the other options are root-kit detection programs, that are specifically designed to detect those nasty things

Also I recommend a real anti virus program those free ones really are not as up to date as most believe, they lag quite behind services like Norton or McAfee, hence why they can still charge, besides 50 bucks for a whole year or even less, is worth it.

in ALL cases its a cat and mouse game, generally a virus infects before its detected.

one really nice anti virus I like aside from Norton is ESET NOD32, it is actually a really nice program, with commercial level security such as heuristics

Symantec's SONAR detection is actually useful for detecting things that might be a virus, by detecting what they are doing, you will still get false positives but rarely, and better safe than sorry.

if you KNOW what you are installing like AI Suite II I believe that gave a false positive (ability to configure hardware) which if a virus could be bad lol. you just override that.


keep in mind that none of this is better than the following:

always scan downloads from site that are not trusted, (porn sites, torrents etc.)

also scan files you get from others, not that they have bad intentions but you never know if they have a virus. (also keep tat kind of file sharing to a minimum)

stay away if possible or at least run our browser in private / in a sand box mode) if going on some less trustworthy sites (porn mostly and almost ALL sites) some may not be that bad like playboy etc, but lets keep this somewhat PG lol)

keep virus software updated, try to consolidate, by using one brand for other security, some security software can cause conflicts when used in conjunction with another.

always scan thumb drives as well. when I was in the navy I remember when we could use them no problem, then a few years ago they said no more, due to a propagating virus that could easily find its way to a thumb drive then start spreading once plugged in.


last but not least IF in the event of the need of a reformat. do it right ESPECIALLY if you are not sure of the virus' whereabouts/details

that is, complete reformat then CLEAN install perhaps get a disk, or fresh download. from a reputable place, nothing like using a compromised install.

ALWAYS forget about all other stuff, and if absolutely unable to separate from the pictures or files etc. safe to a back up area and thoroughly scan the documents, try to refrain from backing up programs, as those tend to be more likely to be infected. just re download / install them.



although HIGHLY unlikely, there are actually some top level virus' that are actually capable of surviving a reformat, that along with data security is why the military randomly overwrite hard drives over 7 times to insure that all data is lost, (hence why o you think file deletes are so quick, and even formatting, all it is doing is deleting the allocated space / tables, only they way to actually delete a program is to overwrite that portion (ie change the magnetic propertied)

some forensic programs can recover data overwritten several times over. so use a good program that will overright the data several times, in fact there are "trash bin" programs that do just that to the stuff you delete / place in the incinerator as they are called lol.

I am aware of Anti-virus limitations.

I also think you need to be cautious with the programs and files that you run/keep. That's why I always used free AV solutions, because I tought being careful was all I needed. This is the first time in years my PC got infected, and as you see above was a really ugly infection.

As much as I'm cautious, I can't control how cautious other people are. This PC gets used by several people. Actually, the infection I found on my backup wasn't located in my user.


I've bought Norton 360 and I've been spending the last hours configuring it. It really is more much polished than free alternatives.

and as you said you cannot control others, THAT is also why you need a better A/V program lol.

and the ease of use / features also adds to the piece of mind. not to mention the free alternatives don't have an incentive as much for continuous process improvement

the paid services do since they charge, they make sure their stuff can detect the latest

also hours?

why so long? is a fresh OS install / setup? usually you wont have any issues, programs that are supposed to be easy to install when they are not you know you have an underlying problem

if its an old setup especially one with a virus that could cause issues. perhaps the virus may be making it hard to install (i am not sure if thats a thing though)

the firewall portion may be needed but I usually never have issues.

What I mean is I like to read what every major and minor feature does. Though, I barely had to change anything, the default config. is good for me.

Is not like I spent 6 hours lol. I just like to read rolleyes.gif

the sad thing of the matter is, Norton doesn't hardly protect you from anything. I work for a pc shop as a tech as well as for a major st Louis Missouri company as a pc tech, and I cant tell you the amount of times ive cleaned 1000s of infections off a system "protected" by Norton. a paid antivirus like Norton does you no good if your just doing silly things on the net anyway. plus its a proven fact Norton is harder on system resources and since I know it doesn't protect me from squat ill stick with avast free.
