Almost a week now, trojans keep on attacking my comp everytime i online. There were more or less 100 attack in only 3 days and i only online about 10hours average everyday.

ha? are you sure? 100 trojans a day....
wow... that's breakin my record (45 trojans a day)...
i think you should take a deep breath....
disconnect your internet...
scan your computer...
and reconnect...
if your resident shield is still detecting any viruses after reconnecting....
you should check, whether your browser is infected or not....
cause some trojans infect the browser and force it to download viruses (but man... 100? are you sure?)....
this one quite troubling, cause i don't know where the virus's nest in your browser (the location is vary, depend on your type of browser and the type of virus itself...)
i will keep researching about that....

BTW... are you Indonesian?

you have misread my post. 100 attacks in 3days, you still hold the record. =|

i have scanned the whole comp 3 times, no virus whatsoever, at least none can be detected. but the attack still occur. that is what scares me. lately when the attack happen i will disconnect my internet.

the trojan usually attack temporary internet folder and system32 in my windows.
should i get a new antivirus software?

p/s: i'm malaysian

It sounds like whatever initially attacked your comp first left a backdoor, so now all these viruses are getting in easily.

Only thing I can suggest is getting a new anti-virus software, as well as an anti-spamware software such as spybot or adaware. It might be a case that some of those programs being detected are just spyware. It's happened to me once or twice so you never know.

Here's a thread or two that might help you chose software:
What anti-spyware are u using?
wat anti virus do u using?
KILL VIRUSES and MALWARE... dangit..

it's best to install all the security updates on the microsoft windows update site (that is, if you're on windows)
(such frequent attacks are likely to come from a computer on your local area network - or more than one, corrupted as hell)
the security updates and the kaspersky internet security suite (KIS) - which i suggest you install, it's a different thing altogether than the KAV - these would provide enough protection

i try to install antispamware software, and i just remember after i read deepflow post.
a few weeks, 2 or 3 week before the attack occur i change my KIS 6.0 to KAV 7.0.

well for now we'll see what happen. thanks guys.
any more opinions are certainly welcome.

Being attacked by a virus is different from actually getting one. Yes, there are viruses and stuff that will relentlessly attack your PC when you log on, but most -- if not all -- of those viruses are now included in most antivirus programs' protection list.

I think that, with some programs, you can tag "do not mention again" for each virus attack from a specific virus. As long as the antivirus software is active, there's no need to be notified each and every time some virus TRIES to attack your PC and fails.

If this is an actual infection, however.... just ignore what I said. It's my experience that the really dangerous viruses aren't ones that make random attacks on your IP.

Get yourself some anti-malware, anti-rootkit and a firewall while you are at it.

Wow! My computer has only been attatcked by a trojan once!
What sites are you visting?
To prevent it, try clearing of the 'COOKIES' in your system!
also, it may be a bother but try buying a anti-virus protection kit!

This 'KIS 0.7', is it freeware? freeware types you have to teach it to repond!

Here's my opinion...
1. DISCONNECT from the internet.
2. BACKUP all important documents.
3. Do a FORMAT. (LOW LEVEL)
4. DO A CLEAN INSTALL OF your preferred OS.
5. INSTALL FIREWALL, ANTI-VIRUS, ANTI-SPYWARE.

TROJANS are sick bastards, they will not only ruin your software but also your hardware... you better act fast!

that exactly what i'm afraid of "format comp". Well now i'm still in trial period with all new antivirus antispyware installed.

things are better than before but not as good as i expected. *sigh~*

I've been having virus problems too lately
I tried downloading Ad-aware, avast, avira and they were all crap
They only detected viruses and just made my computer lag like a traffic jam
I installed Norton and it got rid of quite a few viruses over the period of 3 days and my computer isnt back to it's full functions but it recovered somewhat

Always use an internet security suite, as it includes a firewall and antispyware/malware.

You can get an excellent free anti-spyware/malware program called spybot on the net. The programs is free (but all donations are very welcome) and comes with regular updates. But remember to use this inconjuction with anti-virus protection, as it is not a replacement.

I do NOT personally recommend Norton antivirus in any shape or form. If you need to buy a new internet security suite check reviews on the internet or ask people you know what they use and if they would recommend it.

Don't use your anti-virus software to check your computer again, obviously the program has been compromised (it's on your computer) or it can't do anything about it. If you know your trojan's name(s) look for information on the net (google works fine) but remember to include either 'information', 'removal' or insert your own request after the name, who knows what you'd get if you didn't.

If all else fails I used McAfee Stinger (with system restore off and in safemode) to knock my worm and trojan out of existance -knock on wood.

Good luck!

Trojans are usually not so dangerous, but they are a pest. BUT IF YOU USUALLY BUY THROUG INTERNET, YOU NEED TO UPDATE EVERYDAY YOUR COMPUTER

1.- You need a powerful antivirus AND antispyware. For my computers I use Norton.

2.- ACTIVATE YOUR FIREWALL. Some programs and sites in internet, in order to work, need you to disarm your defenses. AFTER USING THEM, REMEMBER TO ABLE YOUR FIREWALL AGAIN.

3.- If the problem persist, maybe you'll need to take your computer to the technichian IN ORDER TO MAKE A DEEP CLEANSING -READ: FORMAT YOUR HARDISCK AND INSTALLATE AGAIN YOUR PROGRAMS, AND FOR THIS YOU'LL NEED TO BACKUP YOUR DOCUMENTS AND OTHER STUFF IN CD's OR DVD's- Deep cleansing is different to a normal format, but you have to ask the thechnichian.

4.- LOCATE WHERE YOU HAVE BEEN THAT COULD HAVE DOWNLOADED THE TROJANS.

I only use McAffee, it doesn't so bad. But when I got trojan or any worm that McAffee can't delete or detect, i have a ultimate weapon... #PC-MAV# Antivirus. I never seen antivirus like this, it's have small size so it's portable. I got this from PC-Media magazie. It has Realtime Protector too and I heard that PC-MAV's database can be fuse with ClamAV antivirus. Well, since I use this combo (McAfee active (realtime) and PC-MAV passive (disabled) there's no virus infect my computer between march 2007 to now. (The Important thing is you always UP TO DATE). But, this PC-MAV only distributed in Indonesian..

when i check the log of the attacks. most of the attack came from this particular website. i dont remember ever visited that site though.

i still want to consider using combofix

well i think you can scan all your system with your antivirus, of course it need to be updated to know the new virus. After that you can remove all your virus with your antivirus.
