This detection relates to BetterInternet, I Scanned
poller.exe with MS Antispy which gave the detection
Trojan.Startup.NameShifter.BK so If its the same then you
have been infected with one of BetterInternet's
wonderfull programs
Go with Pluns suggestion of scanning in safe mode but
poller.exe is part of Aurora which is very difficult to
remove as there is a part that changes its name everytime
you reboot.
Can you do a search on your system for a couple of files
and let me know if you find them, If its Aurora I will
post a few fixes you can use.
Go to Start then search > goto tools on the top bar> then
click Folder Options-> then goto the View tab .
make sure that 'Show hidden files and folders' is
enabled. 'Display the contents of system folders' is
checked & 'Hide extentions for known file types ' is not
checked then press apply
You can set this back later by opening the same page and
pressing 'restore defaults' then pressing apply,
Windows XP's search feature is a little different. When
searching you click on 'All files and folders' on the
left pane,
click on the 'More advanced options' at the bottom. Make
sure that Search system folders, Search hidden files and
folders, and Search subfolders are checked.
Then Search for these even if you find 1 of them it means
its Aurora:
Nail.exe
svcproc.exe
DrPMon.dll
Also check your Add/Remove screen in control panel for
this entry :
The ABI Network-A Division of Direct Revenue
Let me know if you find any of them
Thanks
Andy
