A user types Russian in a text input area of a Web page but something like this appears on the screen as a result:

38B5 G09=8:C

1. either via its own Uninstall mode in Start/Programs/<that program>

2. if the program does not have such mode, then uninstall it via Control Panel - Add/Remove Programs

3. or remove it with the help of special utilities that find and remove such "spy-ware" and/or "ad-ware".
   Such utilities are often called "anti-spy software", for example, here is one very good and widely known utility of that kind:
     AdAware

   But remember, such helpful utilities are searching only for 'bad' programs/plagins and would never find/expose a normal program such as say Google Toolbar listed below.
   That is, if an anti-spy utility does not help, then revisit items (1) and (2) above.

Here is a list (which I update if a new one is found) of such 'bad' programs/plug-ins that I gathered while browsing Newsgrouops and forums
(for some there are links to Russian-language forums where I found the information, so if you know Russian you may want to read that. Otherwise just believe me and remove a plug-in if you have one from the list):

• Google toolbar

• NavExcel Toolbar

• TopText iLookup - comes with LingoWare
  It was discussed (in Russian) here: http://forum.ixbt.com/topic.cgi?id=24:15220

• Zone Alarm Keylogger

• CommonName - comes with KaZaa.

• InetLookup - comes with Photoshop

• 'speed accelerator' - comes with eDonkey

• eZula
  It was discussed (in Russian) here: "eZula's fault!" discussion

• Webroot Pop Up Washer

• Yahoo! Bar

• SmileyCentral - while being installed also installs Google toolbar (if a user do NOT uncheck that check box during the installation) and thus a user may face this problem with gibberish instead of Cyrillic in Internet Explorer

• BitComet

• Ask & Record Toolbar

• HyperSnap

• Logitech SetPoint - it's a part of a software package that comes with Logitech G500 mouse
  (if de-activation of SetPoint does not help, then you may want to de-activate another programs of the same package - Logitech Flow Scroll)

If none of the above are present or removing them does not solve the problem, then try the following:

• in Internet Explorer main menu click on Tools.
  See if that pull-down menu has an item called "Add-ons" or similar
  (in some versions it's a button "Add-ons" in Tools/Options/Programs).
  Note. You may not have such item anywhere (I don't), it's normal.

• If you find the list of Add-ons, then see if any of Add-ons are marked as "non verified" or supported by unknown sources or just unfamilar (you did not install such add-on). Delete it.
