Microsoft Tech Support Scam
Nowadays, there are two of the most extensive ways of malware spreading – lure emails and injection into a hacked program. While the first one is not so easy to stay away from – you must know a lot to recognize a counterfeit – the 2nd one is simple to solve: just don’t utilize hacked programs. Torrent-trackers and other sources of “totally free” applications (which are, actually, paid, but with a disabled license checking) are just a giveaway place of malware.
