what is the worst virus infection your pc has had

I was never badly infected, but I am extremely careful. I remember I had my browser hijacked once, but it was easy to fix - bur an annoyance until I fixed it :) I check every single thing even when it comes from friends, and my anti virus did catch some virus that were in email messages or in files that I downloaded but I never opened them so the virus was just there. I do not open .exe files even if they're emailed from someone I know. I don't really download things from the net, WHen I do download something I don't open it until I have checked it, I am careful with the sites I go,I don't allow things to run automatically if I don't know what they are or if they are not really necessary, I scan my computer regularly and ge all the updates from my antivirus. Nobody is free from catchy some nasty virus but being aware of what is there and how to protect our computer is very important.

well im ok now, i have a good antivirus and all so i dont have any worries.... but my worst was a nightmare, i was battling it for days omg..... i was trying out some stuff with the firewall and stuff, and tried to open a file that was blocked by my previous antivirus, it was something i really wanted and i was too young to really know i shouldnt... lol well i managed to open it, then all my files were randomly deleted and my pc became very slow, i tried deleting the file and scanning with an antivirus and stuff, but it woulldnt go away, then one day it said i have some missing files in windows and that it cant load :((((

I just got my computer back after it got infected with spyware. What should have been a 3 hour job, ended up turning into a weeklong nitemare. My computer was infected with so many viruses and spywares....more than this technician had ever seen. I was supposedly being protected by verizion security suite. The tech told me that verizon just does not work. He has seen more computers trusting that protection than any other. He put the norton antivirus on my computer and I have to go and purchase spyware protection. He said the spyware protection is even more important than the antivirus.

The one i remember the most is this virus that had a enter button that would pop up. It killed my windows and when u hit said enter button it installed more viruses and well i got a drive erase tool and wiped it clean twice and then installed linux cause I had already was tired of the viruses that are for windows thank god Linux is not as in as windows

The worst virus infection I have ever had would be back when the blaster worm virus was still going around. You know, the virus that would shut down any windows XP system connected to the internet. It was pretty frustrating. All in all, I am glad that norton finally came out with a fix for it.

My PC has been infected by trojans it had given me great problem for several days my PC was not working properly then i got mcaffe it deleted all the virus form my computers

I'm not that technically minded so I don't know the names of all these viruses and things but the worst "attack" I sustained was a downloader trojan. I was surfing a traffic exchange, then the anti-virus warning popped up to let me know a trojan had been identified and then the next thing I knew my browser was hijacked. Then all this p0rn started downloading onto my pc!! It was a nightmare - took ages to sort and cost me a fortune. At the time I was using Norton (which I wouldn't recommend to anyone) but now I use AVG and I have to say I have never had any problems since switching to it.

I am a very ardent believer in "prevention is better than cure"and, wow, I have never suffered a virus threat to all my PCs, let alone network. Just not yet, perhaps. :)

We don't have malware problems on our machines, and Gizmo himself gave me URLs to 9 hostile sites for testing before he introduced my blog/site in the 150th TechSupportAlert newsletter. My solution works for Windows XP and 2000: http://invincible-windows.blogspot.com/

For someone who has been operating PCs for 10 years now, I must say I've not had any bad experiences with viruses. All these years, I've only used Norton Antivirus software on my computers, and I usually update the virus signature files diligently at least few times a month. That does not mean that I do not end up with viruses in my PCs. In fact, I do have my share of viruses, and some of these Norton have failed to get rid of even after detection. I usually let the viruses sit in my computer, and (touch wood) they have not caused any harm to my system. I reckon most of these viruses are dormant ones, or they only spring to life under certain conditions. Every few years, I will either change a new harddisk or reformat it and reload the entire system again, so that gets rid of viruses inherent in my system that I have not removed previously. Nowadays, I am more worried about spyware and keyloggers than viruses, because I believe these can cause more harm and are more malicious. I always make sure that I use the on-screen keyboard when I need to key in sensitive information like bank IDs and passwords for my internet-banking accounts. I've not had any trouble with my accounts being breached by keeping to this practice.

its good that you have been able to get rid of your computer of a particular virus.... i too had a similar situation when i got infected by i think a malware....i tried macafee and others too...but it would not go away... then i tried installing NOD32 antivirus and to my surprise the malware was completley gone and could not be traced back...

trojan.what we do is we reformat the computer

My PC was infected with trojan and it had given many problem.But now I am that I had avast antivirus which delete virus from my computer.
