Hi guys, this isn't necessarily a surface related problem. My dad's desktop rebooted itself while it was scanning using the mcafee. He said he left the PC for an amount of time and when he came back, the PC was refreshing itself. When it came back on, all the programs he had installed are gone including MS Office. And then he said the only thing he did was download Google chrome and then turned off the PC. Now his browsers are hijacked by sweet-page, he has reg clean pro and suptab. and other stuff installed including mypc backup. He can't exactly tell me what happened last night but he said he was playing farmville when this happened. He is also the type of guy who would click any link his friends posted on facebook or ads from facebook/farmville with the reasoning "Hey, it's from facebook, surely this can be trusted!" He denies ever clicking anything last night. So can anyone explain what happened, what could have caused the PC to refresh itself? What could've caused the adwares to install themselves after the refresh when he only purportedly installed google chrome after the refresh. Update: He may have clicked a random link that said Download when he searched for Google Chrome.
