It's even worse when you are the "family/friend techy", and expected to do it all for free, including complete re-installation of OS (often without any media with said OS on it....), recovery of data (in some cases just a handfull of files in the exact same folder as the 134 virus infected porn files, in once particular case. lol).... Usually all because they used the copy of McCaffee their ISP provided for them....
8 Hours later, often including having to put their drive into your own PC to get the data they want to keep and disinfect it, you finally finish.... They get it home, uninstall the improved AV software you have put on and put that ISP provided McCaffee back on, then phone up and have a go that since you did it their PC has slowed right down.... Ignoring the fact that until they put said McCaffee back on it was actually 8 times faster....
Or there's the one where you are handed a literally DEAD PC and asked to fix it..... You know, a fix that requires a new motherboard, cpu, psu, hard drive, optical drive, PSU, memory.... I tend to just give my mum our oldest family PC every time we upgrade ours these days. That way I never get that "my pc is dead/stupidly slow" phone call.... Did I mention the fact my mum likes to fill her PC with BT provided software, like McCaffee, BTYahoo browser as was etc etc etc... lol Then there are my sister's boyfriends/lodgers/husband over the years with their hard drives full of porn files, with, you guessed it, McCaffee...... I literally detected 134 viruses/malware on one of her lodger's pc's once..... "You'll fix it for him wont you son..."
Sigh.
