YMMV One of a multitude of acronyms floating through this plane of existence....
For those not knowing what it means....
Your mileage may vary...YMMV
A handy catch-all term highly apropriate to those electronic brain machines we use so much nowadays.
What works mighty fine on one computer may not do as well on another. Not surprising, buckaroos and buckarettes, considering the multitude of variables... differing operating systems, different softwares installed, a multitude of variables!!!
In my case, SpySweeper works fine. It does take about 15 seconds longer to open than my typical software but once it's up and running it does what it should do.
I also use AdAware. They do not interfere with each other but I run them separately, closing the one before opening the other one.
I seldom have SpySweeper running in the background to inform me of browser hijack attempts, etc.
I simply do not have a problem with malware, spyware, etc. I probably do not need the two programs but, for safety's sake, they are present and are run every week or so.
One reason the bad/hostile coding doesn't enter my computer is that active scripting is on ONLY when absolutely needed for a Web site to function properly and I engage it only when I trust that Web site.
Active X is used perhaps once or twice per year and that is only with reputable sites. Basically, I shun/boycott 99.9 percent (or more) of sites requiring Active X.
The above two tactics greatly decrease the likelihood of hostile code creeping in.
Other well-known tactics are having e-mail set to text only, no HTML view. Never open attachments unless 100 percent sure they are safe. All programs entering my machine are carefully scrutinized. Even legitimate programs can hold embedded spyware or malware.
There are many various tactics that can be ascertained via bountiful browsing of the MANY sites offering extremely ueful info about "safe surfing."
Wilders.org is one of many good sites and their message board is nifty.
Educate thineself and become one of the apparent few who can go through life well-lubricated and free from hostile coding.
