Every time I try to search on google I get the "catcha".? Screen. Where it wants me to enter the word shown. When I enter the word it keeps on giving me another. Ultimately I can no longer search on google. I can search on other search engines though such as yahoo. This just started, and in case it is important, I recently added a yahoo email account. I read somewhere else on my quest to figure this out that there may be some connection. Are there viruses or malware that could be causing this?
Thanks for any help you can offer!
