The latest version of the F-Prot Antivirus definitions seem to be falsely identifying the CCleaner setup as containing the trojan W32/Banco.GL.

Please note that this is an incorrect detection and you can safely install CCleaner. :)

As a newcomer to this forum, I have visited other MS mvp (ie most valuable professionals) forums frequently, and I can assure the folks out there that even the best security software often times incorrectly tags good programs as spyware, adware, or whatever flavor of the month seems in vogue.

It is, therefore, not unusual for the good to be mowed down with the bad sometimes. CCleaner is good folks, rest your bottom dollar on that!

Well F-Prot is known for giving false alarms on some compressed files, however it's usually only if they've been compressed with UPX. I immediately decompress any UPX compressed files I come across, since F-Prot isn't the only av scanner that can give a false warning. There's tons of compressed executables floating about - for instance lossy audio encoders LAME, MPC, OGG, etc.
Complexity of incoherent design.

UPX is harmless. It just so happens that it is free, and convenient for malware coders.

Using UPX, I compressed CCleaner.exe from:
438272 bytes to 135168 bytes (428 KB to 132 KB)

Here is a list of the other compressable files:

--------------------   ------   -----------   -----------
  49152 ->     18944   38.54%    win32/pe     CCHelper.ocx
 180224 ->     76800   42.61%    win32/pe     CCListView.ocx
  40960 ->     15360   37.50%    win32/pe     CCSubTimer.dll
  61440 ->     27136   44.17%    win32/pe     CCTab.ocx
 151552 ->     58368   38.51%    win32/pe     CCTreeView.ocx
  17408 ->      7168   41.18%    win32/pe     lang-1031.dll
  17920 ->      7168   40.00%    win32/pe     lang-1033.dll
  18944 ->      7168   37.84%    win32/pe     lang-1034.dll
  18944 ->      7680   40.54%    win32/pe     lang-1036.dll
  17920 ->      7168   40.00%    win32/pe     lang-1040.dll
  11776 ->      6656   56.52%    win32/pe     lang-1041.dll
  10752 ->      6656   61.90%    win32/pe     lang-1042.dll
  18944 ->      7168   37.84%    win32/pe     lang-1043.dll
  16896 ->      7168   42.42%    win32/pe     lang-1044.dll
  17920 ->      7168   40.00%    win32/pe     lang-1045.dll
  16384 ->      7168   43.75%    win32/pe     lang-1049.dll
  16896 ->      7168   42.42%    win32/pe     lang-1053.dll
  19456 ->      7680   39.47%    win32/pe     lang-2070.dll
  71131 ->     54747   76.97%    win32/pe     uninst.exe
--------------------   ------   -----------   -----------
 774619 ->    344539   44.48%                 [ 19 files ]

That's awesome, no?
The directory took up 1,295,839 bytes before
Now it takes up 562,655 bytes, and the program still works fine (that is the point of UPX ;))

psst, MrG :)

I havent ever had a Spyware tool tell me CCleaner had anything.But that is a good heads up..I think that CCleaner is a mighty fine tool..I Have a Computer Business and suggest it in my forums, and place the program on most of my Clients Pc's..

K & D Technology Appreciates every bit of input and time, everyone puts into this forum and the program its self..

Thank You

It was due to a bad ref file. Stay up to date on stories before you spread false word.
