Can you boot into "Safe Mode with Networking" by tapping F8 repeatedly while booting up, which may allow Internet access to download and run MCPR. (It runs OK in Safe Mode).
Alternatively, still in that mode, you could try offloading MCPR from the USB stick which may work in that mode
3rd choice, still in that mode, initiate System Restore to go back to before all this happened.
Start > All Programs > Accessories > System Tools
or go to Start > Run and type in rstrui.exe
Or in Vista/7 simply type that into the Start . Search box then click it when it appears above.
Try that and report back please.
Hi Peter (nice to talk to a fellow Brit!), really appreciate the prompt response.
I forgot to say that we run Vista.
We tried running in safe mode - still no internet. When you say offload MCPR from the memory stick in safe mode, at which point should we insert the stick?
Will try the rest this evening and come back to you.
That would be Safe Mode With Networking, not the first choice, plain Safe Mode. Try inserting the USB stick once you are on to your dekstop in that mode. Not sure it will work though.
Otherwise I do know that you can initiate System Restore in that mode because I've done it a thousand times.
Tried the first option, "Safe Mode with Networking" - didn't work.
Tried the second option, offloading MCPR from the USB stick in safe mode - still didn't work.
Tried the last option, system restore - no luck.
Tried it again - still no luck.
Out of sheer desperation, tried it a third time, and....
(Just wanted to stretch out the drama!)
Don't know why, but it 'took' this time and restored back to a few days before the now infamous McAfee upgrade that caused all the problems. Now running like a dream as if nothing had ever happened.
Thank you SO much for your advice.
Only sour note for us is that we only have a month or so left of our current McAfee subscription and we've decided that, if they can do that much damage to our laptop with an update, we are not touching them again.
