Browser hijacks can be very dangerous, I have dealt with many of them. The last one I had was a malcious piece of malware reminding me my PC was infected with a trojan. When opening my browser I had the choice of downloading various programs to clean my system. At this stage its best not to log into anything. Feeling a little pissed, I cracked the programs and emailed the companies with the affiliate responsible.
The malware consisted of 3 reg keys, 2 excutable files, and was lodged in my startup. Though the various spyware programs I run would pick it up and delete, on restart the malware would load again except now under a different path. I eventually stomped on it, and put it into my archives.
Malware in a nutshell can be very dangerous, logins , passwords, bank accounts, ect.. can all fall prey to malware. I felt my actions takin were justified. greek39
