I am running an Acer Laptop bought in Hong Kong. The operating system is Windows 7 Home Premium. I am based in Beijing, China (I am not Chinese) and am no longer able to connect to the internet via a VPN, so my connection is unencrypted.
Over the past few months I have had a few experiences that have led me to believe that my computer has been hijacked. This includes unrequested and unexplained restarts where I have found, for example, that all programs that had been running previously had been restarted. This includes chrome, but the pages were not the ones I last had open (i.e. when chrome was restarted it loaded my default startup pages, not the tabs previously open).
I was getting concerned about these weird occurrences so, over the last couple of days, I have been trying to run a plethora of malware scanners. I have tried in ordinary and safe mode. Many find nothing. Microsoft Security finds nothing with a quick scan. However, on many occasions with different scanners, including Malewarebytes and Microsoft Security Essentials in full scan mode, the scan runs for a few minutes and then the computer suddenly switches off completely (not a normal, controlled shutdown, but a complete and sudden switching off).
This has kind of confirmed my worst fears, especially given where I am living, and I am really at a loss what to do. Can anyone help?
