Hello Good People!

I'm needing your help once again. Tonight while surfing the net, somehow I got into a whole herd of junk. It all began when about a zillion popups suddenly came to life on a Christmas Site. After closing all of them, I noticed a different icon down beside my clock and I saw it was something downloading from ezula. I stopped it immediately, but junk had already gotten onto my system. No viruses, just junk. I ran my ad-aware and easy cleaner after running a full virus scan. I got rid of all the junk the two programs found but I must have deleted a file I needed as now when I re-boot, I am getting an error pop up message. it says:

WJView Error
ERROR: Could Not Execute Main: The System Cannot Find File Specified.

My computer seems to be running fine and etc but I know that I should not get this error message and as I said, while deleting junk in the program files, I'm sure I deleted this file somehow. What do I need to do at this point?

Thank you for any help or advice you can give me.

Have a good morning
