I tried Kasparsky and AVG, which didn't find the virus. Tried "search and destroy", which is anti spyware, that found stuff, but didn't remove the virus.

I think there is a virus on the computer. So lunched the wire shark and analyzed the results:

Which a TCP stream that yield :

That is a popup virus. If you save the

html to /html

in

file.html

And open it in browser you see it. Now, my question is, how do I further detect where the virus is and how to remove it from the system? Running on Windows XP SP3

    In addition to cleaning up the spelling and formatting, it would help if you could provide more information. What kind of OS are you running? What symptoms lead you to beleive there's a virus? A web based threat like a "pop up virus" is going to present differently than a trojan or worm that's actually on your computer.

The one any only true answer to removing a virus from a computer: "Nuke it from orbit, it's the only way to be sure". Which roughly translates to wiping and reinstalling. You may want to take an offline image of the machine first so you can recover important files and such.

Once a system in comporomised you can never trust it again. You don't know if the virus is still there, or what it has changed; you can't trust utilities to remove virii, they are meant to prevent, not remove.

It's worth trying combofix and mbam, both fairly capable malware cleaners, the first being the most thorough.
