I have had some sort of alert come on my screen from Microsoft Internet
Explorer, saying data or system errors, recommended scan by System Doctor
2006. Is this genuine,
No, it isn't genuine.
It's an ad, intended to scare you into giving them money.
do I have something wrong on my computer,
Only the ad and a lack of popup blocking software. It *is* possible that
your system has some minor adware infection, but that app will not fix it.
or what.
Should I download this software
No, you should not.
You should use a popup blocker, though, for example the ones that come with
Google or Yahoo toolbars.
Also, get and run ccleaner -
www.ccleaner.com - this will clear the
temporary file folders, which is where much of the adware type infections
take root from. Once it's installed and you have set it up and run it
once, run it regularly by right-clicking on the recycle bin and choosing Run
CCleaner. This will take a second or two and will not interfere with what
you're doing.
