I am 99% certain that my Computer has been "Unlawfully accessed on many occasions using "URL Manipulation Attacks." It started deleting stuff on my computer, then altering option settings and other parameters on various programs. I believe I know the identity of the major mainstream outlet doing it, but that's another matter. Has anyone got advice?
The best advice that I can give you is, never browse the internet using a USERNAME that has ADMIN privileges on the PC. That way, if you happen to be TRICKED by a website while looking for free software, the website will not be able to INJECT any malicious code. If it does, you will get an alert that says it is TRYING TO CHANGE YOUR PC, and gives you a chance to say NO!
