A few years ago, my computer started to slow down and I was having problems installing a virus-checker. I talked to technicians who worked with the virus-checking program. They told me that my computer was being slowed down by spybots. They suggested that I install Ad-Aware and scan. They assured me that this program would get all the spybots infesting my system. They were right.
Anyway, two weeks ago, I upgraded Ad-Aware to the 2009 version. It is still free, but there are more additions to the program and it works better. I had been attacked by another virus, which I was able to catch and remove before it got on my system. However, it made me nervous that my system might have other problems.
After updating Ad-Aware, I scanned my computer. I found two malware in my computer. The Ad-Aware removed it without any problems. Now, I clean this computer daily. I virus scan this computer two times a month. So it was quite a shock to find the malware.
But, once again I am grateful for this program. After removing the malware, my computer worked better --again. So I use this software for scanning my computer, daily. So if you are having problems with spybots and malware, I suggest that you go to the lavasoft site and download this program. It works well.
