HP 4520S declares all downloaded files to have a virus

Which anti-virus program are you using ? As this issue do not pertain to the browser rather than your anti-virus. Its quite possible that you have some infected file already in your computer. I suggest you to update the anti-virus program and run a complete system scan and then try to download the files that you are trying previous. Also check if Chrome is set as your default browser because if so it will automatically open the compatible file with it rather than AOL as you desire.

Open that strange attachment in your Hotmail email and your computer may be infected with a virus, a nasty piece of software that may corrupt your computer data, delete files or send your personal information to a hacker. Employ a combination of proactive protection measures and post-virus removal techniques to guard your computer against any viruses hiding in your Hotmail Inbox.

Avoid opening emails from suspicious sources or with unrecognizable text in the "From" or "Subject" headings. And never open attachments that you are not expecting, even if they appear to be from a friend, without first confirming it with the sender to ensure that it is a legitimate attachment. Check the top of the Hotmail page when opening an attachment. MSN Hotmail employs a free virus scanner that scans all attachments when you try to open them. If you try to open an attachment with a Hotmail virus, the website will alert you to the danger. Press "Delete" immediately. Click "Deleted" in the left column of Hotmail after deleting a virus-ridden email. A page showing your deleted emails will appear. Push the "Empty" button at the top of the page to permanently remove all of your deleted emails to prevent accidentally moving the virus back into your Inbox. Run a virus scan on your computer system if you open a strange attachment and suspect that a virus got through the Hotmail scanner. The scanner will identify and remove the virus if it has infected your machine. Virus scanning software is available at a cost from Norton and McAfee, while free alternatives can be downloaded from Avast and AVG. Consult your user manual for scanning procedures, as these vary widely by program. Rather than paying for an antivirus

If you manage to download this file you will most certainly infect you PC with a Trojan Horse, Worm, or Spyware, these virusus remain on your computer copying valuable information and remembering keystrokes and send them back to the creator or host. It is therefore important that you forget about this attachment and somehow find it from a more reliable source. If it is from someone you know I have written a tip on some really good Free AntiVirus programs, (it can be found here: http://www.fixya.com/support/r6790239-virus_infection_best_free_anti_virus), that you can download and install, then run a full scan on the PC with the file. Once the PC is clean the files that are infected can be healed. The file can then be re-attached and sent virus free.

sounds like spyware still got thru even with all the anti-virus programs running. Best thing to do is to save all the important data onto an external drive or flash drive and then reformat the drive and reinstall the drivers for the hardware and put the applications that you want back onto the computer. This time only install one anti-virus program onto the computer.

If you haven't tried MalwareBytes Anti-Malware tool, I suggest you download it on another computer and follow the below guide or you may stay infected.

Once you download the file on another computer, rename the file to something like "anything.exe" with the quotation marks. Now, transfer the file to a usb flashdrive. Take the flashdrive and attach it to the infected computer. Click on "My Computer" and find the flash drive and open it. Double click the drive and then double click the renamed MalwareBytes file. Install the program, let it update and then run the program. Perform a quick scan only, it may take a while so be patient. Once it finishes the scan, click on show results, it will post a list of infections that it finds. Once it posts the results, delete everything it finds. Reboot the system. Two other programs I would install are Avast Anti-Virus which is a free anti-Virus program and Threatfire which is a free utility that actively scans incoming web pages for threats and malware. Below are the links to the download pages.
