Can Antivirus Slow Down Internet Speed?

Can Antivirus Slow Down Internet Speed?

This publication will discuss cases where antivirus software slows down the speed of browsing sites in the browser, as well as cases when the anti-virus reduces the speed of connecting to the Internet as a whole.

Many users are wondering if antivirus software can slow down the speed of the Internet. However, the answer to this question is not as clear as we would like.

In this article, we will describe to you the situations in which the antivirus program only slows down the process of viewing sites in the browser (without affecting the speed of the Internet connection itself), as well as situations in which the antivirus really reduces the overall speed of the Internet connection.

  • To protect your computer from network and external threats, the antivirus uses various scanning methods. If a particular type of scan is not supported by a particular browser, it may take longer to load pages.
  • If on the computer, in addition to the antivirus, other protection software is also installed, this can slow down the system. In such cases, when you try to connect to the Internet, the speed may be relatively low.
  • Often the speed of connecting to the Internet depends on the hardware and functional features of browsers. In particular, users will definitely encounter problems related to Internet speed if they use antivirus with outdated computer models.
  • If the version of the antivirus installed on the PC is out of date, it will take longer to open the pages. Therefore, make sure that the software and browser are updated in order to avoid problems with the Internet speed associated with the use of antivirus.
  • Sometimes when you turn on certain firewalls, add-ons and browser extensions, a conflict with the antivirus program may occur. This is why it is best to avoid applications that can affect the Internet and slow down download speeds.
  • If there is not enough free space on your PC’s hard drive, but you have installed antivirus, this can slow down the speed of Internet access.

Windows XP rootkit infections

Posted in Antivirus, Avast, Microsoft
The anti-virus vendor Avast alerts that unpatched Home windows XP machines still pose a significant threat to the web ecosystem by harbouring 75 % of rootkit infections.

The organization comes with an unique understanding of the threat landscape because of over 130 million active Avast! anti-virus installations worldwide that send it adware and spyware telemetry. Based on a current analysis carried out through the firm’s scientists, 74 percent of 630,000 rootkit samples based in the wild came from from Home windows XP machines.

This rootkit infection minute rates are almost two occasions greater compared to decade-old operating system’s global usage share of 38 percent. Avast’s statistics reveal that 49 percent of their clients have XP running on the computer systems.

The amounts show the high Home windows XP infection count can’t just be described by its share of the market. “One problem with Home windows XP may be the large number of unlicensed versions, especially as customers are frequently not able to correctly update them since the software can not be validated through the Microsoft update,” stated Przemyslaw Gmerek, Avast’s leading rootkit expert.

Rootkits are serious risks simply because they function in the cheapest quantity of a operating-system, causing them to be tough to identify. For instance, some rootkits hook the file system motorists to cover malicious files.

Others even operate outdoors the OS, providing them with a lot more treatments for machine. They are known as bootkits simply because they infect a partition’s Master Boot Record (MBR) and, based on Avast, they have the effect of 62 percent of rootkit infections.

The very best MBR rootkit family is called Alureon, TDL or TDSS. The most recent variant, TDL4, is capable of doing self-propagation and may infect 64-bit versions of Home windows Vista and Home windows 7.

False Positive Issue Quick Resolution by Avast

Posted in Antivirus, Avast

Yesterday [2011-04-11] a number of my clients called in the afternoon me in regards to some antivirus related activities on their computers. Something really weird was going on on all computers. Avast was flagging most of the websites as infected. There was nothing going on the PCs and even after a ran the AVAST scan and a couple of other anti-malware scans and did  not find anything the website were kept on being blocked.

Luckily, after a definition upgrade on one of the PCs (by the way done by the CEO of the company) the issue was resolved. My clients use the Small business Server and Standard suites so the updates on the workstations was done almost within a few minutes simultaneously on all of the computers after which everything went back to normal.

It really took about a couple of hours between noticing a problem and solving it. I consider this is not as bad as it could have been.

I’m a bit surprised how quick Avast responded to the problem, solved the problem and also posted a blog describing it.

“Virus definition update 110411-1 contained an error that resulted in a good number of innocent sites being flagged as infected. Generally, all sites with a script in a specific format were affected.

Our virus lab staff discovered the problem quickly after releasing the bad update and immediately started working on a fix. The fix was released about 45 minutes after the problematic update and has version number 110411-2. Anyone who still has this problem is kindly asked to manually update the definitions to the latest version, e.g. by right-clicking the avast taskbar icon (the orange (a) ball), and selecting Update -> Engine and Virus Definitions.

We sincerely apologize for the inconvenience. As this typically only affected remote sites (and not local files), simply updating to the latest definitions should completely solve the issue (no local files have been quarantined).” –  Avast blog said.

Malware can steal your private information

Posted in Antivirus, malware

This is not an ordinary virus and not all anti-virus programs can catch it. When this virus gets into the computer it can not be stopped.

It a new bread of virus called malware. This malware controlled by  a “cyber brain,” it gets into your computer, sets up a an environment inside of your PC, and then starts stealing your most important information.

“Even the safest surfers can be subjected to this sick scheme. One minute you’re minding your own business, the next you get a message that your computer is infected, and if you don’t pay $59.99 for what’s supposed to be Microsoft anti-virus, your computer stops working. But as one local couple found out, paying that fee doesn’t fix anything, in fact it makes matters worse.”

Posted in Antivirus, malware, Security

Based on a survey conducted by Barracuda Networks, spam level was down by about 50% in the second half of 2010. However the there was a 55% rapid increase in malicious software.

Barracuda Networks chief research officer Dr Paul Judge said that the shift towards search engines and social networking sites means fraudsters are now focusing on those areas of the internet.

“The research community must continue to build innovative defences and the industry must make efforts to increase the deployment rates of those defences,” Dr Judge added.

Avast Free Antivirus

Posted in Antivirus, Avast, Security

Avast Free Antivirus 6.0 gets 9.0 editor’s ranking at Cnet.com

Avast made great strides in its previous update. Version 5 set the stage for the modern, massively popular and free security suite with a new interface that ditched a quirky, late-’90s jukebox style for a more polished look. Easier to navigate, it also became easier to add new features.

Make no mistake, Avast 6 adds features both big and small. Some that had previously only been available to paid upgrade users are now free for all versions and newer features have been seamlessly added to the interface experience. If you’re familiar with Avast 5, upgrading to Avast 6 won’t be that big of a leap.
