Well i see lots of peoples getting hacked and loosing their money due to trojans and stealers everyday.
So here are some tips to avoid any kind of viruses.
1. If it's possible use Linux otherwise Antivirus/Anti-malware and a Firewall app is a must for everyone.
2. Disable Java plugin in your browser or don't use Java at all as there are many exploits and rats for java otherwise make sure to keep it updated.
Peoples use java 0day vulnerabilities to spread their trojans via java drive by or exploit packs.
3. Keep your Adobe/Microsoft products updated(There are alot PDF/Word and Flash player exploits)
4. Don't click on random links (If you really want to see what's in that link, start browser in sandbox and then open that link.)
5. Don't download and install/open random exe files without doing virus scan that includes new coins and other apps files distributed on torrents or any other site or if possible run them in virtual machine.
6. Encrypt your wallet and write password in a diary or your notebook etc.
7. Use keyscambler
8. Keep your Antivirus/Antimalware updated (I will suggest using Malwarebyets +kaspersky pure) and
please buy them don't use cracked one's.
9. Double scan files and make sure to check extentions as people use extentions spoofers to change .exe to .jpg/.avi etc with help of unicode characters. example:
http://gavii.com/puld/437684076.jpg10. Don't use IE there is a new 0day exploit
11. Use Noscript browser addon
12. If you find some trojan on your pc, make sure to check about it first, as lots of trojans have rootkit functions. You can read about them here. [/b]

If you use Windows for anything money related don't use a cracked version!
