I was remote supporting a home office user. When surfing the internet he would keep going to pages unrelated to the address he'd type in. He'd get page not found errors or a random porn search engine instead.
That activity just screams infected with a virus. Right? Based on the evidence presented it appeared something was messing with his connection. Was that not a logical conclusion?
Wrong. Turns out he can't spell. Things like google (he would type www.googel.com), or assist (www.gotoassit.com).
Nice guy, really had to restrain myself from calling him a f*cking moron. Would I have been wrong to?
