Tripscaused this started making posts about his experience in tech support. i posted this as a comment, but realized that i could share with that many more people this way.
i work for the tech department in staples. here is my biggest, "damnit" story:
>started about a month prior
>one of first shifts where i am on my own, the only tech in store at the time
>customer brings computer in
>says it won't connect to internet via wi-fi, but will work on Ethernet
>we have an intake scan on thumb drive. my first instinct is that this would be a virus, but while waiting for intake scan to start up begin basic troubleshooting.
>all i managed to do was run the windows troubleshoot and it did not find anything wrong.
>customer getting impatient with me.
>decides to take computer home before we can complete the scan.
>inform diagnostics and cost. doesn't want to deal with cost. takes computer home
>about half an hour later
>calls store, absolutely pissed off
>making outrageous claim that i made the computer worse
>inform him that i changed no settings and made no changes to the computer in any way
>still blames me.
a few days later tech manager informs me of what happened:
>turns out his computer had multiple viruses, including some really nasty ones.
>manager also informs me that while it wasn't my fault, my diagnostics did cause the issue to worsen
>turns out that the virus was just blocking wifi, but when i started diagnosing it and running the virus scans the virus "lashed out" so to speak and crippled his computer even further.
