I have a simple little (free) unzip program that I've had for years and every time I get a new computer, I install it. It's quick and easy and I've never had ANY problems with spyware or malware. It's very small - called "Zip Exploder".
Maybe when you get everything cleaned up you might check into that one?
I will check that out. At one time I had an unzip program but somewhere along the way, I lost it. Probably a couple of computers ago.
When I tried downloading last night, it downloaded the spyware and malware at the same time.
