Widows Defender keeps needing to be run

[Guest 112233]

Dear Mr L Rivits

Have you tried Malware Bytes (Free) as a standby test; to look for something nasty.

The other option is will Win Defender run in safe mode try that.

Crap Cleaner. CC Cleaner: run the registry cleaner option and see what comes up. Do not a this stage, delete anything unless you are sure.

I take it Windows Defender is your primary anti malware/ anti virus package - Groogle "Defender restarting repeatedly

Haver you just had a windows update ?

For starters

What version of windows O/S are you running ?

CAT III (Win 7/8.1 user.)

Edit: (Nov15 Post: Norton and Win Defender fighting each other results in this scenario.)
