Virus In Latest 1.75 Update for CCleaner in CCleaner Discussion Posted 11 hours ago · Report reply The Google toolbar is not a virus. It was in the Standard CC installer as an offer. (it's no longer there, the CC browser gets offered instead). It's picked up by some AVs as a PUP - a Potentially Unwanted Programe. In this case it wasn't actually the Google toolbar but the new CCleaner browser that your AV has picked up as a PUP and got just which PUP it was wrong, probably because it's also a browser. The main point to note is that there was almost certainly, (never say never), no virus involved, it was just a warning that you may not want to download/install that particular software. (Because doing so would change your browser - which it did).
