskyIS 2010 which cost around Rs5xx(3 user license) IF u dont have one.

Well lemme check your Log

It seems that you don't use an anti-virus scanner or your scanner is not active. Only an anti-virus scanner can protect you against new viruses.

I couldn't detect any active process of a firewall on your system. Possible reasons:
(1.) You are using the windows firewall or a hardware firewall.
(2.) You are using a firewall of an unknown vendor.
(3.) You are using a firewall, but for unknown reasons it is disabled
(4.) You don't use any firewall at all.

I recommend you to use a firewall. Download and install one or activate windows xp´s own one. In case you got questions or you want us to add the firewall you use to our database.

Virus Virus Virus! Time to get a good AV.

Not everyone is vellah likeu and me
+1, 10 chars, i second that!
OP: Try combofix, download HIREN BOOT CD, every geek should have this!
