I do not understand how they can be Re-installed, unless you plan to Re-infect the computer yourself ?????

 

Do you always visit sites that you know will infect your computer ?? If not Delete them. now -

I'm pretty sure he just ment that if they where necessary to run something, he'd just reinstall that something.

 

Either way, quarantine basically saves the file on your AV's Vault just in case it was a vital file AND a false positive and you can get it back, while delete simply deletes the file, what you do is up to you.

It's safe practice to Quarantine, rather than Delete when files are suspected to be infected or malicious. In the quarantine chest, these won't reinstall themselves, and after a few days or weeks can be safely deleted if not needed. Be double sure before total deletion, as there could be a seldom used app or service that needs the file(s) in the chest.

 

Certain files such as Open Candy software can & should be deleted, no point in keeping this type of file (adware/PUP) on the computer. MBAM picks up on these type of files on Hyper (short) scans & normally a reboot will be needed for complete removal.

I've never kept any quarantined item...and I've never had cause to regret it.

 

How can a file that is either severely damaged or not right for the system...have any possible redeeming value?  If it's a system file, a clean copy is preferred over an infected or damaged one.  If it's not a system file and it's safe...then you need to ask yourself why it was quarantined.

 

Even if it were a false positive...any good file is easily reinstalled/replaced.

 

I understand the logic of the premise...I just think it's faulty reasoning because the premise is invalid.

Louis, I agree with you 100% with your view on this.  :thumbup2:

 

And on my own computers, I delete w/out hesitation. However I perform maintenance on other's computers & in the instances where there's no time to perform an image before repair (my preferred method), choose Quarantine as a safe default. Later on, the next time I get to them, I image the drive, empty these quarantine folders, run virus/malware scans & extended disk cleanup & if all is OK, re-image again & delete the prior one. 

 

If I'm busy & have just a few minutes to drop by for diagnosis/repair, or calling to walkthrough, I feel it's safer & that's the only time I'll save quarantined files. In an instance such as this, it's usually urgent & I don't have time to fiddle with an unbootable computer. Sometimes these calls may come in at 11PM-2AM, I'm not getting out that late to perform a computer repair, it's normally the time when I participate here or at another forum unrelated to computing.

Doesn't hurt to leave them there for a while though, to be sure. They normally get a name change with a .vir extension and become inactive without manual manipulation.

 

The chances are that if your anti-virus found 10 items there is more on your system. Your antivirus alone cannot remove most infections, it is more of a protection mechanism than a removal tool. You should start a removal topic OP.

Hello linked_up,

 

Your question could be answered more easily if we knew which files were found by the scan.   Can you please post the log for us?  I'm transferring this topic to the Am I Infected forum.

Just based my reply on this question as written.

It said Malware Scan produced several (I assume infected items) files.

 

As per Orange Blossom, please tell us the scan that was done and the result, if you have any logs -
