PushOK PUP developers offer us this product as an advertising service, but, in fact, it is just an unwanted application. Unfortunately, PushOK can give you nothing but useless ads and try to gain your money for the fake support. PushOK PUP can reach your computer after of visiting some infected websites, downloading freeware from the web or opening suspicious e-mail attachments. If you notice any signs of PushOK presence on you PC, it means that your antivirus has been successfully bypassed and now your system is vulnerable for other malicious intrusions.
