I was looking at one of the forum suggested videos last week and decided to open X-tube. Very funny, the things some guys do with their dicks!! Suddenly a notice came up on the screen. "Your computer is seriously infected with a virus. I tried to get rid of the notice and it would not go away. Worse still, it then put every application out of action. I had to switch off and call my computer man. I told him what had happened and why and he just laughed. I was so ashamed but when I realized that I had been unable to delete the history! !OMG! I am ready to die!!!!!!!!
Yeah, those are malware scripts. In that case just hit Ctrl+Alt+del and kill the firefox process. If you start it the next time it will usually restore its tabs so you have to do this again. The third time it will notice that it crashes and will allow you to open a new session.
Just be sure to have an anti virus software running and probably some malware liveguard like ad-aware. You can also open your webbrowser in a sandboxed environment which doesn't allow any changes on your filesystem outside a 'sandboxed' area (see sandboxie for this)
I am grateful to you for your comment. Some of these sites are probably the hunting grounds for these web-sharks.
I've had a similar happening on X-Tube.
I would suggest Firefox and these Firefox plugins:
'Web of Trust' - https://addons.mozilla.org/en-US/firefox/addon/wot-safe-browsing-tool/
'Browser Protect' - https://addons.mozilla.org/en-US/firefox/addon/browserprotect/
