Viruses-Unidentified?

Hello. My recent virus scanner PC Tools AntiVirus showed up 5 new viruses on the computer. I searched Symantec and Norton's website but I did not show anything. Can you tell me what these viruses are, how you get them, and what they do? Long, to the point responses wanted. No short ones that include "just google it or something." This will take some serious researching but if you have the effort, I will choose you.

Here are the viruses:

virus: JS.Trojan.DL.A

virus: JS.Trojan.DL.A

virus: Win32.Cholera.B

virus: Win32.Cholera.B

virus: Win32.Cholera.B

Also is there a real time scanning anti virus that does not lag your computer? Something like Norton but you don't have to pay. Thanks.

The answer to your question will differ from person to person as they will tell you that the one they use is the best, but that is there personal preference.

From my experience , antivirus and anti spy ware is only as good as its data base, it does not matter, which one it is, if it has not got the virus in its data base then it will not pick up that particular virus,

There are thousands of wild viruses out there; your guess to how many is as good as mine. So I think in picking any antivirus and antispyware, is down to personal choice and which one you are happy with.
