Hi. I have Kaspersky Internet Security installed on my office computer, and lately whenever I try to open a specific Excel file, I get message from Excel that says: ‘The file cannot be opened because our virus scanner has detected a problem with the file. ‘ ‘This error may appear because an antivirus program is not allowing the file to open. This can be caused by either: The antivirus program needs to be updated due to a compability problem with this program. There is a virus in the file but the antivirus program cannot properly remove or process the virus that it has found.' I used to be able to continue accessing the file but today I couldn’t access a part of the file. I also noticed my desktop calendar is not showing anymore. I tried rebooting the computer but nothing changed. How can I know if there is a virus, or if it is some other problem? And if it is, how can I disinfect it?
