Question from Saliu S.: I keep reading about all the computer viruses going around and how they can cause you a bunch of problems.
How can I find out if my computer is infected?
Simmyideas’s answer: That’s a great question Saliu.
The short answer to your question is by scanning your system with a good anti-virus program. I use and recommend the free version of Avast, but there is a handful of other good programs that I trust as well.
The hackers are creating more sophisticated viruses and trojans all the time, and most of them cannot be detected simply by constantly looking for strange behaviors in your PC. The only way to know for sure whether your PC has a virus or not is to run a virus scan with a trusted anti-virus program.
That being said, there are other forms of malware in addition to viruses and trojans that cause problems with your system that are easy to recognize. In fact, you can be virtually certain that your PC is infected with one or more pieces of malware if it exhibits one or more of the following symptoms:
1 – Your computer is slow to shut down or boot up into Windows.
2 – It won’t shut down at all without pressing and holding the power button.
3 – You have all kinds of pop-ups and browser windows opening all by themselves at random times.
4 – You notice that your web browser has one or more toolbars that you don’t remember installing.
5 – Your web browser’s default search provider and/or start page have changed all on their own.
6 – You’re unable to load certain websites and/or your browser is re-directed to websites that you have no desire to visit.
7 – You get a warning that you need to update your antivirus software, but it comes from a program that you never installed on your PC.
8 – You receive a notice that Microsoft or some other “security” company has detected malware on your computer and you need to call them or visit their website and pay them to remove it for you. This notice itself is malware.
9 – Your computer hangs up and becomes unresponsive at random times.
10 – Programs run so slowly that you dread using your computer.
11 – The system operates so erratically that you have trouble typing or using the mouse.
12 – Your computer’s fans run constantly at breakneck speed (you can actually hear the fans running faster than they should).
If your computer exhibits any of the symptoms mentioned above, it’s probably infected with some combination of viruses, trojans, adware, spyware and unwanted toolbars. And unfortunately, there’s a good chance that it’s infected with most or all of them.
If you suspect that your PC is infected, I recommend taking one of these courses of action:
1 – Perform a System Restore using a Restore Point that was created at a time when you are sure that your computer was malware-free. Just be aware that this can be a hit or miss proposition since your PC could have been infected with undetected malware long before you noticed any symptoms.
2 – Restore your system’s software configuration back to it’s factory state, then re-install all Windows updates and your programs.
Note: This will definitely wipe out any malware on the system, but you should only do this if you have all of your user-created data files backed up and stored in a safe place.
3 – This is likely to be the most practical way to handle your PC’s malware infections.
That’s all there is to it Saliu. Just remember that while other forms of malware typically cause issues that are easy to detect while you’re using your PC, many viruses and trojans do not. That’s why I recommend running an updated anti-virus program at all times.
