To make a long story short, I've had a lot of issues with my computer. It's a Dell about 4+ years old, worked great for the first 2-3 years and then the problems began. Yes, I know I need to buy a new one, but just can't afford one at this time and would like to keep going with this one for the time being.

About a year ago, the computer started crashing a lot, with a loud clicking sound coming from within the mid-tower case. I was led to believe (through various troubleshooting questions here and with friends) that the hard drive is probably corrupted. A while later, I contracted a virus that I was able to remove with help from Hijack This and this forum. Computer worked reasonably well after that, but continued crashing periodically and reached a point where I could no longer boot it up. The hard drive was wiped and XP re-installed. The comp worked reasonably well for months after that (but still crashed with the clicking sound fairly often).

Lately this has gotten out of control. It crashes a lot. I was using Firefox for the last couple of years and about 2-3 weeks ago, the computer started rebooting as soon as I launched a Firefox browser. I tried to install Google Chrome, same issue. It just reboots before the program is opened. Same thing when I try to run the anti-virus program. However, IE works in this scenario, which is what I've been using for the past couple of weeks.

Today I am getting messages about a virus that has been contracted. It seems like my Firewall/Anti-Virus is picking it up, but I can't run the anti-virus program to remove it entirely because of the reboot problem mentioned above. I have deleted all cookies and temporary internet files.

Anyone familiar with the rebooting issue? I'm hoping someone can help me out with a quick fix to end that problem, so that I can return to using Firefox, and also run my anti-virus scan properly. Any help would be appreciated, feel free to move this thread if I'm in the wrong forum.

Here are the messages I'm getting now every time I load up a web page (there are 2 different ones):

# 1: A virus has been found. Rogers Online Protection could not quarantine a detected virus. The file was deleted instead. Run the virus scan to verify that other files on your system are not infected.

Name: Trojan.JS.Redirector.ar
File: C: /Documents and Settings/Username/L.../show_ads[1].js

# 2: A virus was detected and quarantined. The file could not be disinfected, and was quarantined instead. Run the virus scan to verify that other files on your system are not infected.

Name: Trojan.JS.Redirector.ar
File: C: /Documents and Settings/Username/L.../show_ads[1].js

Seems like at this point the trojan has been contained by my firewall/anti-virus program, but still needs to be removed, and I assume the "redirector" is why these two messages pop up every time I load a web page. Thanks in advance for your assistance.

Guess I should add a post here before somebody starts working on this one, the hard drive was definitely messed up. Just bought a replacement yesterday and so far it's working perfectly, except for one problem which is not virus-related. So, problem solved.

Sorry for the delayed response but we are all volunteers and sometimes a topic thread will get overlooked.

Thank you for letting us know.

Tips to protect yourself against malware and reduce the potential for re-infection:

Keep Windows and Internet Explorer current with all critical updates from Microsoft which will patch many of the security holes through which attackers can gain access to your computer. If you're not sure how to do this, see Microsoft Update helps keep your computer current.

Avoid gaming sites, porn sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs (i.e. Limewire, eMule, uTorrent). They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Malicious worms, backdoor Trojans IRCBots, and rootkits spread across P2P file sharing networks, gaming, porn and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans, and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. Porn sites can lead to the Trojan.Mebroot MBR rootkit and other dangerous malware. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.Beware of Rogue Security software as they are one of the most common sources of malware infection. They infect machines by using social engineering and scams to trick a user into spending money to buy a an application which claims to remove malware. For more specific information on how these types of rogue programs and infections install themselves, read:Keeping Autorun enabled on USB (pen, thumb, jump) and other removable drives has become a significant security risk as they are one of the most common infection vectors for malware which can transfer the infection to your computer. To learn more about this risk, please read:Many security experts recommend you disable Autorun asap as a method of prevention. Microsoft recommends doing the same.

...Disabling Autorun functionality can help protect customers from attack vectors that involve the execution of arbitrary code by Autorun when inserting a CD-ROM device, USB device, network shares, or other media containing a file system with an Autorun.inf file...
