How Egyptions Stayed Connected

The Egyptians still had a few ways to communicate although they were struck down by lack of internet due to the Government demanding the ISPs cut the channels. Several old school ways of communication allowed the few dedicated techs to accomplish 'work-arounds' to the blacked out internet.

One of the old school ways was to revert to ham radio which allows voice and also data communications although data can be much slower than through wires. Another old school technique was for the Egyptians to resort to dial-up where they were able to connect through outside connections.

A set of instructions was available on 24-7israel.com. The dialup connections allowed some Egyptians to remain connected if they were able to access the dialup information or have it delivered to them via ham radio or a set of instructions printed and hand-delivered. 

The crisis that appears to be continuing although the internet has reportedly been restored. Perhaps now they are able to restore and repair their computers if they received cyber attacks prior to the internet going down. They can download antimalware signatures and perform computer repair and laptop repair if the opposition was able to successfully infect and damage computers before chaos errupted.

Beware of Valentine Spam

Valentine spam has already began as reported in a blog on Symantec's website. PC Virus Doctors would also like to warn about possible malicious scripts buried in the emails that may deliver malware. Once an email is opened the script is generated that can be the beginning of the end if users do not have proper anti-virus or other anti-malware installed to notify users of potential problems or to actually stop malicious activities before they have a chance to gain foothold.

A good practice is to not allow oneself to be duped by emails or tempted to open them by just checking those boxes and reporting them as spam or simply deleting unsolicited emails. Refraining from these 'tempting Valentine's offers' may easily save a computer repair or laptop repair.

Intel Reports Sandy Bridge Recall

Intel is recalling the Sandy Bridge chip, according to an article by the Guardian. It is reported that Intel may have to spend up to One Billion Dollars to repair the design flaw. The setback will affect hundreds of models of computers and the delay will last about three months.

Sandy Bridge combines processing power and graphics into one chip but the flaw would eventually affect DVD drives and hard drives, according to the article. The chip's design flaw effects more than 500 models and is slowing the current downturn of new computer purchases in the Unites States and other regions.

Intel reports that 5% of the processors would have caused failure over a three year period if the flaw had gone unnoticed, according to the Guardian. The new silicon chips must be redesigned and manufactured so the newly designed chip will most likely not be available until April.

If Intel had not corrected the design flaw in the Sandy Bridge chip it would have led to inevitable computer repair and laptop repair.

Antivirus.net- Rogue Antivirus

PC Virus Doctors' Computer Repair has ventured across another rogue antivirus called Antivirus.net on a laptop repair. This fake antivirus is stealthy and it appears it entered the system via a Java exploit. One clue is that Java reports that updates are available, however, Java will not update nor will Windows 7 allow Java to be uninstalled.

Another characteristic of Antivirus.net is that Internet Explorer (IE) would not connect to the internet and only some antimalware programs would install while others would not install. Also Kaspersky would not uninstall even with Kaspersky's removal tool.

Disk checks can sometimes get users out of jams and helps to avoid PC repairs. Sometimes the system files can get corrupted and not allow some of the functions like the above problems.

Add to Egypt's Great Dead- the Internet

Security sources confirm that Egypt's shutting down of their internet is the world's worst in internet history. 97% if the internet has been severed in Egypt which has disrupted social networking sites such as Facebook and twitter but the cell phone service has also lost signal. The only carrier supplying any internet capability at this time is the Noor Group which supposedly connects Egypt's Government and banking organizations to the world wide web.

The internet was cut off Thursday at 2234 GMT simultaneously with four major internet providers whom have said they have a legal obligation to respond to such requests. World leaders have urged Egypt to restore the internet and the social networking sites but it appears the country's leader is ignoring any requests. The unrest continues as people are defying curfews to protest.

The implications are great as not only social networking sites are down but also the ability to communicate in times of health and welfare.

Also people referring to the internet to do business and carry-on business has been disrupted which could have devastating effects on the economy. PC Virus Doctors depend on the internet to perform computer repair and laptop repair on software systems and we would also be crippled if such events took place.

Open Source Internet Security Suite- FREE

PC Virus Doctors' Computer Repair is constantly on the lookout and spreading the word about freeware and keeping computers as locked down and secure as possible as security threats loom about. ClamWin has always been suggested as a 2nd backup antivirus if pc users are utilizing another free edition of a proprietary antivirus.
An open source internet security suite is Spyware Terminator and ClamWin that can be integrated allowing HIPS, a Host Intrusion Protection System; this system notifies users when exectubles are activiting during normal computer use. Users may then examine the exectuble(s) and have the choice to either allow or disallow.
