Hello,

I got a suspicious e-mail yesterday. It was a reply from my dad to my last e-mail I sent him. The new part was the following:

Here is an update of the project.
https://drive.google.com/…oad
Archive password: 1331

I was not really paying attention and I clicked on the link which goes to
https://drive.google.com/uc?id=118vfbqwGRK2baMkrWRG4TNBB4E7VzfaU&export=download

I downloaded it and tried to open it, but the password was needed. I (fool) typed the password from the e-mail. The downloaded .zip archive did not open, but a warning window popped up (something about failing to open the .zip, I think).
Then I realised something is not right. I deleted the .zip archive and I ask my dad about the e-mail. He said it was not from him and the same email (attached as a reply to different conversations) was sent to a couple of his contacts (I don't think anyone else has opened the file).

After deleting the file I ran a couple of tests with my AVG. It has not found anything yet.
My question is how can I be sure that I do not have any malware on my computer? Or if the file is really somehow dangerous? I googled it, but I have not found any satisfying answer yet.
