didn’t you never ever have AntiVir on the PC beforehand WITH the GUARD installed ?
→
you might try uninstaling the AntVirGuard-DRIVER “avgntdd.sys”
via ControlPanel → system → Hardware → deviceManager → view? → show hidden devices → Non-PnP-drivers(devices?) →
Rightclick on avgntdd → UNINSTALL
(P.S.: don’t click on anything there if you’re not sure; very sensitive area)
REBOOT
this MIGHT work, otherwise removing such currentcontrol/legacy … services/driver-remnants includes pretty ugly registry-hacks, e.g. regedt32 & setting regkey-rights…
;D ;D 
most of this needs to be done as the REAL “Administrator” !!
