I have been in IT for over 25 years, from first starting out as suppoort, to building and desiging data centers, to large enterprise security and disaster recovery for fortune 500 companies. If I know that a file is safe, I sometimes have to disable the virus checker to install… There is something called false positives. The virus scanner looks for patterns of code if it sees a pattern it thinks it is a virus. So for someone who may be called an idiot, I have never had a system that I was managing, be infected by a virus. Only a person that does not know what they are doing will inflict their own misery.
