Hardware diagnostic tools pc

This simple check can tell you whether a particular website is down , and if it isn't, then your inability to connect may be the result of some other problem, such as malware infections blocking or redirecting you from a site. Verdict: A quick tool that does exactly what it says and can help reveal signs of infection. Moving on to online security diagnostics , first up is Symantec's Security Check, a free online utility.

A two-part tool that first checks your browser , system , and anti-virus for common vulnerabilities, and then runs a quick, on-demand virus scan for common threats in critical areas of your system.

Unfortunately, the scan itself depends again on ActiveX controls , an iffy proposition if you're not using Internet Explorer. Verdict: While the system security scan is neat and useful for plugging potential vulnerabilities , the requirement for ActiveX controls limits the utility for anyone not using IE. What's more, the antivirus feature does feel somewhat superfluous if you already have an antivirus suite installed.

Russian antivirus firm Dr. Web provides a free online file and website scanning tool that allows users to quickly check if a particular file, archive, or download URL is infected. Select individual files or archive them, and then upload to Dr.

Web, which will run a virus scan based on the company's database of known viruses and malware. You can also send a download link to the Dr. Web service , which will scan the download for known malware. Verdict: While it's not a replacement for a dedicated security suite , Dr.

Web's online file checker gives you an extra layer of security , allowing you to check files being shared or linked to you before clicking on the download. Verdict: While too tedious to use with every link out there, you can use this tool to check on suspicious or innocuous links received out of the blue from friends and contacts. It's not infallible , but again, adds extra protection to your internet use.

Essentially a cloud antivirus scanner , Bitdefender's free scanner operates through a browser extension, and is a fast-working scanner that checks for malware and viruses active in your memory or within your startup files. While this should detect many infections , it's not as thorough as a true deep scan. Verdict: Somewhat superfluous if you already have antivirus , but it is a very quick on-demand scanner.

Jotti is an online service that allows you to scan a file for viruses and malware. What makes it different is that instead of using just one antivirus scanner , it sends them out to several different antivirus companies and then tells you whether or not any of the companies classified the file infected.
