I keep getting this TROJ_DLOADER.DH with farmmext.cab as the infected file. I have removed all spyware, unneeded startups and services in msconfig, cleared temp caches, temp internet folders, etc. afterwards, i run a full sys scan; no viruses found... but it keeps coming back. i've done all i can think of. Any suggestions? Note: WinXP sp2 with all patches.
