Oh scanning afterwords is always a good idea, once the machine is “clean” i usualy run something to scan it anyways, once in awhile I’ll miss a registry entry etc…
Depending on the virus it takes anywheres from 10mins to maybe 30 to get rid of it manually. It requires keeping up on a lot of the diff types of files and locations they like to affect, but Its nice to get rid of it that quickly and spend more time on making sure it’s running correctly, and cleaned up so when the customer gets it back its like a brand new machine. and also much less prone to other virus attacks. A lot of good free alternate DNS services that block malicious websites
We are veryy thorough
