Could you make better thread titles? You seem to pick a single word as the title of your threads instead of using a more descriptive title. A good thread title should be descriptive yet short. It should be an advertisement to draw people in (those who might be interested), not be vague (which could mean just about anything).
If I were to make a thread like this, I might have use the title "Is Cyberlink a virus?". The example I gave marks Cyberlink as the topic, and defines it as a problem. Anyone who reads such a title will be able to quickly judge whether or not the thread interests them. Using your title of "Virus" however, does not allow for such a quick judgement. It could mean a computer virus, it could mean a biological virus, it mean the movie Virus, etc. Instead, potential readers will need to read part of your thread before they decide if it is worth reading or if they wasted their time reading it... assuming they bother to read at all.
A good way to think about it is to imagine that you work in the business of writing a news paper. If a person only had the time to take a glance at the front page before deciding to buy or not, what sentence could you use as the headline to draw people in without lying to or misleading the potential readers (because they might not buy another paper if the paper gets a reputation for twisting the facts).
