how little is a virus?
462681
A virus particle, known as a virion, is little more than a gene transporter, consisting at the most basic level of a genome contained within a protective casing of protein.These structures can range in size from less than 20 nanometers up to 400 nanometers. you need an electron microscope to see them, and in many cases you can only see their shadow, or figure.Remember that viruses cannot reproduce on their own.Viruses are non-living particles and can only replicate when an organism reproduces the viral RNA or DNA. Viruses are considered non-living by the majority of virologists because they do not meet all the criteria of the generally accepted definition of life.

Non-living\n\nA virus is a submicroscopic obligatory parasitic particle that infects cells in biological organisms. Viruses are "non-living particles" that can only replicate when an organism reproduces the virulent RNA or DNA.

*BZZZTT* and your ALL out!  That's incorrect.  \n\nViruses are NOT inherently evil.  They are just programs that work viraly.  They may self replicate, although that sort of goes into the worm catagory.  I'm assuming your talking about malicous computer viruses.  And judging by your earlier post "How do I become a hacker" I'm guessing you want to impress everyone and write a virus.  It'll never happen.\nGo home!

When it comes to computers, there are only a few stupid questions; this is not one of them.\n\nUnless your computer overheats (a rare occurence these days), you're fine.  You can scan for viruses all day & night if you want to, and if your computer can handle it.\n\nImmediately scanning everything you download is perfectly OK; I do that myself.\n\nAlso, as a side note, if you want to scan for viruses on your entire computer, you only really need to do that about once a week at most.

It isn't cleaned or removed because it isn't a virus. It's a system file, an index of the files in that folder, like a table of contents for the computer to read.

almost do have virus in it, but this is what you do, just download it first without running it, then use your antivirus to scan it before running it.

The worst case virus I think was CIH/Chernobyl. This could destroy the BIOS on some machines, which means you couldn't even format and reinstall.

It depends on the person, and the strength their immune system, but also the strength of the virus. I would assume 10 days is a little bit longer than the average, just so that people do not spread the virus.

theyre still contagouis  there are tiny viruses that are still there

Antivirus programs are far from perfect. They're known for misidentifying files as viruses.

the virus likes to mutate. so even if they did have one.. it wouldn't work for very long

those things are just slightly more popular than viruses\nluckily, they are easy to disable

It can be either (a) or (b) or (d). This depends on how the strong the cell is or how conducive is that cell for that virus. (e) is not possible because virus and bacteria are two different organisms. Virus is much more smaller than bacteria.

In addition to Hybrid's answer:\n\nDepending on the severity/quantity of viruses, you may want to look into:\n\n1) If you have an anti-virus program, run a full scan on your system. Look for McAffee or Norton antivirus tools in "programs" for starters.\n\n2) If you have no antivirus program installed, try AVG free addition. It is easy to install and you'll receive regular updates to counter new virus attacks. You can also use tools to run full scans on your system. You can download it at: http://free.grisoft.com/doc/2/lng/us/tpl...\n\nOr, try the following link:\nhttp://housecall.trendmicro.com/...\n\n3) If a PC is plagued with viruses, your best bet is to clean the system BEFORE it boots. This can be done by using some free tools available. Check out:\n\nhttp://www.nu2.nu/pebuilder/intro/...\n\nYou use PE Builder to make a bootable CDROM that loads a windows-like interface in memory. Because none of your hard drive files are locked they can be cleaned of any viruses. BartPE provides free McAffee plugins that you can run to accomplish this. WARNING: you have to fairly computer savy to work with BartPE. You may want to recruit a friend to help. It's more work, but I've found this to be the most effective way to clean your system.\n\nHTH,\nD

I'd not worry about which are and which aren't (infected)...I'd run a virus program that scans, cleans, disinfects and deletes infected files on ALL computers.  That way you have no worries about trying to figure out which ones are, or aren't, and cover all the bases in one swoop!\n\nPS...try Panda Virus Scan, the professional edition...it's the best on the market, with hourly updates on newest viruses!

viruses don't contain any enzymes.  They may encode transcriptase, but they don't contain it.

each virus is different, so you'd need to know which one it was...or know in-depth how your os works (and that is a book, not a post at yahoo answers)
