Hello all, Someone has asked me to take a look at his computer Win XP, a month ago a large banner type flashed up and proclaimed at start up "Your System is Infected with Spyware" and does this ever since, this large banner just sits there all the time, I went around and tried to get Ad Aware on the the case and Avast etc all the stuff to try and remove the bug but no luck, after downloading and trying to run the programe the message comes up "you do not have permission to install this on this computer" and it does this with everything System restore, windows update, it keeps on giving the same message no matter what you try it will not allow anything to be opened yet BT Yahoo works fine as does the Internet. I have tried to change users this make no diff, I feel sure that the problem can be fixed if the proper software can be installed and run.
It sounds as though you have an infected computer.
Get him to download HijackThis from click here. Make a new directory called C:\HJT and place the exe file in that directory.
Now run the file by clicking on Scan. DO NOT ATTEMPT any self-medication as a lot of the entries that are shown are good, indeed essential elements. Instead choose to save a log file and then using copy and paste techniques, post it together with a description of his symptoms at a MalwareRemoval site
