virus or malware on PC677

 Hello,

it is improbably, bit it is possible, e. g. Stuxnet.

It is recommend, to archive your project and copy it to an external hard drive. With an clean PC you can check, if the project includes vires or malware.

After that you have to recover the virus diseased PC with the recovery DVD. Then copy the checked PCS 7 project to the new recovered PC, dearchive it and test it again with the PCS 7 compatible virus and malware software.

The best way is, to have a PCS 7 archive, which is generated before the infection of your PC.
