Thanks for considering my problem. I realize that when someone with a problem writes a post that is verbose (like mine), it takes some time for responders to read it and to digest the contents. However, I cannot think of any other effective way
to present a problem that is not straightforward. Thank-you very much for your patience.
RE.: YOUR FIRST REPLY (time-stamped 04:26) - - Yes, I have windows 7, 64-bit, with I.E. 9. It is the original (i.e. not a re-installation) O.S. on a new Lenovo laptop. - - The inability of I.E. 9 to respond in any way to my attempts to install the
Acive x components only began after I did the procedure called "REPAIR INTERNET EXPLORER". In my previous submissions to this thread, I called it "resetting" I.E. The procedure is described at http://support.microsoft.com/kb/318378
, and the article is called "How to Reinstall or Repair I.E.". It is accomplished via I.E. Tools/Advanced tab/click reset button. The Start/Help/Search = "resetting internet explorer" resource on my computer says, in part, "By resetting Internet Explorer settings, you return I.E. to the state it was in when it was first installed on your computer." I tried this because someone at the Bitdefender Forum suggested it as a possible remedy to the issue of the "added  prefix and suffix that I have already described in this current BleepingComputer thread.
Before this "repair-reset", done on July 26, 2012, I.E. 9 worked perfectly, except for the prefix/suffix issue. After the "repair-reset", the only dysfunction that I have observed so far is I.E.'s inability to respond to requests to install ActiveXs.
Regarding other problems on my computer, on July 4, 2012, I tried to return the computer to an earlier SYSTEM RESTORE POINT. This failed for all of the dates that I tried. When I tried to use a restore point while the computer was in SAFE MODE,
it seemed to work, but I immediately noticed that all of the software programs that I had installed since buying the computer had become corrupted. They no longer work and will not uninstall. These programs are Malwarebytes, Spybot S&D
and G DATA anti-virus/firewall (although the firewall seems to still work). I.E.9 continued to work without any noticeable dysfunction. Firefox settings have changed, so I will not try to use it to connect to the internet. Another consequence is that
I cannot install new software programs, namely: Opera browser (fails to install); Chrome browser (installs but with an alert that there are alot of errors, so I decided not to use it); Kaspersky Virus Removal Tool (normally it temporarily installs, then automatically un-installs itself when it is finished running. But now, it will not install).
RE.: YOUR SECOND REPLY (time-stamped 05;59) - - Thanks for taking the time to find these resources. I will read them to educate myself; and to see if they can help me solve this specific problem. - - i will then report back in this Forum
Thans a million !
