virus unidentified by avira or avg

when i opened my thumb drive today (which was previously plugged in my friends computer). i scanned it using avg and avira antivir (both installed in my system). no detections were shown. however the drive contained a hidden file called "ouehbs.exe". (i have hidden and OS files visible) i scanned it again using avg and still didnt find any virus. so out of curiosity i double clicked it and it opened another windows with the same contents (i.e location of the usb drive J .

i closed it and went to C: to see that the hidden files are again hidden. so i went into folder options and changed it and i thought it was over . however on next restart i again found my hidden files going hidden again. i donno how the antiviruses didnt detect this malice program. does anyone of u have any experience with this. googling with the exe name didnt help. pls help to sort me out this problem

 

I don't know why you would ever consider opening an executable that you don't know the origin of...
BUT.
Yes, this is totally possible. Virus definitions need to be updated before they can detect things.

Also, having two anti-virus programs installed on one system is VERY BAD! Causes huuuuge system slowdowns, since an AV monitors everything going on in the system constantly, the two just monitor each other. Uninstall AVG, it's more or less useless compared to Avira anyway.

Do any online scan with http://www.bitdefender.com/
Download HiJack This! and run it, and post your log here.
You may also want to run a SUPER antispyware and a MalwareBytes anti-malware scan.

 

i would also suggest spybot search & destroy

 

malwarebytes is the best imo with any kind of malware of spyware

also try smitfraudfix

 

thank you for your replies....... i had the latest antivirus updates for both softwares at the time of attack. my college lan is so clogged up with viruses that you cant survive without two antivirus. can u recommend me an antivirus combination that would just work fine and catch all virus

 

Again, MORE THAN ONE ANTI VIRUS IS VERY BAD.
Uninstall one, the system's speed will increase dramatically!
Avira is enough, AVG is not offering you anything additional.

And again, definitions, though you may have the latest, do not necessarily have the files in question added to them yet.

Use Avira and Spyware Blaster for protection. DO NOT install more than one AV.

 

Hi.

You can upload any suspicius file or files to the free site below and it will be checked with 15-20 different virus checkers and you will receive a report.

No it's not. Having two anti-virus programs with both of their active protection ON is bad. Having one anti-virus program with their active protection ON and the other OFF, is completely safe and fine. The only other consideration one must take is to not run two anti-virus scans at the same time. Similarly, you don't want to run two anti-spyware scans simultaneously.



My suggestion is to run Avira with its active protection ON and Avast with its active protection OFF. In fact, you can even select to not install Avast's active protection which is what you should do.

 

yEp. 2 AV's=BAD. Mine was much worse in my XP computer.. iteven removed the folder options tab to make thing visible or not. Avira is a good bet, very reliable. Can have false detections, but in a good way. Avira Ftw.

I hope you followed these advices from these elite people above. They knew much more than we noobs do.

 

Some will even have issues with active protection turned off because of some of their background services. Just an FYI for the future.

 

Well Avira and Avast play nicely together. The ONLY two things Avast has running in the background from time to time is to update its virus definitions and build its VRDB. Again, conflicts really only happen when both have their active protection ON. I haven't come across a combo of Avira, Avast, and AVG 7.5 where running one program with its active protection uninstalled and the other ON, created any conflicts. Nor have I heard of any conflicts in that scenario. Now, I have heard of plenty of problems when both anti-virus programs have their active protection ON.

 

Bitdefender does not play nice with Computer Associates eTrust, even with eTrust's active protection turned off. I have personally witnessed and confirmed this.

 

hmmm maybe all of us should compile a list of programs that do and do not work well together along with basic steps to take to remove virus/spyware/etc. Either that or add to one of the current sticky threads. We're constantly getting how to remove virus questions, so a sticky in this area should be helpful, especially if it's titled, "How to Remove Viruses."

 

hmmm thanx for the advice guys. i have decided to keep just one AV. but instead of removing AVG and sticking to avira is it safe to remove avira and go on with AVG as i see that AVG free edition has got built in atispyware, but avira free doesnt have one.

and inorder to solve the problem, i reformatted and reinstalled vista. now everything is working fine. however i still have two antivirus AVG (free) and NOD32 (trial). i think i will get rid of NOD32 and continue with AVG

 

What part of not having two AV's is so hard to understand? Personally, I'd use Avira or Avast and SuperAntiSpyware or Malwarebytes Antimalware.

 

I use a combination of avira and spybot search and destroy. Works well enough I suppose, however I find the teatimer for spybot to be pretty bloated.

 

Good combo, just don't install TeaTimer or SDHelper.
