I had the same problem with puter locking up on some web sites, and redirecting me to ads. Turned out to be Malware on the sites infected my computer. I contacted Ryan and he said it was my puter, which it was, but I was getting the malware from his site (HAMB) so I downloaded a free trial anti-malware program and after a couple of days no more problems. Anti-virus software just doesn't catch or stop this malware and Trojans try Malwarebytes.
