My friend got the virus “security tool” on his computer and im helping him get it off. He tried to go on the internet and download things like malware bytes anti-malware, spyware doctor, etc. but security tool wont let him download anything. He went into safe computer and networking on his computer and when he got to the internet it froze on him and every time after that it still freezes in that mode. Is there any FREE way around this issue?
