False. All of you recognized that saying "Rootkits are easy to remove" is like saying "Cancer is easy to remove". Rootkits bury into the very bowels of Windows. The hardest part is to actually detect a rootkit. Once you can see the loading point, the rootkit may be removable. But often the only solution is to reformat, then reinstall Windows and change all passwords.
1. Rootkits are easy to remove.
False. 27% got this wrong. It is a backdoor dropper, or trojan. It's purpose is to install fraudulant antispyware. A virus, strictly speaking, attaches itself to an executable file and spreads when the infected file is copied to another machine or device. An infected thumb drive can wreak havoc!

2. 'not-a-virus:FraudTool' is a virus.
False. 27% got this wrong. The usual cause is a program error. A complex program has many forks where some condition determines which fork is taken. It is impossible for even a first-rate developer to fully test all the possible alternate paths, so even programs that have run without error for years can generate a fatal error when an unexpected combination of factors occurs. Malware doesn't cause crashes unless the malware is badly written.
3. Malware is the usual cause of program crashes.
False. 36% got this wrong. Our Developer Merijn wrote HijackThis, CWShredder, and many other programs. He eventually sold HijackThis to TrendMicro, and the HijackThis team from TrendMicro recently joined us as Developers. Lots of people spell Merijn's name wrong.
4. The name of the developer of HijackThis is Merlin.
True. Everyone got this right. Only registered members can post in most of our forums. For guest spammers, we have a special forum which is accessible by guests but not visible to members - so the spam is all in one place and readily spotted by moderators. Spam by registered members is usually noticed within a few minutes; the spammer is banned and all their posts deleted.
5. SWI Forums are kept free of spam and spammers get banned.
