This is Happening All the Time, What Should I Do?
Getting malware in your computer is generally caused by one of three things,
- Irresponsible web surfing and downloading.
- Not having your firewall turned on.
- Your anti virus isn't effective.
The solution to the first issue is to simply be more careful about your downloads. Stop downloading pirated movies and music into your windows! If you must do this, at least do it with a linux Operating system that you dual-boot on your laptop, as 99% of viruses will not affect Linux (you can still spread the virus through your shared files, so it's just polite to have a free antivirus tool in your Linux for the sake of all your fellow file-sharers.
Windows includes a firewall that should always be turned on if your anti virus does not provide a firewall (like the free versions of Avast for example). However, if you surf the dark corners of the web, chances are the threats you are likely to run into are developed by programmers clever enough to infiltrate windows firewall (and that is a sadly low threshold of cleverness). Try one of the many free firewalls available for download. I've had better protection from a firewall a built myself!
Lastly, try another anti virus program! There are many options out there that are either fully free or provide a free trial. You can test alternative anti viruses without having to delete your old one, very useful if you have a few months left on your subscription to a paid anti virus. You could try one of two best known fully free anti virus programs, Avast Home and AVG. Avast is light, easy to use, and measures up well against premium anit virus suites. AVG is one of the few good free options that allows scheduled scanning in the free version. Bitdefender is the best premium anti virus that allows a free trial. It is one of the most user-friendly out there, brings a firewall, and (ideal if you are constantly getting persistent Trojans) maintains a list of free tools for hard-to-eradicate viruses.
So, armed with this knowledge, you can now successfully perform Trojan removal and minimize your Trojan removal procedures in the future if you take the right steps!
