I tried installing comodo antivirus. Every time windows starts up, i get a message from windows it can not install comodo because it could not locate a specific file. I tried deleting comodo and reinstalling it but it would not delete and an error message indicating e-mail scanner could not be deleted results. Please assist in deleting comodo so it would not prompt windows for installation.

Hmm… Try stopping the CAV services running (goto control pannel >>> admin tools >>> Services) and disable the e-mail scanner service then do a system temp files and reg clean using a cleaner (CCleaner is a popular one). That’s all I can think of at 6:30 in the morning.
