In addition to the removal instructions you’ll find some excellent tips on how to keep your PC safe, so please take a few minutes and read this article in full.

First let’s talk about how Trojan Horse Exploit.swf_c.bac infected your PC

We have recognized several methods in use by this Trojan horse. Note that none of them are unique to this particular virus – other Trojan horses also employ them. We’ll try to outline the most prominent ones, as well as what steps you can take to prevent your PC from coming in contact with the virus.

Spam emails – this has been one of the primary channels for spreading malware and computer viruses for a very long time. Fake email appear to be easy to spot, but this can be misleading sometimes. First and foremost, remember that emails that can actually harm your computer either have a file attached to them or they will give you a link to click on. In the case of Trojan horses both of these are dangerous. Spam emails are not always random jumble of words in broken English – they can be very sophisticated and made to appear authentic either by sticking to a certain theme or employing some sort of scam tactics. Such emails are often targeted at business mailboxes and can contain business related scams – such as filling of forms by clicking on a link or downloading a file that contains the virus.

  • Never trust emails you receive from strangers even if they may appear legitimate. Emails from people you know, but which make little sense, should always be scanned for viruses first. Certain Trojans can send spam emails from the victim’s mailbox without him realizing there is something wrong.

Malicious links and websites – unfortunately there is no clean cut way from which to tell malicious websites and links from real ones, but we can give some guidelines to help. Malicious links&websites often use some sort of url shortener such as or they try to impersonate government websites by using a very similar URL. Thee malicious links usually use some of your browser’s plug-ins such as Adobe Flash and Java against you or some sort of script. It is highly recommended that you keep these plug-ins disabled (they are disabled by default for all newer version of most browsers) and only activate them when you are browsing sites for which you are certain they are safe. You can also obtain and activate a plug-in that disabled scripts for pages you visit – there quite a few of these, simply search for a No-Script add-on. Finally never trust random links from blogs, forums and message boards, especially if they are posted by people with strange nicknames, low post count and no picture avatars.

Torrents and online storage sites are also another danger to your computer – hackers frequently upload virus-infected files to such sites, especially with computer games and programs. The executable file you get from there can be tampered with – they will install the program or game you are looking for, but there is no telling what else they might install on your computer.

An anti-malware solution remains the best defense

People often overlook the usefulness of these programs when they are not threatened by a virus. Unfortunately when a virus does indeed show up it’s already too late. A good anti-malware program will regularly scan your computer and all of your downloaded files to ensure everything is OK. If you don’t have one consider using the one we recommend – you can grab it from one of the banners on this page.
