I did a scan with AntiVir on my laptop tonight, and it popped up an alert for C:\WINDOWS\system32:hvaa.dll. Before I told it to quarantine it, I did a search in C:\WINDOWS for hvaa.dll, and couldn't find anything. Another strange thing is the colon between "system32" and "hvaa.dll". Directory names and filenames in Windows cannot have colons in them, so I'm wondering what exactly did AntiVir find? AntiVir also says that it is the Trojan horse TR/Dldr.Small.ats. I can't find any information on that... any idea on what it may have done to my system?
