A few days ago I visited some first-time clients. There were two computers - an HP laptop and desktop, both running Vista (I know!).

The desktop problem was fine - removed some rogue spyware, did other cleanups, and all was well. I return tomorrow to install the max 8GB RAM as the client wants it smokin'! lol

Did the same stuff to her hubby's laptop. The ONLY thing I did differently was to let disk defrag run for a while, and then stop it part way thru as they were going to run it regularly.

I get an email saying that some of the laptop's programs, including iTunes, will not open.

What the heck could have caused this? It has the maximum RAM - I was asked to look at it because it was running slowly. Scans turned up no malware or viruses.

HELP.

Thank you!
