Through the past months, it has become really infested. And its getting worse!!
If your going to use it, the best thing you can do (imo) is look for the file's that are capitalized, with the artist in front of the title.
e.g..Bob Seger-Against the Wind(MP3)
Corrupt file...aginst the wind-bob seger
Today, theres even a few, that look safe, but arent. I suggest you do your searches several at a time. Then run a full system scan, opposed to a few on several different occasions.
The last time I installed, Limewire I didnt get infected. But after I installed the Java, I did.
Live 1 care, has great real time protection for this.
