My usual start site, Tsninternet.com.au has been hijacked by syssecuritysite and will occasionally divert to a [bleep] site.
I ran AVG and Windows Defender and also Windows Live.
Windows Live came up with three viruses and then cleaned up and reported all is well.
I then tried System Restore but this syssecuritysite is still coming up instead of my usual home page.
I went to Tools-Internet options-Use Current page but to no avail and now I have a yellow triangle on the taskbar telling me my system is infected
