Virus Chest - System Files

??? I am new to AVAST but plan to be a long time user. I really like it. I also had a friend install AVAST on her lap top and helped her to get started. She had several occurrences of a worm and AVAST found all 103 of them and I was able to remove them. ;D
She also had a virus regarding HOTBAR and AVAST found them and I moved them to the CHEST. After several scans and the use of Spybot Search and Destroy the virus is gone. However, when I look in the CHEST under System Files, I found the following:
Kernel32.dll Winsock.dll and Wsock32.dll (all in Windows System32)

Herlaptop seems to be working fine and free of all viruses and worms. My question is should I do anything with or to the three dll’s or just leave well enough alone?
Any help is appreciated. Thanks

The answer is in your question.

However, when I look in the CHEST under System Files, I found the following:
Look at the EXACT location they are. They are under the SYSTEM FILES. Those are just backups from a few system files, that Avast can use in case the original ones get infected.

Look at this board as a huge book with questions and answers.

Thank you for the info and I will try to remember to use the search function in the future. I got a lot of info from this forum yesterday when I was trying to rid all the viruses and worms from my friend’s computer. Thanks again.

Welcome to the Avast family !

Thanks for the welcome message. In the past, I have used Norton, McAffee and AVG. (I have a 2 year subscription for AVG on my desk top now) and finally a friend told me about AVAST so I installed that on my laptop and love it. I will more than likely switch to AVAST on the Desk top as well. Yesterday, I became a bit more involved with the AVAST anti virus product and now I am a firm believer in the product. I will spread the word to other friends.
