files keep rewriting themselves

These files keep rewriting themselves on startup. My restore function is constantly being turned off and any highlighted dates are inaccessible, so i can't use it! At the same time as Spybot detected these files i found a virus: Win32/Hostblock located in C:\WINDOWS\system32\drivers\etc\hosts, which 'Vet Anti Virus' detects and removes at startup. Does anyone know how to get rid of these 3 files?Thanks for any help.

Hello.

Please produce a *complete* Spybot bug report:

Open Spybot-S&D and start a scan ("check for problems"). After the scan, right-click in the results field and choose either "Save full report to file..." or
"Copy full report to clipboard".

Then attach the file (or copy the report) to the email and send it to: detections(at)spybot.info (Replace AT with @)
