To add further.There is a tell tale sign that you may have scripts running in the background on your pc. If your pc is working slower and even real slow at times. If you hit ctrl/alt/delete and find not much running and then right click on "my computer" icon and choose properties/ and then click the performance tab. if it says your system resources are lower than they should be and not much running. You could have scripts running. Some people get so many the pc crawls and stalls. My buddy did not take my advice but came back to ask me where to get adaware cuz he ran at less than 46% resources at times. Restart and recheck resources again. This should be above 90 % this time and not mean for sure you need adaware cuz you have them. You then have to open and reclose a few programs you usually and/or just been using. Some programs do not give back all the resources the used when you first opened them. And do or do not take away more each time you reopen and close it. I keep my ctrl/alt/delete window with only 5 things in there and I know what they all are. I also like this because if my pc is grinding having just 48 ram, I hit ctrl/alt+delete so see if there is a 6th one. find the stranger and end task on it. I know what I need to run this. Every install should include a check for it in the ctrl/alt/delete and kept or dumped out of start up or just kept track of as #6. I never had a fire wall, and never been hacked yet. I end task on anything odd, and keep right on a surfin. One has to be very careful and notice if the pc is working extra hard! Harder to tell that by ear if you have 256 or 512 ram, with a fast processer. I could go on and on but, I will wait to see if someone deputes this much. One thing is I do not recommend anything I haven't use for months and Know to be good, with no bugs to hurt your pc. Adaware is the only thing out there anywhere that can find these scripts. You can not find them any other way! period. It is also the only way to clean them out. You can't delete what does not show up in any folder of your pc. Maybe in dos mode, who knows. but me and a few friends were sure glad we used it is all! I know for a fact that someone will come back to this post and say they had a bunch of invisible stuff running and cleaned them all out. I had one friend who only had to start pc and click on anything and more than 10 ads popped up and kept reopening. right off his desk-top. But that was because he was so infected with ads, I found out that his step-son was on the pc a lot on adult sites. He had it bad on his pc. He ran adaware and not one thing was wrong after. I heard he just ran it again.! HA Ha darn that kid.
