Seriously, has anybody ever seen a serious virus problem in Windows when using AV protection?

This was an office of one of the world's largest outsourcing companies, well protected by commercial AV systems. It took the IT staff a few hours to clean up the mess.

Yes I have, *many* *many* times! There is nothing rare about a machine running up-to-date free or commercial anti-virus software and still be fully compromised, usually with several species of serious malware (e.g. root kits, key loggers, spam bots, ransom ware, egold stealer). Fully updated anti-virus software like Avast, AVG, Kapersky, f-prot, Norton, etc, are by no means a guarantee of safety against malware. > One of the claims of the Linux crowd is that such problems are > legion.

You certainly are not. >BTW, check out this PDF on AV software: >http://www.av->comparatives.org/images/stories/test/ondret/avc_report22.pdf > >It compares 16 commercial programs, and finds Microsoft at #2, >catching 60% of all viruses (Avanti is #1 at 70%). If the number one anti-virus catches *only* 70% of all viruses, then it lets 30% of them pass. That is just proof of failure, not success and definitely not a rare occurrence. >And we're taking about all viruses, some of which as so obscure I'm sure >you'll never seen one in the wild... The real problem are the new viruses, obviously, not known by the anti-virus programs. The heuristics used by the anti-virus are also of little use to detect new viruses since any capable virus developer can test his creation against a good number of anti-virus and tweak the binary until it is not detected.

A good question, but perhaps you are asking the wrong people? Would it be better (just as an example) to address your question to Manchester City Council or to the Greater Manchester Police? http://news.bbc.co.uk/1/hi/england/manchester/8492669.stm It is of course quite possible that the administrators were not so knowledgable as yourself, and would therefore benefit from your advice. Judging by the cost of outbreaks like these, I'm sure you could make a lot of money - the cost seems to work out at about £1,000,000 a time to clean up the mess. Go for it :-)

But talking so some of the people at alt.comp.anti-virus I > get the impression such problems are rare. I was running AVG ver. 8 and got some malware that hogged all the CPU time. It caused operation to slow so much that I couldn't run the computer and had to transfer the HD to a computer with a dual core CPU. A full scan with AVG indicated the problem but couldn't fix it. Norton detected nothing, and free online scans by Trend and PC Pit Stop didn't fix it (I don't remember if they detected it), but Bit Defender partially did, and the rest of the problem was solve with either ComboFix or SmithFraudFix. |
