I mistakenly clicked on suspicious button on internet. Result - internet jammed until I click on 'you have won a prize from BT'. Did not click. Turned computer and internet off. When turned on, box still there.
Want to go back to previous state using Time Machine.
Q1 will it work to eliminate problem?
Q2 Just found out how to back up using Time Machine, but it says my Mac HD will loose everything on it. I thought Time Machine was there to save everything, not to delete it.
I have Mac OSX 10.7.4. Startup disc Mac HD. OS X lion. ( I am in another room, using someone else's PC)

Given that you use Lion (OS 10.7.4), there should be an invisible Recovery Partition on your internal HD. So, you need to boot to that partition by holding down the Command and R keys when you start up your machine. This link provides the information you need:

https://support.apple.com/en-us/HT201314

From that link, it looks like you would need to 1) use Disk Utility to Erase, Format, and Partition your drive, 2) re-install Lion (the download they describe should give you the last version of Lion that was available, which was 10.7.5, described here:

https://support.apple.com/en-us/HT202496

and 3) use Time machine to retrieve all the non-system stuff from the Time Machine backup/backups.

If the recovery partition is not there, or you can't get to it, assuming you have the Lion DVD, you should be able to boot your Mac from that DVD, by holding down the C key when you start up your Mac (with the DVD in the drive), and follow the same steps above, except that after you install Lion (I assume it would be OS 10.7), you would need to apply the OS 10.7.5 Combo Updater, which you can get from here:

Hello and welcome.

Before attempting a restore from Time Machine, you could try downloading, installing, and running the following to remove the adware:
Malwarebytes

You may have to download it on another Mac and transfer it using a USB flash drive or external hard drive. Let us know if you have any trouble getting it installed.

Thank you, that sounds great. I have actually used another log-in which seems unaffected. However, putting all my data

Thank you very much for your help. I have downloaded Malwarebytes, but it has found nothing on this log-in (which isn't the one that has the problem) I will try

malware bites has found nothing wrong on original login. The internet is completely frozen except for this notice, which I won't click on. And now I have message, 'Unknown error in scanning process'.

THANK YOU! I downloaded and read info. at Malwarebytes. All I had to do was open Safari holding shift. It worked a treat. Can't thank you enough.
