I just recently purchased a new computer and have been watching carefully what I click on, what is downloaded, etc. Now I have started to have some problems. My Norton Anti Virus keeps telling me it has detected and deleted a virus "backdoor.trojan", this always pops up twice back to back. Ran a scan on my computer and I have all the at risk files (adware) that I cannot delete. What do I do? I tried to copy to files, but I couldn't. I'm sure that this has been addressed before, but I could not find anything. Please help as I am clueless when it comes to stuff like this. Thanks in advance for any help/advice.
