Well, maybe these softwares installed some adware stuff on your pc which frequenlty collects information about your browsing & brings in the appropriate popups.
If you use firefox, you shouldn't be annoyed with the popups. If you are using Internet Explorer, you should install a
popup blocker.
You can also run a scan for Adware programs using
Ad-Aware or
Spyware Doctor to remove these adware files.
