Angered

I've had my Toshiba laptop for two years. Used CCleaner on this laptop and previous one I had for 10 years. The ONE time I update (don't always do right away, nor do I want to) CCleaner without paying attention (I shouldn't have to - it should be going directly to Piriform since update pops-up before cleaning) to site it's directing me to, I pick-up Trovia malware. I assume I've gotten rid of Trovia as I removed via uninstall programs and reset home pages on Firefox/IE. I still have lots of certification issues on Firefox, You Tube videos won't load, Google Map shows, but Earth doesn't work (black screen). Explorer (which I never use) works better, however, when just clicking a video on You Tube, the video screen (not my laptop) is black. I'm techno trapped and have know interest or time in learning a foreign language - so, simple 1,2,3 instructions will suffice if anyone can help. Otherwise, I guess I have to pay someone a third of what this laptop cost me to fix what is probably a fairly simple issue for I.T. experienced folks. Thanks in advance for any assistance that may be provided - Tony (Title Edited by Nergal )
