My thinkpad t61 with vista sp1, creates strange entries in services.msc since i bought it.
There are some examples bellow listed.
2009/5/20, Hdaoteaue created.
2009/5/5, Sym_996 created.
2009/4/8, Exfatrsnt created.
2009/3/31, Viarvmtsmtl created.
2009/3/30, Gys55clpp created.
2009/3/19, Hdaknempfrn created.
2009/3/6, .netvewi created.
...
All the strange services are DISABLE by default.
All drivers and windows updates are up-to-date.
NO spyware, virus or trojan are beeing found.
My softwares installed are normally, NO illegal sofz.
I delete the entries in regeit, located HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\, but about two weeks later then, the STRANGE service will create again.
