Many telephones these days are equipped with what is called caller ID. A caller ID can usually store about 20 - 100 incoming calls in total. If it is a mobile phone, you should get a report when you receive a bill. If it is a prepaid phone, you will have to refer to your caller ID or pay additionally per month.
Sometimes if it is zipped, (file extension .zip) there is an option on Win Rar that allows you to scan for viruses before saving it on your machine. Just use the virus scanner you want to scan it. But it it isn't zipped, some antiviruses scan icoming and outgoing files (in this case, incoming) for viruses. Also, there is something preloaded on your machine called Smart Screen Filter that checks downloads for viruses. So basically find an antivirus software that checks your downloads for viruses.
