Worm/Autoit.YGN

Post by HannesM on 25th March 2009, 12:29 am

Hello

Today AVG gave me a warning, it said that it hade found a Worm/autoit.YGN. So I checked the AVG "virus database" to see what I could do about this problem. It told me that it was safe to delete the file, which I did. So far so good, after I had deleted the file I started a complete system scan, with AVG, but it did not find any infections. However, some hours later AVG gave me a new warning that it had found another Worm/autoit.YGN (it showed up after I had restarted my computer), so I deleted it again. And after all this I started another system scan, and AVG did not find anything during this system scan either. Can I trust that AVG has "totally deleted" it this time?

About an hour ago I downloaded SUPERAntiSpyware to see if this program would find any viruses, it did not however.

My question is: Is my computer infected by anything? Is my computer still infected by the worm or anything else? If it is, should not the anti-virus programs be able to find it during the system scans? Since I am not sure about all this, I thought I that I would check the problem here.

Btw, I know that you should not run two anti-virus programs. I will remove one of them once the problem (if I have one) is known. And, do you have any other recommendations of free anti-virus programs, that are better?

Ohh, almost forgot, AVG virus log: Virus identified worm/Autoit.YGN - Object: C:\System Volume Information\_restore{619781AC-CF96-4B2F-8E58-2353903809FC}\RP308\A0056079.exe

I noticed that a running process I have called "crss.exe" was not added in the log I presented. But maybe it should not be included since I tried to make a new logfile, but it did not show up there either... well well.

Hello.
Just take note that autoIT doesn't mean a virus, it means the executable has been packed in UPX and this sets off a lot of antimalware scanners, which maybe a false positive.

Anyhow, System Volume Information is just system restore points, so flush them by doing this.

To turn off System Restore, follow these steps:
1. Click Start, right-click My Computer, and then click Properties.
2. Click the System Restore tab.
3. Click the Turn off System Restore check box (or the Turn off System Restore on all drives check box), and then click OK.
4. Click Yes when you receive the prompt to the turn off System Restore.

Now we need to make a new restore point.
To turn on System Restore, follow these steps:
1. Click Start, right-click My Computer, and then click Properties.
2. Click the System Restore tab.
3. Click the Turn off System Restore check box (To turn on System Restore), and then click OK.

Hello again!

I followed your instructions and flushed the system restore points (I also received 4 gb more space on my hdd because of this Big Grin). After that I scanned the computer after infections with AVG. The program did not find any infections, and evrything seems to be perfect (for the moment at least Goofy).

Thanks a lot for your help, and quick reply!

Just one more question. I currently use AVG, do you know any other free anti-virus program which is better?

Thanks again.
