Heres  a trick to check your Anti-virus is working properly


Open notepad (or new text document)Copy this code into the text file

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

then save it (rename) with the name fakevirus.exe If this file gets deleted immediately, that means your anti-virus is working and updated.
If the folder is still visible, you may have to check your virus program settings, and update your virus program, or if you are using a FREE Anti Virus maybe think about buying full Software.

I know freeware programs aren't as comprehensive as full version Software, and have limitations.
Trial version software is a little better, meaning you get the full functionality of the program, but only for a limited time.

Personally, I like an Anti Virus to have a built-in firewall as well as a Spyware/Malware cleaner. Probably asking alot, but I expect to be safe online. As well, I don't think the windows firewall is that great!
I have found a pretty good Anti-Virus/Firewall/Spyware product lately, and it comes with a 2 month trial.
It's called Bullguard Internet Security
