Laptop warm and slow? Must be a virus! It certainly can't be that laptops are designed to be self destroying dust vacuums. Hell some of them are built to throttle with squeaky factory fresh clean internals! But maybe there's a virus.
Blue screen due to failing ram? Virus. Clicking fan? Virus. Total meltdown of HDD? Fixable just run a antivirus to get rid of the 'no boot drive' virus. Got a virus call from another country trying to steal my bank detail.
Phishing? Virus. Remote shell vuln? Virus. Games installed on family computer? Virus. Entirely obvious malware/adware installed on the family computer? Yeah but you're pointer is a cat now... It can't be that bad. Etc etc
