Listen, Opera is anything you want it to be. I doubt there is another so customizable browsers. You can change everything but you may need a little time to learn how to customize it. Good place to start is opera customizatin wiki, I learned a lot there.
Now, in version 9.x opera developers fixed many things that were anoying, most notably history and mht support.
The bad side is that some sites are not going to work with opera, as it follows the standard (acctually, Opera is only PC browser that passed tests for standard compliance). You may ask how is this possible: IE does not follow it, and site authors usualy write sites to work good only in IE. Anyway, you can call system programs from within opera toolbar so it is enough to put IE button there and set as argument current web page, so if it doesn't work you just click the button.
My system is old about 3 years, and I extensively surf warz sites and similar places. I first scaned my system for adware before few days and it found 0. Don't get me wrong - nothing can protect you if you act stupid.
Other then that Opera's cache sucks, so if you use this a lot ( I don't use it at all ) don't use it. _________________

Posting this with opera.
I'll give it a good try this time.I didnt really use it for long the last time.
The only reason I'm kind of reluctant to change is because i alread have firefox heavilly customised and some of my scripts rely on that.
I'll see how it goes.Thanks for all the advice. |

You are welcome.
Note that everything said is only my opinion acording to my knowledge and habits.
You can check out this site too:

| A Computer Virus is a computer program which distributes copies of itself, even without permission or knowledge of the user (Wikipedia). A program, which does harm (deletes your files), but does not spread, is not a virus. AV programs are not designed to check for unwanted actions, but some do try to catch suspicious behavior. Deleting files can be legitimate. |

lol
Yes, there are nice virues too. I heard there are some that do ask users nicely if they are able to delete entire system.
I even got the one that requrie user action to work:
| Quote: | Hi.
You are just infected with lazy computer virus.
Please, delete all files on your hard disk and send this e-mail to all people in your address book. |
| Quote: | Hi.
You are just infected with lazy computer virus version 2.0
Please, send this e-mail to all people in your address book and delete all files on your hard disk after that.
Thanks |

Is there such software that will try and run an exe in some sort of virtual environment to see if the effects would be harmful? |
Absolutely advanced heuristical sandboxing. Almost every modern AV software has it. In the case of NAV, it is called "Bloodhound Heuristics". |

Of course it can be legitimate. But it can also be illegitimate, as I have demonstrated. The point is that the most simple form of harming a computer - deleting key files - may not even be detected by AntiVirus. Sandboxing needs to come to a point where it creates a virtual environment, runs the program, and then checks the integrity of the virtual system. If files necessary to run have been deleted - something my trojan would have triggered - we can assume that the program is malicious. |

I never stated that it's an unavoidable risk. You missinterpreted my rhetorical question at the end. It was as much a question as a statement - asking how you would go about protecting yourself from such a threat. |

A virus is generally written to hurt the host. It often has something you didn't wrote: the capability to reproduce itself and spread. |
No, it's a trojan. A trojan simply executes a payload upon running - it does not run itself, and is usually disguised to make the user think they are running something desireable. It often does NOT work quietly, OR steal any information; more commonly it simply drops a malicious payload to damage the system, with no further purpose than to be mean .
A virus, on the other hand, takes measures to conceal itself, and propagates without the user knowing.
| Grumpy wrote: | | Most of the anti-virus / malware work with a database of known menaces. They can't statically analyze a program and mark it as malware. It is a difficult matter anyway: a program written to synchronize directories is likely to delete files automatically. It must not be flagged as malware. |
Again, not true. Most modern AVs operate as much (if not more) in sandbox mode (virtual environment) than they do in definition scanning mode. Although definition scanning is quicker, sandbox is often more reliable. I know of few AVs that contrain their analyzing to simple defintion matching.
| Grumpy wrote: | | Hey, you can even write a script to automatically remove from your Windows directory a bunch of files you know you will never use... (eg. TAPI drivers). |
Of course. But a sandbox environment would recognize that no harm had come to the computer by deleting these unneccessary files, therefore it would have no reason to be concerned. If, on the otherhand, the entire Windows directory were to be wiped out, the sandbox should, in theory, recognize that the harm had befallen the computer. Unfortunately, the sandbox failed miserably in this case.
This puzzles me quite a bit - why sandboxing wouldn't catch something so blatantly obvious as this script. |

You could consider using a HIPS (a host-based intrusion-prevention system)
For example: There is an excellent free version of System Safety Monitor available.
Or: use a good Hosts file (to prevent connections to certain sites), or even better, something like PeerGuardian (free IP-blocker)...
With a HIPS and an IP-blocker installed, you can be almost absolutely sure nothing runs you don't want to run (or more specific, what it is allowed to do), and an IP-blocker prevents unwanted connections.

There is aways going to be code out there that will slip past AV programs, unless every system runs with Vista's approach, ask permission to do everything: "Are you sure you wanted to press the "e" key? click yes or no."
