I got hit with the Vista Antispyware 2012 virus. I made the mistake of running SpyHunter and now I'm having all kinds of issues. I have deleted SpyHunter, but my Avast antivirus keeps finding a Trojan Horse. When I run a scan on my computer it finds more and more viruses and if I do a shut down and restart, it wants to restore back to just after I downloaded SpyHunter which causes my Avast antivirus not to run. Can you help?
