Could you tell WHAT 2 downloaders did this, so we can check?
A simple google search, by the way, finds removal instructions for claro-search, for example http://malwaretips.com/blogs/claro-search-virus/
It might be worthwhile to try this (or others you find) before starting that reformat.
By the way, wasn't there a 'direct download' link on the download page? Usually there is. And usually it links to a clean installation program without the CNET installer.
It is a sad day for me, as a long time user and huge fan of CNET over the course of many years. I don't know what has happened to the service we once knew, whether it was taken over or just corrupted from the inside. WHAT I DO KNOW IS THAT OVER THE PAST YEAR, CNET HAS CONSISTENTLY DETERIORATED UNTIL BY NOW IT IS A MALWARE DISTRIBUTOR.
When the installers full of toolbar "offers" were first introduced, they were annoying to be sure, but at least harmless as long as you didn't click through too quickly or accepted the default installation instructions.
BUT THE LAST TWO TIMES I DOWNLOADED SOFTWARE FROM CNET, THE INSTALLER HAS INJECTED MALWARE INTO MY SYSTEM DESPITE MY CAREFULLY UNCLICKING EVERY TOOLBAR "OFFER" IN THE INSTALLATION PROCESS. The malware has hijacked all of my browsers (start page, default search engine and even new tabs all changed to claro-search.com) in an irreversible manner - I have uninstalled the toolbars, purged every registry entry and run virus and malware scans - nothing helps.
I WILL NOW HAVE TO RESORT TO A CLEAN REFORMAT OF MY COMPUTER - AGAIN. THANK YOU CNET.
This is the last time I will ever touch anything CNET has anything to do with. I am bewildered as to why you have turned into one of the bottom feeders of this world, but whatever the reason I don't care. Goodbye.
