trojan horse backdoor. dumador. w/ HJT log
 

hi!whenever i connected to the internet, my avg resident shield poped up n said a virus was detected (trojan horse backdoor.dumador.aw) while opening c:\windows\prntsvr.dll
i healed it "successfully"( i also tried deleting it) but moments later it reappeared
i ran ad-aware but it didn't help

*when i clicked the magnifying glass icon to check if my question has already
been asked or not, the virus pops out

here's my hjt log:

Close all (browser) windows & rescan with hijackthis. When the scan is finished place a check in the box to the left of the following entries & click 'fix checked':

Your system needs service packs for both XP & IE6.

Clear out your Temporary internet files and other temp files.
Go to Start > Settings > Control Panel >Internet Options.
Under the General tab click the Delete temporary internet files,
delete all Offline content as well. Clear out Cookies.

Also, go to Start > Find/search > Files or folders > in the named box, type: *.tmp and choose Edit > select all -> File > delete.

Empty/delete the entire contents of the C:\Windows\temp folder and C:\temp folder, if you have one. (Contents but not the folder itself.)

This one too if Win2K or XP.
C:\Documents and Settings\username\Local Settings\Temp\

Empty the Recycle Bin.
