Virus / Malware Removal Checklist
We have had a rash of computers grace our office with some type of malware on them. If you believe your computer or other computing device (ie phone, tablet) give us a call right away. You could potentially be hemorrhaging sensitive data across the network without knowing it. I thought it would be informative to show the checklist we go through in the removal and repair process so our clients can get a feel for the work involved.
