Hello marvinlzinn,
There's a few things you might want to check.
- Make sure you have administrator rights
- Press win+r (or start > run), type in "services.msc" (without "")
- Services will run and under Services (Local), under the extended tab:
- You should see these: avast! Antivirus, avast! iAVS4 Control Service, avast! Mail Scanner, avast! Web Scanner.
- Make sure all of them are started, if not right click for their properties and choose Automatically (Apply settings) and click on Start.
Next step:
- Press win+r (or start > run), type in "wscui.cpl" (without "") or start > control panel > security center
- Under Virus Protection, search for a recommended Antivirus software.
- If it fails to find any, restart your PC and try again.
Hope this helps, cheers!
