For the first (and last) time I downloaded a Tube 8 clip--and, immediately, an ugly virus, a rootkit, took over my registry, and hijacked IE7 and Firefox.
Moreover, the virus shuts down anti-virus software, invades system restore, and connects to bots, which sends out spam using my email. You're stuck.
So, I had to wipe my hard drive clean and re-install Windows; end of nightmare.
Ya' can't get something for nothing---and Tube 8 makes you pay by infecting your computer.
I've checked on the web for others that have caught Tube 8 administered viruses; the numbers are legion.
