Many flavors; suites, free and paid, free antivirus, paid antivirus and so on.
Whatever you decide, here is a link to a company that performs comparison tests between antiviruses here: http://www.av-comparatives.org/ One of many such 'independent' testing labs available.
It is a good guide to use to make your best decision.
NOTE: As long as you appear not to have an antivirus, suggest using another computer to post here until this issue is fixed on the other computer.
To completely remove all traces left over from uninstalling any antivirus program, go here: http://singularlabs.com/uninstallers/security-software/ Uninstall first by Add/Remove or Programs and Features, then use the vendor uninstaller to clean up the rest.
Be sure to reboot after to ensure all old files are removed. Removing all old files is important to prevent conflict, and improve stability and performance with whatever you choose for your new install.
Have Windows Vista Home Premium SP2 Dell Inspiron 6400. Nothing fancy; use it for email, general net use and watching sports.
I recently received the following message "Couldn't start the Security Essentials service: The specified service does not exist as an installed service".
Read that the MSE is horrible so I ran "rkill" and then ran Malwarebytes Anti Malware. Then I ran Superantispyware.
Will uninstall MSE so what anti virus program should I have? Is Avast still good?
