Hello and welcome to Just Answer! i am Aitizaz and i will assist you today
is this happening with excel files only?
would you allow me to connect to your computer remotely and try different solutions to sort out the problem?
you would be able to see what i would be doing with your computer.
we are a professional company and we do it as a routine. You can disconnect me anytime you like and i will no longer be able to work on your computer. however, if you still are not convinced, i can suggest certain measures but it will take more time. Decision is yours
There is some problem with the program itself or the files are corrupt and may require an anti-malware software to remove the malware.
We will first try to run a scan to fix the problem if there is any with the excel program. if that does not solve the matter, re-install excel software. Also, i would like you to download MALWAREBYTES, its an anti-malware software that will remove any malware residing on your computer. You should run the TRIAL VERSION and should not buy it.
please do the following:
1. Go to START and type SFC /SCANNOW
NOTE: there is a SPACE between SFC and /SCANNOW
2. Once complete, please again go to START and type the following
NOTE: there is a SPACE between CHKDSK and /r/f
please complete these steps and then try to open the files. let me know the results then
i am sorry to learn that. these commands will not work on MAC. In this case, please RE-INSTALL the excel software, then restart the computer and let me know the result. If possible, please send me any of the excel files that you are unable to open so that i may check if the files are corrupt or not.
OK, please take your time. but if possible, please send me the excel file now so that i may have a check on it
please go to www.wikisend.com and upload the file there. let me know the download link then
