After 13 minutes and 30 seconds, total PC lock-up. I had to shut off the PSU in order to get it back working. Worthless item! Avoid at all costs! I was expecting it to work, a quick plug and run and solve my problems. I've tried running anti-virus, no luck, and three different malware software, only one did anything. It found 36 problems but the adverts still persist every few minutes.
Bottom Line: No, I would not recommend this to a friend
