NAV has also never found any virii on my system.
It never finds any on my clients computers either,but other AV's do so don't trust Norton.
Now as for JS/Loding.B :
Loding.B is an e-mail worm, which like VBS.Loading.A , spreads a link to a location of the code (instead of the code itself).
The worm is activated upon visiting a web site containing the worm script, an html page loading and executing it.
When activated the worm sends an e-mail to all addresses found in all located lists on a user's system.
The Subject line of the message reads:
" Hi ! "
The message body reads:
" Hi, how are you ? I am fine here. Please read the page
[the url to an affected site ] to get some knowledge and prevent
somebody hack you. Forword this mail to help all your friends too."
Also, Loding.B changes the Internet Explorer Start Page and points it to the affected site.
I delete the C:\Windows\Temp Internet folder regularly and Windows puts a new one back when the browser restarts. If you are still unsure about deleting the whole folder just right click each infected file and delete each one. (might need Safe Mode) You did not say which version of Windows you're using.
Current systems: WHAT OS, BackTrack-raw, PCLinuxOS, Peppermint OS 6, Kali Linux
and a custom Linux From Scratch server hosting a bunch of top secret stuff.
