In order to try to "recreate" what happened, I would have to know what program you originally intended to install. My guess is, you might have mistakenly clicked on an ad for IncrediMail. IF that was the case, and IF IncrediMail is pre-checked by default, it has nothing to do with CNET. But again, without knowing what you originally wanted to install, I can't say anything for sure.
As far are removing it. You haven't told us which operating system you're using. Have you tried accessing their uninstaller by going to Start > Programs> IncrediMail> Uninstall IncrediMail?
Kindly see the remainder of "Uninstall Instructions" at IncrediMail's site. The site is perfectly safe to visit! Additionally, see these instructions.
If you tried the above without success, I would further suggest using the (free) Revo Uninstaller.
Best of luck..
Incredimail has the nasty way to enter your PC, and mostly comes in while downloading a program from CNET. Surreptitiously a window pops in during the installation process that is pre checked with the option to download Incredimail. I was conscious yet yesterday, I missed that. This time it has entered my PC in such a way that I just can't get rid of it. If CNET is part of this operation, I would rather opt out of my choice of CNet as my best tech advisor. Can someone share ways to deal with this problem? Appreciate and thanks very much.
