I am not completely new to computers as I have been using them for about 15 years, but am having a problem I can't seem to fix myself. Every once in a while when we are on the internet we get a message pop up that says "Iexplorer caused an error in .... " and then something about it will now close and the only option you have it to let it shut down the internet. I had a virus scan downloaded and it found 4 viruses that were causing other things to not work, this deleted those things but didn't fix that. So earlier I did a complete factory restore thinking this would solve it and low and behold... IT Didn't!! Now what to do? I am completely baffaled.. help!

How did you do the system restore? Do you have all the MS updates?

Try ccleaner, it's a free registry cleaner/optimaizer, this may help and can't hurt
CCleaner - Home

If you still have error after running ccleaner post the error here https://www.askmehelpdesk.com/spyware-viruses-etc/

I went to that link and it wants money for it and I don't have a credit card...
