I have been using my computer normally for the past few weeks and I run Iobit Advanced Windows Care along with A-squared free anti-virus. My computer has been running pretty smooth until the other day I ran A-squared and It was finding some type of trojans that were high risk so I quarantined the items it suggested but now when I restart my computer I have no windows start menu and I can't access anything on my computer. Apparently I need some better virus protection software!! I have had this happen before and I had to reinstall windows completely which I am trying to avoid doing this time if possible. If anyone can help please let me know thanks!
