So in summary, my computer had an infection, most things didn't work, fixed some and now the ones that are left are really annoying me.
Here are the problems that I have right now:
-Add/Remove Programs has odd entries and some of them don't have the remove button
-Internet explorer 6 doesn't have the address bar
-Internet explorer 7 gets stuck at "Customize you settings". Can't close or anything unless I got to task manager to end process (thought problem was fixed)
-Internet explorer 7 and 8 opens and then closes (after I tried to uninstall it)
-Some file extensions, such as .dll , doesn't have the "Open" or "Run as..."when right clicked; they have "Cut", "Copy" and so on
-Windows Installer and Installshield doesn't work (for windows installer, it just freezes up and for Installshield error code 0x80040706 pops up)
-When I right click the desktop, and go to "New" all it shows is "Folder", Shortcut" , "Microsoft Word Document" and "Compressed (Zipped) Folder"
-explorer.exe takes along time opening "My Computer"
For the Installshield problem, I tried almost everything that can be found on Google. Most of them lead me back to the same forums that I had visited and lead me to this link .
<----- sorry that was me ranting because it's summer and I don't have much to do and whenever I want to try to install a game it pops up mocking me...
I am seriously getting sick and tired of looking at the same website over and over again for the same frigging problem. And please don't tell me to follow the steps of what the guide said because that didn't work and the same error pops up because Installshield doesn't seem to be smart enough to make their Installshield solutions NOT run Installshield since the problem is INSTALLSHIELD.
So in conclusion, the other problem could be bypassed one way or another, such as using Mozilla Firefox to browse the internet and using Auslogics BoostSpeed to uninstall programs (Apparently, the Add/Remove programs list that's included works perfectly, while CCleaner also has the same problem as the windows Add/Remove Programs).
P.S I want to try to get this fixed ASAP since summers' almost halfway done and I just wasted almost half of my summer trying to fix the problems.
