Malwarebytes Anti-Malware

I received this error msg trying to install Malwarebytes Anti-Malware.
error 718 (-2146893798, 0)

I was trying to use the procedures given in this forum for cleaning a PC. I stopped the process after this error, until I can get a reply on what this means and should I just proceed to the next step of Combofix and MGtools. The error for Malwarebytes Anti-Malware never allowed me to use the program - even in Safe Mode. I did change the name to mb.exe. The previous steps have not yielded much except Spy bot did find 19 items which I cleaned using your directions. SuperAntiSpyware did not find anything.


Thanks for you help.

My PC specs are:
XP Home SP3
ZoneAlarm free 7.0.483.000
AVG free ver 8.0.138
Firefox 2.0.0.16 (primary)
IE 7.0.5730.11 (use occasionally)

 

Thank you

During a recent scan with AVG, it found a Trojan, Dropper.Agent.JOC. Usually it finds cookies or nothing. I just wanted to make sure.

 

I've since deleted the entries, but yes it was removed. There were about 4-5 occurrences stored in various areas. I still have one more of your procedures to run, MGtools.exe.

One more question. I mentioned that I received an error msg trying to run Malwarebytes Anti-malware. I listed it in my first post in this thread. When time permits will someone address that?
