I just found out there is obviously a virus on my computer as it has hacked my hotmail account and is sending spam to my entire contact list. I shut down the computer as it was sending even after I changed my password on my hotmail. I've purchased ESET from my laptop, which is now running currently protected, but how do I install it on my other computer, which does not have it on there at all. I'm thinking I'll have to download, but then it will open up the virus to keep sending the spam. Please Help!!!
