hotmail told me a file was virus free....they were wrong....what can i do?

I got a hotmail message and for the first time ever, their virus detection system failed. It told me there was no virus detected but it had one and it happened quick because I was not expecting it since hotmail told me it was not detected. It is located in documents/temp. and was some sort of "worm". It told me to open my AVG to locate and remove it. But, AVG did not find it. I do not know the precise location of this virus. What I gave above was what I quickly saw. I remember seeing the word temp or temporary. While AVG was running a scan, I went to control panel, internet options and deleted the cache.
Would this alone have removed the virus?
why did hotmail miss it?
why does AVG not find it?
how can I find it?

Do not EVER count on any single antivirus detection system to catch everything. Especially from a free mail system. At least that is my opinion. However, not to just be critical I do offer a suggestion. Go to the TrendMicro Systems link I have included and it will scan your system with "their" latest virus pattern file. If the virus at hand has been dealt with by their folks, then it should detect it. You can also research on that site as well. Hope it helps.

Well HMail do state that theie virus scans are not perfect and hold no responsibility for you getting infected.  If you are, then get something like symantec or sophos anti-virus with latest patches and try them with it.  If it has installed itself then clearing the internet cache will not help you.

AVG may not detected all the virus. I as thinks, NAV may be the best anti-virus program. You can download one of Norton Antivirus Version and update newest virus definition, run and try to detect.

I dont know exactly where to download trial version of NAV2005 but you can search it through the

also... seeing how it went to a temp folder supposedly.  If it were my machine i'd just do a search for Temp and clear out all the temp folders that i Had.  Then if that is where it was located, i'd be sure to get it.  Housecall is a good suggestion... i use it often, Along with Ad-aware and Spysweeper (for Ads and Spyware).

Use AVG and TrendMicro. I personally use AVG and get the frequent updates for it.  Some say Norton is better, others say AVG.  I used Norton and didn't like it, but it's just my view/opinion.  It's best to use this with TrendMicro since they probably have a last minute up-to-date definition files there.

If you have XP or other versions which has multiple accounts, clearing the Temp folder can be tedious.  I recommend using a free program to do the job easier.

The Temp folders should be cleaned out periodically as installation programs and hijack programs leave a lot of junk there.  Download Index.dat Suite ( to clean out all the temp folders.

Run Index.dat Suite now and go to Tools->Settings.  Then make sure to check the following: Cookies, History, Recent Documents, Swap File (if you have Windows 95/98), Temporary Internet Files and Temp Files.  Click Save at the bottom.  Then click on the Find button.  Let it search.  Then click on the second button on the top.  This will generate a batch file.  Click Next->Next->Next and it will tell you that after the next reboot/restart you the file should run by itself and startup and clean all those files.  You can also go into My Computer->C: Drive and double click on the run.bat file to clean up all the temp files.

Hope that helps.
First, how did you find that you have a virus?

From what you are saying, you may not have any virus at all.

I sometimes wonder if people even read the previous suggestions before saying the exact same thing with nothing new.

I had a file attatched to a hotmail message. It told me "no virus found". so I opened it. Upon openig it my system notified me of the virus and its location. It said "use you AVG" to remove the virus, but AVG did not find it. All, I did was delete temp files as it seemed that was the file/folder/location where the virus went. So, I assume it is still on my system somewhere.

I'll try all the above solutions.

here is what housecall found:
5 infected files in C:documents
all were non cleanable
three had java bytever.a
one had joke winavoid.a
and one had joke geschenk.a
they were deleted
can anyone tell me what kind of virus's they were?
 java and joke are the key words.

From, the same place as the housecall application, you can research the viruses by name.
Glad the suggestion worked.
If housecall doesnt allow you to delete them with it's delete key (which the java one probably wont...dont know about the other).  Then you should try going directly to the location of the file and select it..then do a Shift-Delete (bypassing the trash bin).  If that doesnt allow you to delete it that way, you might have to either go through dos prompt and delete it, or boot into safe mode and delete it.  Be sure to write down exact locations of the documents.

- The JAVA (Bytever.a) is a javascript malware that affects Internet Explorer:

This malware is a component of a malicious Java archive file (JAR) that resides in a malicious Web site. Machines infected with the malware JS_FORTNIGHT.B are redirected to this Web site.

This malware calls and executes another malware, JAVA_JJBLACK.C, which results in modifications to the browser and registry settings of the infected system.

This is TREND MICRO's detection for JAVA classes that exploit a known vulnerability in Microsoft Virtual Machine in Windows Operating Systems and Internet Explorer. This flaw allows malicious users to execute codes of his or her choice when a user visits an infected Web site.

- The JOKE ones are only jokes like a little funny program that you can close because the close button is getting away from your mouse pointer, etc. "It is not a virus and is therefore, not a threat to a system."
