to receive Flash Video in Firefox, and to use my BluRay CD/DVD drive. Those I haven't been able to fix yet, but I also use Google Chrome, though I miss the Firefox Bookmarks accessibility. Unfortunately Blekko installed itself on Google Chrome, so most of the time when I start it it opens 4 browser windows, 2 Blekko, and 2 Google Chrome. I've deleted Blekko, but it is still there somewhere in my Registry, and as you say, Advanced System Care doesn't find it, nor does Avast Anti Virus which dug out another Toolbar virus very well.
The computer is destined for the shop sometime soon to get the functions I've lost to work again, and dig out the Registry entries for whatever the real name of Blekko is filed under in there. I've had this computer running Win 7 for 3 years, and until 3 months ago had no troubles whatsoever.
Part of the problem is that every piece of software now seems to come with a Toolbar attached. Java, which updated today wanted to load one, and you have to take positive action, reading the screens carefully, and being sure to un-tick the always ticked box, sometimes in very small print, asking if you want to download the Toolbar as well. If you miss it, or are busy with other things and don't respond quickly enough, you get it, and all the problems it brings with it.
I think it's extremely unethical behaviour on the part of the companies releasing the software for download or purchase on-line, or remotely updating your computer like Java does. It's certainly annoying in the extreme.
Best of luck Annie Lyn. Cnet has an Anti-virus forum which may be able to help you, but it is always a gamble when you mess with the Registry, and doing a backup now just means that it will Restore to yesterdays problems you were trying to fix. Very, very frustrating.
