Please Help!

Thanks for the response.

However, the computer will not boot up at all!  Hence going to the desktop to get to the web browser is not even an option. 

Any suggestions?

i got the e-mail...Thank You!!

BTW, i recall when running the Boot-Time Scan, many that were detected as viruses were not able to be moved to chest or delete. Might you know what that means?

Also, what's the difference between deleting vs moving to chest vs fix? 

Thanks again!

Deleting is permanent, whereas move to chest means you can get them back
