yeah we understand your situation , the best you can do is to ask a real life computer tech not a virtual one to restore to a point where your security was compromised,
logme in is ok if initiated by a ms tech , but some techs are not that geeky and need help themselves , i usually ask 2 techs to fix the issue side by side if one can't , nothing to worry if you can still access the system clear off all the logmein downloads
and lock your folder's if your ms tech did not have access to your sensitive files you will be good.
get 2 antivurs atleast for your computer , next time instead of wasting time online , walk to the nearest microsoft certified technician and ask them to fix it , most computer repair center's have this feature . even the online techs will let you know where
you can find a nearest hardware technician , if your hardware chip is undamaged recovery is still possible , don't lose hope.
install minimum 2 antivirus for a normal home computer , for a office computer 4-5 if has high sensitive data and minimum 2 firewalls.
you say you have a recovery point , so give it a try all the best.
if you recovered then backup files clean the hardware disk completely with a hardware tech and ask him to install 2 antivirus and 2 firewalls to protect you from future damage , if possible politely say to a online tech that turning off the firewall is putting
your computer at risk and he may refer you to a real life hardware tech on request.
normally system back will work also most free firewalls and antivirus will create a backup for you if requested you need a complete empty cd/dvd disk or a usb with atleast 16 gb space for it optimal is a 32 gb disk , after you have reached a certain point
in your computer , open the antivirus and click the back up option or use system backup it will back up all of your files into the disk / usb , take the usb and put it in a locker , if you have sensitive info put it in a bank locker . that's it no matter what
computer hardware you lose , you will have access to all your data.
if you are planning to buy a new computer you can always transfer the old data into it.
if you think someone may misuse the usb just put a lock on the backup folder and you are good to go.
if you finished all that create a zip file and put all your backup data in this and lock the zip file . then copy it and put in in 2 or 3 usb's in case you lose the mother backup that's it .
alternatively you can try online backup which will have free drives or you to store data in , if you have sensitive info you might reconsider this cause , there is always a risk of being compromised online.
alternatively you can download backup softwares which make the work more easier by backing up and writing the info directly to your cd.
it can't get more precautious than this .
used the compressed file usb's for your daily use put the mother backup and a zip file usb double check both have uncorrupted files or you will have to recover the corrupted files.
that's it i think , if you take all the steps above you will never lose your data, good luck.!!
