I find that all do not follow any tips or suggestions, or keep on demand scanners updated etc. Along with regular computer or disk maintenance in that regards. We all know when we service the computer if a few programs that we might of installed and explained how to use, and "check for updates first" etc.... like Spybot, Spywareblaster or Malwarebytes if the program has been updated since our last visit.
So as far as you'll be getting less repeat customers when handing out "tips for prevention...." is not going to happen with probaly 98% of them.
had one customer i serviced,,2 weeks later she called, "I'm infected again" told her "geeeeez, i installed 5 layers on protection on that desktop, and your telling me it went thru all of it,,,, hummmmmm, of I'll recheck it for you". Asked her does anybody else use this desktop (kids??) she said no, "i just use it for business". When I returned the desktop to her, she asked me to check/service her laptop (said it's not running right). got back home with it, would not boot, got it to boot, and the first thing i seen on desktop were shortcut links with the word "Nigeria" within the links!!! called her up and asked her about those shortcut links,, she stated... "oh thats where my business is at"!!!! her laptop was so badly infected had to re-install the OS. Of all places, Nigeria! and to top it off, the business she is in is a "Pyramid-networking" type of business selling video phones to!
So they are going to do, what ever they are going to do,, they going to click what ever is in front of them with no regards to safety.
yes, i do hand out and explain "tips for prevention", feel it's party of my job
