Vista - Antivirus with a virus infection?

I'm posting this for future reference which might be helpful.
I downloaded "SuperAntiSpyware", it helped but did not solve the previous problem (persistent virus alert).
So i tried downloading Kaspersky security. But it has to remove my existing antivirus software- Avira.
Fortunately, this procedure stopped the frequent virus alert.
It was only then that I realized the FAKE virus alert was caused by Avira.
Technically, I don't know how to explain such case so if somebody has the explanation, it will be highly appreciated.

False positive Virus alerts can happen with any antivirus program if you receive a virus alert for a program that you believe to be safe i would recommend running a test on the file with an on-line scanning site I personally use VirusTotal - Free Online Virus and Malware Scan but others are available.

the important thing is to provide feedback to the manufacturer of the anti-virus giving the false positive so that they can act on it. this way the product will improve

If I am right in thinking your Avira anti-virus is now replaced by Kaspersky, then. Virus recognition is not 100% foolproof which means that a legitimate Anti-virus programe may see a legitimate piece of codeing as a virus ie a false posative or fail to recognize a Virus ie a false negative. With this in mind, it is usefull to have one mainstream anti-virus application that runs 24/7 and others which are only run on demand types . In theory it would be good to have two or more anti-Virus applications which run 24/7 but the problem is that they are likely to cause conflicts with one another. The problem is that Avira may have actually detected a Virus or some other sort of malware that Kaspersky is missing, I am not saying this is actually the case but it is a possability. Bye the way did you try the quarantine facility in Avira before you got around to downloading Kaspersky.

PS It might be an idea to fill up your "My System Specs" box at this site, with a bit more information as that would make it easier for people to help you. For start you could add 32 or 64 to Your Vista details as this operating system comes in both 32 & 64 bit versions.

hey just scan your computer with Malware- Bytes anti malware.
download it from here: http://www.gur.in/j/index.php?option...ownload&gid=97

or you can try Hijack This to determine the faulty software. Download link:

Personally, I do not recommend running more than one antivirus program on the same system. They can conflict with each other. One might detect the scanning activities of the other, find it suspicious, and cause you to think there is a problem when the only problem is that you're running two antivirus apps simultaneously.

I've had good luck with BitDefender on single-machines. I don't recall ever having used AntiVir.

If you have a suspicious file, you might try running it through VirusTotal - Free Online Virus and Malware Scan

VirusTotal.com is a very handy website that will scan individual files with 36 different antivirus scanners. It's not a solution for protecting your computer, but if you suspect that a single file may be infected, it is an invaluable tool.

First try & run a free online virus scan. Then check if it states as the system is infected or not. If yes then remove that infection using the anti-virus you have currently installed on the system. And then for safety you can also run software's such as hijack this, super anti spyware, or malware bytes to remove any traces of infections.
