Purchesed SpyBot, it failed, just reinstalled Win8

[Carl2]

I've been using SpyBot for about 6 months time without problems. Within the last week I began getting popup ads at frequently used websites and notices about viruses and excessive popup adds. I used SpyBot to scan the computer a few times but still had the same problem. I found I could not use the recovery image I had created because I need something that will open the file. I tried using the Win8 disk and saving the files I had, but this failed and it put the earlier Win8 OS back in. The last Win8 install was a straight format and install which worked fine and was possibly safer. I have backups of pics and documents still to be put in. SpyBot is reasonably priced but it failed and the internet surely needs more protection, I receive e mail with copies of my banks website asking personal info not issued by my bank, The Microsoft logo is copied by many people so it's also a problem of who you can trust for help.
Thanks for your efforts
