Free Tech Support Software As A Service
A little known secret is Meraki provides free online tech support software that you can use to manage your client’s computers.
Also, Avast Business is a free business class antivirus solution.
Together, these two software programs allow you to provide comprehensive and remote technical support to business and residential customers.
In addition to the above, I personally prefer to utilize CCleaner (Free version) and Malware Anti-bytes (Free Version) as needed.
