"nasty pop-up boxes in Firefox and Chrome"
Worked OK (used only occasionally) in its proposed function
Two months after I installed it, nasty pop-ups began to appear in both Firefox and Chrome -- all kinds of ads and even a computer scan to accelerate Windows. I checked configs in both browsers (both were set to kill pop-ups), freaked out, ran a system scan with Norton. Nothing helped, and I couldn't figure out where these pop-ups were coming from. I finally decided to check my installed programs, and chose to uninstall 7-Zip. All pop-ups ceased immediately.
If you can live with all kinds of pop-ups in your browsers...
