So my malware has recently been blocking svchost.exe from running as it detects it as a threat. However I'm not sure whether I have a virus or not. I am really not sure what to do. Furthermore, when I run scans, nothing shows up. Any ideas?

1. Configure exceptions for specific processes. 2. Address your question to vendors support forum. Rgds Milos

Yes you're infected There are two rootkits that may be a cause zero access & TDL4/MAXSS (mostly pihar ) Download http://support.kaspersky.com/downloads/utils/tdsskiller.exe and scan your PC.If you still have issues contact malware removal forums. good luck

Hi, I suggest you update your anti-virus program or use another one to scan the system in Safe Mode to check the virus. Also you can contact their support for help. Regards, Vincent Wang TechNet Community Support
