Registry issues are not the only cause for runtime errors. Often, the cause such an error is due to a virus. If you’ve ever come across a number of problems with your computer that seem a little odd, it might be due to pesky virus that has found its way onto your computer.
You could be the most security conscience person on the earth but the chances of getting a virus are very high. This is because even opening an email can potentially be a threat, especially one that has an attachment. Downloading illegal files such as videos may also put you at risk.
Once installed, these viruses can do serious damage to a computer. Worse still, some of these viruses may steal personal information from your computer. The SubSeven virus is one example that can do just that. Fortunately, there are telltale signs that your computer is infected with this virus. You may see a runtime error message with the code 216 which is often linked with this particular virus.
Noticing a threat quickly and acting on it should help minimize any risks and potential damage caused. The hypinit32.exe virus known to cause the Runtime error 21 is one that can display a range of odd behaviour. You may notice screen freezing, problems updating or downloading software, problems with connecting to the internet, increased CPU memory usage and problems accessing your hotmail email address.
Usually, all you will need is an antivirus tool to remove this problem. However some runtime errors caused by viruses may require a little more work depending on what programs you use, how vulnerable your computer is and how infected your machine is. This might include trying to source the problem file, reverting to an earlier system restore point or worse comes to worse, reinstalling Windows.
The good news is that there are lots of great free antivirus programs, tools as well as information out there to help rid your PC of these pesky viruses and irritating runtime errors without having to do anything too drastic.
You will find that free antivirus programs generally do not offer as much protection compared to a paid one. But if you rather not spend any money, installing a free antivirus program onto your computer is better than having none. To name a few there are plenty of software companies that offer free antivirus programs such as Avast, AVG and Trend Micro.
