Happy to help.
Hi Bob, well i spoke too soon.
what a nightmare ive had thanks to avast download totally buggering up my laptop.
its taken 22 hours to wipe and clean instal 7 then upgraade to 10 again.
all i can say for anyone reading this is avoid safe mode like the plague in windows 10.
spoke to avast and paid for 2 years licence. key auto added to my account but then i noticed i had no firewall. checked and since the licence key was auto sent my premium had reverted back to free version.
spoke to support who sent me link to download their cleaner tool to be used in safe mode.
10 minute job i thought, heck no.
once in safe mode the cleaner tool shortcut was not there to run. tried to get out of safe mode and it asked for windows master password and kept telling me it does not exist.
spent 2 hours last night and 2 hours this morning and no matter what i tried i could not get it to accept my password which worked earlier as did fingerprint. avast wanted £99 for premium help but lowered it after i eplained it was initially avast that caused the problem after they had sent the key.
long story short i had to do a total clean win 7 install and upgrade to 10. i lost all my passwords that had been extracted from avast to desktop.
note to self. safe mode is now a no go area just in case i cant get out again.
